fa67cd0334 Use boolean to indicate QTableWidgetItem is header item
QTableWidgetItem uses additional enum flag ItemIsHeaderItem which has
the same numerical value as ItemFlag ItemNeverHasChildren.
This causes conflict since the user can set the latter flag using
the setFlags, while the ItemIsHeaderItem is only used internally
to mark header items.

Remove the additional flag and use boolean instead to fix the conflict.

2434573f5e QTabBar: don't overshoot when scrolling right
Amends ca15f650a1, after which scrolling
right to fill any gap might have resulted in overshooting to a negative
scrollOffset.

When we scroll right to fit the current tab, then we never want to end
up with a negative scroll, so clamp the result accordingly.

Augment test case accordingly. Since some styles align the tab bar in
the center, replace the calculation of the scroll offset with access to
the private data member (which inverts the sign when compared to the
calculated value).

7d75039482 Make default local time a static const
QDateTimeParser::fromString(), when parsing a date-time, uses the
start of 1900, in local time, as its default date-time. (This is a bad
choice and steadily getting worse.) This turns out to be somewhat
expensive for some client code, so make it a static const so that we
only compute it on the first call, as for getM{in,ax}imum().

The potential downside is that a change to system time zone won't be
reflected in this value. However, any sane parse-format should require
over-writing all fields of this initial value, in any case, so the
issue is less severe for this default value than for the existing
getM{in,ax}imum() statics.

5c05eb3ea0 macOS: Don't clam to support action messages from non-Qt menu items
As described in 3bedeb837e, the way
menu items on macOS are typically set up they have an action, e.g.
copy:, but no target, and the system then takes care of finding the
right target at runtime, starting with the first responder, walking
the responder chain, and then moving on to other NSWindows, before
ending up in the NSApplication and its delegate.

As we (still) don't have a mechanism in Qt to forward generic
actions, such as the cut/copy/paste, or selectAll, so we rely on
mapping the actions back to QCocoaNSMenuItem that we can trace
back to a QPlatformMenuItem that we in turn emit activated() for.

Normally this works fine, but in the case where the Qt app is embedded
in a native UI, which has its own menu items with cut/copy/paste,
we'll get callbacks into QNSView for actions triggered by a generic
NSMenuItem.

In that case, we need to bail out, but we want to do so in a way
that lets AppKit continue to walk the responder chain. This is
possible by implementing supplementalTargetForAction:sender:,
where we have access to the sender. If sender doesn't match
the expected QCocoaNSMenuItem we let AppKit find a better match
up the chain.

Since the target we return needs to ultimately respond to the
selectors and/or forward them, we can't point the target back
to ourselves, nor can we point it to the application delegate
directly, as the menu items need to be validated in the context
of the view, so a new per-view QNSViewMenuHelper class has been
added to take the role of forwarding the menu actions.

The logic for forwarding the resulting actions to the application
delegate has been simplified and hardened a bit as well.

A possible scenario with this new approach is that the Qt app
has a line edit focused, and the user tries to activate the
menu item for Paste, but the item is grayed out because we
can not support the action. This is of course confusing for
the user, but less so than having an active menu item that
then doesn't do anything when activated.

Another scenario is that a responder later in the chain does
respond to the paste action, and the menu item will end up
pasting into something that is not the first responder.
This might also be confusing for the user, but it's generally
recommended that implementers of actions like paste only
allow the action if the view is the first responder, and
this is something views have to deal with anyways, so it
doesn't change anything that we're now bailing out earlier
in not accepting the paste.

One benefit of allowing AppKit to find a better target for the
action is that if no target is found, and the user presses the
key equivalent of the disabled menu item, the key event will
be delivered as a normal keyDown to our QNSView, which we do
forward, allowing the Qt app to respond to the action, even
though the action came from a generic menu item. With our old
approach this would not happen, as we would claim to support
the action for our QNSView, but then drop it on the floor when
AppKit tried to deliver it to us.

re-check something that should be known already.

To fix, then, use a while (true) loop and react on first == last and
dst == end() separately.

90d3c5b951 QDBusServer: Fix potential crash when private pointer is null
Check that the private pointer is not null before attempting
to dereference it. This can happen, for example, when
a QDBusServer instance was constructed with an empty string
as address. Attempting to destroy an object constructed
this way was causing a segmentation fault on Linux.

Add a test case that attempts to construct a QDBusServer
object with an empty string as address to check that this
does not cause a segmentation fault anymore.

