c8473c0903 macOS: Use submenuAction: as action for sub-menu menu items
Having the generic qt_itemFired: as action would result in the whole
submenu tree closing if an item with a sub-menu was clicked on. This
is not how native applications behave. They respond by immediately
opening the submenu, or do nothing if the menu is already open.

By using submenuAction: as the selector we achieve the same behavior.

A complication here is that for some reason we defer associating the
submenu NSMenu to an NSMenuItem until QCocoaMenu::setAttachedItem(),
instead of doing it in QCocoaMenuItem::setMenu(), or even as part of
QCocoaMenuItem::sync().

As a result, AppKit's NSMenuValidation logic will conclude that the
item does neither have a submenu, nor a valid target/selector combo
to be validated, and will explicitly disable the item. This can be
debugged by passing -NSTrackMenuValidation YES to the application.

To work around this we explicitly enable the item once we have set
a valid submenu for the item.

af8f9a2a6e QStringBuilder: allow to be used with 'auto' keyword
The idea is to store a concatenable in a QStringBuilder object by value
or by reference, depending on how it was originally passed into the
concatenation operator. So if it was passed by r-value, we treat it as
a temporary object and hold it by value (and use move-semantic if
available), otherwise we hold it by reference (as before).

To achieve this we first change concatenation operators '%' and '+'
to take their arguments by universal reference. Next we instantiate
QStringBuilder object with deduced types of the arguments, which will
be a "value type" or a "reference type" according to "universal
reference deduction rules".

Further we use perfect forwarding to pass arguments to QStringBuilder's
constructor. Thus arguments, initially passed by r-value reference
and which are move-constructible, will be "moved" to corresponding
QStringBuilder member variables.

So, to summarize:
1. Arguments passed by l-value reference - stored in QStringBuilder
   object by reference (as before).
2. Temporary objects passed by r-value reference - stored in
   QStringBuilder object by value. If a type is move-constructible
   (QSting, QByteArray, etc), the object will be "moved" accordingly.

Special thanks to Giuseppe D'Angelo for the tests.

8d1304f4f2 QGtk3Interface: Explicitly add monospace font provider
In case the current GTK3 theme has no monospace font defined, a
monospace font requested by a Qt application can trigger a GTK warning
"Theme parsing error: <data>:1:0: Expected a valid selector".
The warning is triggered by Qt requesting "{font-family: monospace;}".

In this case:
=> ensure fallback to GTK standard monospace font
=> request "* {font-family: monospace;}" to avoid the warning

72d660843b QCoreApplication: port processEvents() to QDeadlineTimer
As Eddy pointed out in review, the existing overload API docs says using
this method is discouraged; but adding a QDeadlineTimer overload is more
about preventing overflow, as it can handle qint64 or
chrono::milliseconds.
So it's either add this new overload or change the existing one to take
a qint64.

[ChangeLog][QtCore][QCoreApplication] Added processEvents() overload
that takes a QDeadlineTimer.

3c12c3d58c Deprecate some older Apple platform defines
Clang's macro deprecation pragma was introduced in Clang 14,
shipped with Xcode 14.0.

We can't version check Q_CC_CLANG here, as qcompilerdetection.h
hasn't been included at this point. Nor would it have helped much,
as we would have had to do so for each individual define we wanted
to deprecate, since mentioning an undefined define in the deprecation
pragma is an error. And we can't wrap the pragma in another macro
that conditionally expands to _Pragma either, as the input argument
is a define that needs to be passed on as is, without expanding it.

So the simplest way to support < Xcode 14 is just to silence
the unknown pragma warning.

4c18ebbc1c wasm: expose windows before delivering updates
Don't show a blank frame on app startup.

The wasm update request system supports two types of update
requests: Expose and UpdateRequest. It can happen that both
types of request are made for a single window, in which case
the current code prefers UpdateRequest, since those must be
delivered in order to keep QWindow in a consistent state.

However, if the window is visible but not yet exposed then
delivering the update request will not make the window paint
anything, and we end up with a blank frame.