29b2506e8c Allow disable native messagebox dialog
The native style may not match the program style and it
makes sense to give an option rather than forcing native style.

Before it could only be done with setting AA_DontUseNativeDialogs
on the app, but it is reasonable to use native file dialogs and
Qt styled messageboxes - and it is extremely cumbersome - especially
since messageboxes often can start save dialogs.

It can look a bit strange that these introduced options has just one
option (DontUseNativeDialog) and four functions, but this way it works
similar to QColorDialog, QFileDialog and QFontDialog.

[ChangeLog][QWidgets][QMessageBox] Added options functionality to
QMessagebox. The currently only option available is DontUseNativeDialog.

8598e84c5f QMutex & QReadWriteLock: do a memory read before CAS
The testAndSet operation is expensive if the lock is contended:
attempting to CAS that lock will cause the cacheline containing the lock
to be brought to the current CPU's most local cache in exclusive mode,
which in turn causes the CPU that has the lock to stall when it attempts
to release it. That's not desirable if we were just trying an untimed
tryLock*.

In the case of timed, contended tryLocks or unconditional locks, we
still need to perform an atomic operation to indicate we're about to
wait. For that case, this patch reduces the minimum number of atomic
operations from 2 to 1, which is a gain even in the case where no other
thread has changed the lock status at all. In case they have, either by
more threads attempting to lock or by the one that has the lock
unlocking it, this avoids the cacheline bouncing around between the
multiple CPUs between those two atomic operations. For QMutex, that
second atomic is a fetchAndStore, not testAndSet.

The above explanation is valid for architectures with Compare-And-Swap
instructions, such as x86 and ARMv8.1. For architectures using Load
Linked/Store Conditional instructions, the explanation doesn't apply but
the benefits still should because we avoid the expense of the LL.

959800f6de Short live Q_NODISCARD_CTOR
[ChangeLog][QtCore] Introduced Q_NODISCARD_CTOR which resolves to
[[nodiscard]] attribute for constructors on compilers that support
it, and does nothing on other compilers.

Using [[nodiscard]] attribute on a constructor is a C++20 feature,
however in practice it is supported on most of the compilers that
we use in Qt 6. Clang generates a [-Wunused-value] warning, GCC
and MinGW generate a [-Wunused-result] warnings, and MSVC
generates a C4834 warning.
However, there are some exceptions.

The Integrity compiler provides the following warning:
 "tst_qglobal.cpp", line 699: warning #3435-D:
           the "nodiscard" attribute doesn't apply to constructors,
           destructors, or routines with void return type
           [[nodiscard]] explicit Test(int val) : m_val(val) {}

The QNX compiler (QCC 8.3.0) and GCC 9.3.1 on OpenSUSE generate
the [-Wattributes] warning:
 tst_qglobal.cpp: In member function
   'void tst_QGlobal::nodiscardConstructor()':
 tst_qglobal.cpp:699:44: warning: 'nodiscard' attribute applied to
   'tst_QGlobal::nodiscardConstructor()::Test::Test(int)' with void
    return type [-Wattributes]
          [[nodiscard]] explicit Test(int val) : m_val(val) {}

These warnings will lead to build failures when compiled with
-warnings-are-errors flag, so for these compilers the macro
does not do anything.

An attempt to use __attribute__((__warn_unused_result__)) was
also unsuccessful on these compilers, so this patch goes for
an easy solution, and simply checks
 __has_cpp_attribute(nodiscard) >= 201907L
to decide if the attribute is supported or not.

This commit also introduces a syntax-only test, and also applies
the new macro to QMutexLocker, because not all platforms in the
CI build and run unit tests.

4160817050 macOS: Don't leak QEventDispatcherUNIX during event dispatcher creation
During QCoreApplication initialization, we create the main thread's event
dispatcher, which for a GUI app happens via QGuiApplicationPrivate's
createEventDispatcher() override. This in turn relies on the platform
integration to create the event dispatcher, but to do that it needs to
create the platform integration first. And this might result in calling
APIs that themselves initialize the main thread event dispatcher, such
as QEventLoop, which non-lazily creates an event dispatcher for the thread.

We already had a check to catch the platform integration setting the
QCoreApplictionPrivate::eventDispatcher member, but not anything for
checking the current thread data.

On macOS this resulted in a leak of QEventDispatcherUNIX because
QCocoaDrag contained a QEventLoop member. We now track the event
loop temproarily via a pointer instead, like we do in other places.

An alternative fix would be to defer the initialization of QCocoaDrag
until QCocoaIntegration::drag() is called, but that would run the
risk of something calling the function during platform initialization
and we'd be back to the same problem.

It's unclear why QEventLoop is not lazily ensuring the event dispatcher,
and this might be a wider fix for similar issues.

968250ee14 QMetaProperty: add write() overload taking rvalue QVariant
The existing overload unconditionally copies the QVariant, causing it
to unconditional detach in most cases (when calling data() later).

The rvalue overload need not preserve the source object, so doesn't
need to copy.

Implement the lvalue overload in terms of the rvalue one, but keep the
sanity check in both to avoid copying the QVariant just to find that
there's nothing to do.

Following the copy, there were some references to the source object,
but they can all be replaced by references to the target object
instead, which hasn't been touched by then, yet.

[ChangeLog][QtCore][QMetaProperty] Added write() overload taking an
rvalue QVariant.

127e33d4c6 Don't set focus when moving the cursor with a touch pad
On macOS, swiping with a single finger on the track pad (which Qt
identifies as a QInputDevice::DeviceType::TouchPad) results in a
TouchBegin event. For widgets that accept touch events (perhaps
implicitly because they want pan gestures, like QGraphicsView),
this results in a TouchBegin event to be delivered.

QApplication::notify will then check the widget's focus policy, and with
ClickFocus set, will set focus on the widget.

This is not what we want for a TouchBegin on a touch pad, so skip the
setting of the focus for that device type.

c2f01d4cfb QVariant: Fix support for metatypes created by Qt < 6.5
In Qt >= 6.1, < 6.5, a trivially constructible type would have the
NeedsDestruction flag set, but it's dtor pointer would have been null.

In Qt 6.5, the meaning of the NeedsDestruction flag was changed to be
more aligned with what the name suggests, and thus would only be set for
non-trivially destructible types. For QMetaType this was fine, but
QVariant has a check for acceptable metatypes which attempts to verify
whether a QMetaType is usable for QVariant. The check assumes the
semantics of Qt 6.5, and thus fails for metatypes created by older Qt
versions.

To fix this issue, we increment the QMetaType revision field, and only
check the metatype's destruction support if the revision is high enough.

In theory, that allows passing unsuitable metatypes from older Qt
versions to QVariant; however, such code would have been broken in prior
Qt releases already (which didn't attempt the check), and no code that
used to work in any released Qt version will break (as we simply skip a
check that was passing before).

Amend 207aae5560, as code checker
complained that we std::move'd a potential lvalue. This warning was
valid if the public API did not accept the functor parameter by value.

Fix this by consistently std::forward'ing the parameters through the

the helper API didn't work with free functions, so fix that as well. It
also revealed that QFunctorSlotObject couldn't work with a const
functor, which is also fixed by this change.

We cannot support move-only functors with that change, as it requires
a change to QFunctorSlotObject that breaks the QMetaObject test.

4db9fdf58e macOS: Avoid memory leak when using NSSlider for style drawing
To fix the broken sliders reported in QTBUG-98093 a workaround was
added by 4bee9cdc0a where we would
call initWithFrame on an already initialized NSSlider.

This breaks the contract of object initialization in Objective-C,
as the class is free to allocate and prepare resources for the
instance without freeing previously acquired resources first.
As noted by the Object Initialization chapter of the Concepts
in Objective-C Programming guide, "Once an object is initialized,
you should not initialize it again.":

    https://tinyurl.com/objc-object-init

And as observed in QTBUG-112899, the additional initialization
resulted in a memory leak.

The other part of 4bee9cdc0a
was that we now called startTrackingAt twice when drawing.
Both from setupSlider, for all consumers, and from
drawComplexControl, and as it turns out, this is the key
thing that "fixes" the pressed knob drawing of NSSlider.

For some reason, NSSlider needs the duplicate startTrackingAt
call both to draw the knob as pressed, and to not let one
drawing pass affect another drawing pass. This would benefit
from further investigation, but for now the removed leak
is an improvement.

2cd7e34fa0 Add more shortcutmap categorized logging output
Show more detail about the checks made against each entry to show why
a shortcut might not get delivered. Specifically, it's useful to know
if the contextMatcher returned true. In the case of Qt Quick Controls,
it can return false if the Shortcut is blocked by a modal popup, or
a popup with a CloseOnEscape policy.