Ideally this should be handled elsewhere and QWindow::requestUpdate()
should not be called for non-exposed windows, but in the
case does happen then sending an expose here allows us to
recover.

b209f943d2 Replace {add,sub,mul}_overload with q{Add,Sub,Mul}Overload
These APIs started out as private APIs in qnumeric_p.h, but have since
been made pseudo-public in qnumeric.h. The qnumeric_p.h versions just
forward to the qnumeric.h ones, so just use the latter.

This is in preparation of removing the {add,sub,mul}_overflow
versions, which, despite being defined in the unnamed namespace, don't
sport the q prefix, so potentially clash with global symbols.

The change is a simple textual search and replace, manually excluding
qnumeric_p.h.

Picking to 6.5 to avoid cherry-pick conflicts going forward.

dcf7604230 QVariant::value/qvariant_cast: add rvalue optimization
If we have a rvalue reference to an unshared QVariant, we can avoid
potentially expensive copies, and use move semantics instead.

[ChangeLog][QtCore][QVariant] Added rvalue QVariant overloads of qvariant_cast<T>() and QVariant::value<T>().

[ChangeLog][Potentially Source-Incompatible Changes][QVariant] It is no
longer possible to take the address of a specialization of
qvariant_cast; consider using a lambda function instead.

b1ee49b465 Q{Any,}StringView: optimize lengthHelperContainer for the runtime
Deduplicate it in the process by moving to qstringalgorithms.h.

In non-constexpr contexts, both GCC and Clang were giving up in
pre-calculating the length if the UTF-16 string literal was too big. For
the old code, that was 14 and 16 characters respectively. That number
can be raised by adding some Q_ALWAYS_INLINE and (for GCC's case),
replacing std::char_traits::find() with std::find(). If that limit is
exceeded, we call the newly introduced qustrnlen() function.

qustrnlen() is just qustrchr(), like qstrnlen() is just memchr(). But it
is introduced as a separate function so we could change implementation
if we ever wished to, plus QStringView is only forward-declared at this
point.

95e6fac0a5 Short-live qIsConstantEvaluated()
This is not q20::is_constant_evaluated() because it does not replace
that for all compilers. Instead, it's our own version of it that may
return false even in constant contexts. However, for the majority of our
users, it will work even in C++17 mode.

Updated QStringView and QAnyStringView to use it, which are the only two
places in all of Qt that used std::is_constant_evaluated().

631901f6d1 Q{Any,}StringView: remove the GCC-specific compile-time content
Because GCC isn't really working them out at compile time. First, for
both lengthHelperPointer(), they don't get called on string literals
such as

  return QStringView(u"Hello");

because the type hasn't decayed to a pointer, but is instead a
char16_t[6]. No one writes

  constexpr auto str = u"Hello";
  return QStringView(str);

Second, even when you do write that, GCC is emitting the code to search
for the null or non-ASCII byte at runtime, instead of pre-calculating
it. That's not worth it because the code is not vectorized, even at -O3
and with a long string. Instead, let it get the length at runtime with
QtPrivate::qustrlen(), which has vector code.

Drive-by fix the QAnyStringView::lengthPointerHelper() to be constexpr,
avoiding the same GCC warning that was fixed for QStringView in commit
4fd4082c3a.

5ea0256b07 rhi: Don't check m_format in QRhiSwapChain::hdrInfo()
The HDR info is independent of the current format anyways.
Removing the format check allows code to use hdrInfo() as
a signal for whether to set a HDR format, instead of having
to set the format, then query hdrInfo(), and then setting
SDR again if needed.

74319d05b1 rhi: Pick up HDR maxColorComponentValue from UIScreen if available
Although QRhiSwapChainHdrInfo uses 'max' for this value, it's used
by Qt Multimedia's QVideoWindowPrivate::render() as the current
maximum, so we need to reflect UIScreen's currentEDRHeadroom
rather than potentialEDRHeadroom (the absolute max), the same
way we reflect maximumExtendedDynamicRangeColorComponentValue
and not maximumPotentialExtendedDynamicRangeColorComponentValue
from NSScreen.

As we don't support HDRExtendedSrgbLinear on < iOS 16 there
is no point in providing a heuristic fallback based on the
iPhone 12 spec.