With this patch, combining qt.gui.shortcutmap with
qt.quick.controls.shortcutcontext.matcher makes it possible to see
which popup blocks a shortcut. With only the former enabled, it's
already quite useful:

qt.gui.shortcutmap: Possible shortcut key sequences: QList(QKeySequence("Ctrl+N"))
qt.gui.shortcutmap: - checking entry 0 QKeySequence("Ctrl+N")
qt.gui.shortcutmap:   - matches returned 2 for QKeySequence("Ctrl+N") QKeySequence("Ctrl+N") - correctContext()? false
qt.gui.shortcutmap:   - matches returned 0 for QKeySequence("Ctrl+N") QKeySequence("Ctrl+O") - correctContext()? false
qt.gui.shortcutmap: Found better match ( QList(QKeySequence("Ctrl+N")) ), clearing key sequence list
qt.gui.shortcutmap: Added ok key sequence QList(QKeySequence("Ctrl+N"))
qt.gui.shortcutmap: Returning shortcut match ==  0
qt.gui.shortcutmap: QShortcutMap::nextState(QKeyEvent(ShortcutOverride, Key_N, ControlModifier, text="N")) = 0

af95ec4b7b QApplicationStatic: enforce acquire-release semantics on creation
On systems with weak memory ordering, it was possible for the
storeRelaxed(Initialized) to be observed by another thread performing a
loadRelaxed() without observing the contents of the object itself. The
mutex *does* release the contents of the object to memory, but without
the corresponding mutex acquisition, we couldn't guarantee that the
object's contents would be observed. Now we can.

We don't need to fix the load inside the mutex because the mutex will
have acquired everything from either a previous call to pointer() or to
reset(). The store inside reset() need not be storeRelease() either
because the effect of observing the Uninitialized state will be to lock
the mutex.

None of this is used to protect the data as it is being mutated by the
user in multiple threads, or their access simultaneously with reset()
(which is why the load outside the mutex was removed).

Thanks to litb on Slack for noticing this and bringing to my attention.

207aae5560 Simplify the creation of APIs that take a callback
Functions in Qt that take a callback need to support callables with or
without context objects, and member functions of an object. The
implementation of those overloads follows a pattern that ultimately
results in a QSlotObjectBase implementation being created and
passed to an implementation helper that takes care of the logic.

Factor that common pattern into a new helper template in QtPrivate
that returns a suitable QSlotObjectBase after checking that the
functor is compatible with the specified argument types.

Use that new helper template in the implementation of
QCoreApplication::requestPermission and QHostInfo::lookupHost.

The only disadvantage of centralizing this logic is that we cannot print
a more detailed error message indicating which argument types the
caller expects. However, that information is visible from the detailed
compiler errors anyway.

5ddb5d1fee Rework imagescaling example to avoid potential crashes
Creating a continuation with QtFuture::Launch::Async policy does not
work well with the example, because it still needs to update the UI
once the async continuation is finished. If the user decides to
close the application while the async continuation is executed,
the next continuation will be accessing data from the destroyed
Images object.

Fix it by using QtConcurrent::run() to do the "heavy" work in a
separate thread, and use a QFutureWatcher to handle the results of
the async execution. Update the example documentation accordingly.

After this patch the example still shows the usage of continuations
and onCanceled()/onFailed() handlers. However, it now does not
illustrate the usage of different launch policies and continuation
contexts. It might not be a big issue, because the QFuture
documentation describes these topics rather extensively.

ca15f650a1 QTabBar: don't scroll when laying out the tabs
QTabBar lays out the tabs when the bar's size or content changes,
often lazily. This should not change the scroll offset of the tabbar,
which is controlled by the user, or at most when a tab needs to be made
visible (e.g. when it becomes the current tab).

Move the logic of updating the scoll offset into the makeVisible
function, so that the scroll is only adjusted to either leave no gap
between the last tab and the right edge of the widget of there is still
a scroll; or to reset it to 0 if there is enough space for the entire
tab bar. Since layoutTabs does show and hide the scroll buttons, we
cannot skip this when the buttons are invisible. However, the
normalizedScrollRect helper now needs to return the entire widget rect
if there are no visible scroll buttons.

Add a test case that simulates the previously broken behavior where
the scroll got unnecessarily reset to 0 when resizing.

55a51e1909 Implement QXmlStreamReader::hasStandaloneDeclaration()
This patch implements a public getter for the hasStandalone attribute.
It returns true, if standalone has been explicitly declared in an XML
header and false otherwise.

As this is no longer necessary it removes accessing QXmlStreamPrivate
from QDomParser.

b85a9d0ee1 Move QZipReader/Writer from QtGui to QtCore
These classes depend only on Core, not Gui.

This allows dropping the dependency of tst_qxmlstream and tst_qzip on
QtGui, and prevents a tst_qxmlstream FTBFS when building with
QT_NO_TEXTODFWRITER.

Symbols move from QtGui to QtCore, but the classes are private API, so
not under BC constraints.

The classes are not used outside qtbase, so no other in-tree users
need porting.

67431e4168 QMutex/Unix: remove the pthread_mutex_t-based content
For our purposes, the sem_t code is better, so we've preferred it since
commit c7ab816af1 (5.7). Olivier wrote in
that commit's message, "It makes tst_QMutex::contendedQMutex with no
msleep 8 times faster".

That's true because QMutex didn't lock the underlying pthread_mutex_t in
QMutex::lock(), as we used the inlined atomic code for the uncontended
case.

It is probably possible to merge the qmutex_mac.cpp and qmutex_unix.cpp
code now (both are based on semaphores), but I won't do that for two
reasons:
 1) At best, the PThread functions are going to be thin-wrappers around
    the code we already have, like FreeBSD's are around usem (see [1])
 2) Darwin has a private API that resembles futexes so we may want to
    go that way eventually (see [2])

a build issue because they aren't built. Moreover, the problems
were seen in another module, so the properties set in those files
shouldn't even be visible to CMake.

5ebb9a8bf3 Tune textures example to work with wasm and update docs
Old examples inherited from Qt 4 tend to set some state, such as
enabling the depth test or culling, in initializeGL(). Newer examples
tend not to do this; they rather set the necessary state in paintGL().

This mattered little (or not at all) in the past, but with WebAssembly
and WebGL there are limitations in the GL context management in the
wasm platform plugin. Under certain conditions, esp. when
QOffscreenSurface is involved, it looks like the same native context
gets reused, which means there is a chance of unexpected changes to
the current state between calls to initializeGL() and paintGL(). (and
also between paintGL() calls) See QWasmOpenGLContext for details.

Update the textures example the same way we did for the cube one.

Add a note to the QOpenGLWidget docs about this problem.

When the latter happens the display link thread will crash in

CVDisplayLinkGetCurrentCGDisplay(), so we follow the same
approach, and then bail out:

  https://bugzilla.mozilla.org/show_bug.cgi?id=1201401#c158

Once we bail out we fall back to the timer based approach
to delivering the update request. The next requestUpdate()

work this time around, as the display has had time to fully

11f14c3b0d QDomDocument: no longer drop a provided 'standalone' attribute if 'no'
- Definition of 'standalone' attribute:
An XML declaration containing the attribute 'standalone' with its
value set to 'yes', tells the parser to ignore markup declarations
in the DTD and to use them only for validation.
The declaration attribute is optional and defaults to 'no'.

- Behavior Qt5
In qt5, DOM documents contained the standalone attribute,
regardless of whether or not it was explicitly specified.

- Behavior Qt6
In Qt6, the standalone attribute was only contained in a DOM document,
if its value was 'yes'. If it was explicitly declared with the value
being 'no', it was dropped in the DOM document.

- Expected behavior
If the source specified it overtly, then the generated XML should
contain the attribute, even when it takes its default value.

- Code base
QXmlStreamReader provides a public bool getter isStandaloneDocument().
This says whether the document is standalone or not.
The information whether the attribute was actually specified gets lost.
In consequence, the attribute was always dropped on non-standalone
documents.

- Fix
This patch makes hasStandalone a member of QXmlStreamReaderPrivate, to
record whether the attribute has been explicitly specified.

QDomParser is modified to retain the standalone attribute, if
QXmlStreamReaderPrivate::hasStandalone is true.

- Test
The patch adds a test function in tst_QDom.

a92c202b49 macOS: Localize title of edit menu's NSMenuItem via AppKit
In 939b7bfe66 we synced up the NSMenuItem's
title to that of the corresponding NSMenu, as AppKit was observed to use
the NSMenuItem title for its heuristics of when to add dictation and
emoji entries to the menu.

But AppKit's heuristics are based on the localized name of the edit menu,
so we need to follow suit and look up AppKit's own localizations. This
is of course fragile, as we're relying on this localization continuing
to live in the InputManager table, but if that changes we'll just fall
back to using the title from the NSMenu, as we did before.

In addition, AppKit's heuristics also look for menu items in the menu
that match selectors such as copy:, paste:, etc, so even if our lookup
of the localized title fails, the additional heuristics would in most
cases still succeed in detecting the edit menu.

b1802a164b Handle parent being a child's focus procy in QWidget::setFocusProxy
When a parent became a new child's focus proxy in an existing focus
chain, the child was appended at the end of the chain.
That leads to broken tab order, e.g. with a QComboBox which became
editable after a focus chain has been set.

This patch captures the case and insertes the new child after its
parent in the focus chain.

A corresponding test function is added in tst_QWidget.

87535e4e43 QTimer: optimize single shot timers that cross thread
Amend 4d90c4e74a by clarifying why
moving the QSingleShotObject to the receiver's thread is a good
idea. Move that logic into a separate function and use that also
for the string-based connection.

Optimize the implementation by delaying the timer creation until
after we have moved the QSingleShotTimer object to the target
thread, using a queued metacall if needed to create the timer.
This avoids the creation of the timer in the wrong thread and
then the recreation of the timer in the new thread when QObject
handles QEvent::ThreadChange.

To avoid that the timer is created when it has already expired in
real time, use a deadline timer and fire timeout immediately when
it has expired by the time we get the metacall.

Since the timerId might now not be initialized in the constructor,
initialize it to -1.

Augment the crossThreadSingleShotToFunctor test function by
deliberately not starting the thread until the deadline expired.

[ChangeLog][Core][QTimer] Single-shot timers with a string-based
connection are now started in the receiver's thread, not in the
thread that creates the timer.

d4b40fa96b QTabBar: draw text within moving tab
When a tab was moved by dragging, the tab's rectangle was drawn empty,
without the tab text. When a tab was moved by animated snap back to
its original position, the tab text was already drawn on the original
position, while the rectangle was still moving due to animation.

Adds the enum value QStyleOptionTab::TabPosition::Moving
When this option is set, QCommonStyle draws the tab text at the
current position instead of the original home position of the tab.

The QMacStyle switches over the TabPosition enum. As a moving tab
is laid out like the last tab in the given orientation, the enum value
Moving is treated like End.

25530c7020 win: Fix default fallback font for some languages
In Qt 5, the system font would resolve to MS Shell Dlg 2, which
was always an alias for Tahoma. Since it was not a real font,
but a so-called "logical font", it was manually added to the font
database whenever we detected that the system font was not
automatically enumerated.

In Qt 6 we modernized the selection of system font. This causes
real fonts, such as Segoe UI, to be selected as the default and
the manual adding of "MS Shell Dlg 2" to the font database never
happens.

However, "MS Shell Dlg 2" was still preferred as the primary
fallback font, but we now always failed to resolve it because
it wasn't in the font database. For many writing systems not
supported by the main system font, such as e.g. Thai, people
still expect to get Tahoma as the default, but we now return
an arbitrary font from the alphabetically ordered list instead.

To work around this, we avoid returning the non-existing logical
font, since this is no longer useful, and just return Tahoma
directly.

[ChangeLog][QtGui][Text] Fixed an issue querying a default font
for certain languages not supported by the primary system font.

was nanoseconds. This could have been solved with function overloads
instead, but I find the if constexpr code simpler to read.

b498e1ae3a QDeadlineTimer: use std::chrono::steady_clock everywhere
This matches the work that was done for QElapsedTimer. The
QDeadlineTimer::t2 member is now always 0.

This also removes the last distinction of timer types. Originally I had
intended to use CLOCK_MONOTONIC_COARSE on Linux[1], but that created
more problems than was worth, so I abandoned the idea in 2016.

c9f4c0d45e QElapsedTimer: rewrite using std::chrono::steady_clock everywhere
This commit deletes the direct, low-level functionality that
QElapsedTimer has carried since it was introduced. Everything now uses
only std::chrono::steady_clock and std::chrono::nanoseconds.

QDeadlineTimer temporarily still uses qt_gettime(), which is moved to
qcore_unix.cpp.

eac30fcb82 QWaitCondition/Unix: use QDeadlineTimer's <chrono> support
We don't need to hand-roll our own conversions when QDeadlineTimer can
convert to the time points of any std::chrono clock. In particular, if
the clock we ask for is the clock its internal representation is already
storing, then it's more efficient too.

2a997942db QWaitCondition/Android: remove support for relative time waits
This actually saves two clock_gettime(CLOCK_MONOTONIC) system calls
(albeit to the vDSO): one inside QDeadlineTimer::remainingTimeNSecs() to
calculate the remaining time from the deadline, then one other inside
pthread_cond_timedwait_relative_np() to calculate the deadline from the
timeout, so it can place the FUTEX_WAIT_BITSET system call.

In fact, I can't find __pthread_cond_timedwait_relative() in the Bionic
source any more. The last reference was removed in 2015, when Bionic
started using FUTEX_WAIT_BITSET. So this commit is just removing dead
code in current Android.

840af18b8d QElapsedTimer/Darwin: merge with the Unix implementation
Old versions of the Apple operating systems did not implement the POSIX
realtime monotonic clock, so we used the Mach absolute timer. The LLVM
libc++ implementation[1] unconditionally uses CLOCK_MONOTONIC_RAW on
these OSes:
 * macOS >= 10.12
 * iPhoneOS >= 10.0
 * tvOS >= 10.0
 * watchOS >= 3.0

Qt 6 doesn't support the latter two and the former two are much older
than what we require, so we can use this functionality too.

e539e9a7af rhi: Replace the temporary GPU time query API with a saner one
Modeled after Metal's cb.GPUStart/EndTime. Implemented with timestamp
queries for other APIs.

Implemented for Metal, D3D11, Vulkan for now. No more callback, just
a getter on the command buffer which returns the latest known value,
referring to some previous frame. This makes it a lot more usable
than the original solution that is not really used anywhere at
the moment.

Now works for offscreen "frames" as well, this was not implemented
before.

Opt in with a new QRhi::create() flag because we cannot tell in
advance if the getter will be called or not, and this way we can
skip recording the timestamps by default. The cost is probably
minimal, though. Qt Quick will set this automatically when running
with QSG_RHI_PROFILE=1.

62a4ca773a rhi: Make it safe to always call deleteLater on a resource
...even when the QRhi is already gone. This should not happen in
well-written applications and libraries, but we handle this
gracefully in the regular dtor and destroy() for resources that
register themselves to their creator QRhi, so by registering
everything we can offer this to all QRhiResource subclasses.

We still want to differentiate between native resource owning
QRhiResources and others (that do not create native graphics
objects), so do this via a flag passed to registerResource().
This way the behavior with QT_RHI_LEAK_CHECK=1 does not change.

Depending on the corner that the size grip lives in, the style sheet

needs to be done around the center of the size grip, not around the

cb30e45b9a Avoid capturing same property twice
Avoid capturing the same property multiple times in a binding by
storing them in the BindingEvaluationState. We store them in a
QVarLengthArray array, as the number of properties involved in a binding
is expected to be rather low, so a linear scan is fine.

Avoiding double capture is a good idea in general, as we would otherwise
needlessly reevaluate bindings multiple times, and also needlessly
allocate memory for further observers, instead of using a binding's
inline observer array.

Even more importantantly, our notification code makes assumptions that
notify will visit bindings only exactly once. Not upholding that
invariant leads to memory corruption and subsequent crashes, as
observers allocated by the binding would get freed, even though we would
still access them later.

If the QOpenGLFramebufferObject (which owns the OpenGL texture object)
is destroyed, the wrapper QRhiTexture must be destroyed too.

This surfaced with WebAssembly for some reason, likely due to an event
(most likely resize) sending pattern that is different from other
platforms. Sending more resizes likely triggers another recreateFbos()
call which, until now, did not correctly dropped the wrapper
QRhiTextures so those continued to refer to the now-destroyed texture
IDs.

ffdfafc4b4 Ignore removed/changed screens if no QIOSIntegration instance exists
QIOSTracker registers itself as handlers for system notifications about
changes of the screen environment. If no QIOSIntegration instance
exists, newly detected screens are not added to the list of known
screens (see screenConnected()). This, in turn, will result in a crash
if a screen is disconnected and removed in screenDisconnected() as it
is not known to qtPlatformScreenFor() and the function returns a
nullptr.

Consider the QIOSIntegration also whenever a screen is "changed". This
is more of a safety measure do avoid crashes for unknown screens.

This situation occurs if an iOS device is used to mirror the display
via AirPlay and no actual QGuiApplication exists, e.g. Qt is only
embedded in a Framework.
