9ff40b59da Fix QDockWidget parenting and dock permissions
Check DockWidgetArea permissions of QDockWidgetGroupWindows with single
dock widget. Obtain a dock widget's tab position from a dock widget
group window if it can't be established otherwise. Remove hardcoded
assumption that a dock widget is in the left dock. Both cases have lead
to inconsistent entries and dangling pointers in
QDockAreaLayoutInfo::item_list.
Remove warning: QMainWindowLayout::tabPosition called with out-of-bounds
value '0', which becomes obsolete by the fix.
Create a QDockWidgetGroup window prepered to become a floating tab,
whenever a dock widget is being hovered over. Store it in item_list so
it can be found and deleted when required.
No longer call e->ignore() after propagating close events to the first
dock widget and thus preventing others from receiving the event.
Add logging category qt.widgets.dockwidgets
Update dock widget autotest with tests to check the fixes mentioned:
plugging, unplugging, hiding, showing, closing and deleting.

8254ee6a3b CMake: Fix implementation of qt_apply_rpaths
There were a few things that were not ported correctly.

Make sure to disable rpath manipulation if the rpath feature is
disabled.

Fix if(IS_ABSOLUTE) conditions to actually take values.

Don't embed bogus relative rpaths if the platform does not support
it. QNX is such a platform, it does not support $ORIGIN (at least from
my scouring of QNX documentation and manual testing via QEMU).

Handle the extra rpath case where they are relative, but the platform
does not support relative rpaths, by transforming them into absolute
ones.

5059f7adc2 CMake: An -extprefix -developer-build should install by default
Previously if
 -extprefix /tmp/sysroot (CMAKE_STAGING_PREFIX)
 -developer-build (FEATURE_developer_build)
were specified, but
  -prefix (CMAKE_INSTALL_PREFIX)
was not,
the build system would set the CMAKE_INSTALL_PREFIX to the
qtbase build dir.

Then, if targeting desktop, this would be considered a non-prefix
build (ninja install would refuse to work), whereas in a cross-build
it would be considered an installable build.

In both cases though, the rpath of installed binaries would point to
the qtbase build dir (because CMAKE_INSTALL_PREFIX would be set to the
qtbase build dir).

This is quite confusing behavior, in more than one way.

Change the build system to consider that an explicit -extprefix should
cause Qt to always be installed, even if -developer-build is
specified.

This means the installed rpaths and on-device install prefix
(CMAKE_INSTALL_PREFIX) will now use the default computed install
prefix, e.g. /usr/local/Qt

It also means that to get a non-installable developer + custom staging
and install (on-device) prefix build, users will have to be explicit
and set all the options
 -extprefix ~/qt/qtbase_build_dir
 -prefix /usr
 -developer-build

f3483e6b96 CMake: Allow no install + custom on-device prefix for desktop builds
Allow such a combination
- staging prefix (CMAKE_STAGING_PREFIX / -extprefix) set to the
  qtbase build dir
- install prefix (CMAKE_INSTALL_PREFIX / -prefix / on-device prefix) set
  to some custom location
even for non-cross builds.

An example would be
    configure -prefix    /usr \
              -extprefix ~/qt/qtbase_build_dir

CMake will put the Qt libraries in the qtbase build dir, ninja install
will not be required, but ultimately in order to run applications,
the Qt libraries are expected to be in /usr.

Support for this scenario was originally added for cross-builds in
062318feb2 , but not desktop builds.

Such a build is useful when you want to have install rpaths different
from where Qt is initially installed to (the staging prefix).

This case doesn't really happen often when targeting desktop
platforms, it's mostly used for cross-compilation (e.g yocto).

Being able to have the same setup with a desktop build is nevertheless
useful for faster iteration on build system issues in such a scenario.

475ac94374 CMake: Fix no_prefix feature to take into account the staging prefix
Instead of complicating the condition even more, just use the value of
QT_WILL_INSTALL which is determined in QtSetup before configure.cmake
is loaded.

The AUTODETECT part is needed to ensure that
 -developer-build
implies -no-prefix.

The CONDITION part is needed so that
 -extprefix /tmp/sysroot -no-prefix
correctly errors out saying that this can't be a non-prefix build,
unless
 -extprefix ${qtbase_build_dir} -no-prefix
is passed.

830b1550de Fix race condition in futex-based QSemaphore
Add one and reset the wakeAll bit atomically.

This avoids a race in a case where an acquiring thread
is owning the semaphore, and deleting it after a
set number of releases (one for each thread referencing the semaphore).

Two releasing threads could enter the if statement under
futexNeedsWake(prevValue), the counter been incremented at
this point and reached the value being acquired, meaning the thread
acquiring can be awakened by just one of the two releasers,
delete the semaphore, and then the second releaser would access
the now deleted semaphore.

The patch avoids that by unsetting and reading the wakeAll bit
atomically, so only one thread will try to wake all threads.

da0f72ebb8 QEvent: start to de-inline copy ctor and clone() of all subclasses
There's no advantage to them being inline: Absent de-virtualisation,
clone() is only supposed to be called through the vtable, and the copy
ctor is only supposed to be used in the implementation of clone().

And when the compiler de-virtualises, we don't want the code
duplication associated with inlining.

Enforce this by introducing new macros to hide the boilerplate.

This fixes missing out-of-line dtors in:
- QSinglePointEvent
- QApplicationStateChangeEvent
- QFutureCallOutEvent

Wrong covariant return in:
- QFutureCallOutEvent

And missing clone() reimplementations in:
- QCloseEvent
- QIconDragEvent
- QShowEvent
- QHideEvent
- QDragEnterEvent
- QDragLeaveEvent

While these don't carry extra data or members, a dynamic_cast of the
result of clone() as well as using the expected covariant return value
would fail:

   QShowEvent *e = ~~~;
   QShowEvent *e2 = e->clone(); // ERROR: converting QEvent* to QShowEvent*

Check that reimplementing clone() is binary compatible (covariant
returns may change the numerical pointer value returned, cf.
https://community.kde.org/Policies/Binary_Compatibility_Issues_With_C%2B%2B).

The copy-assignment operator stays inline for the time being, as the
goal is to = delete it in the future.

This patch covers, roughly, QtCore and QtGui.

[ChangeLog][QtGui][QEvent subclasses] Fixed missing clone()
reimplementations on QCloseEvent, QIconDragEvent, QShowEvent,
QHideEvent, QDragEnterEvent, and QDragLeaveEvent.

For all new elements, this is the correct thing to do. This seems to
work around an MSVC compiler bug on ARM64. It also seems to generate
better code for x86-64 too, as a nice bonus.

7de83f06c1 QDateTime: add conversions for time_point and zoned_time
In C++20, QDateTime is a direct equivalent of a sys_time<milliseconds>
time point. (Before, it might not have been, because system_clock before
C++20 was not guaranteed to be tracking Unix time, AKA UTC time without
leap seconds.) To be specific, sys_time<milliseconds> corresponds to
a QDateTime using the Qt::UTC timespec.

This patch:

1) adds named constructors taking time_points:

* a generic one taking any time_point convertible (via clock_cast) to
  a system_clock (this obviously includes system_clock, but also e.g.
  utc_clock)

* another couple taking local_time, interpreted as a duration from
  1/1/1970 in local time.

2) adds a named constructor from zoned_time (i.e. a sys_time + a
   timezone), that we can easily support via QTimeZone.

3) add conversion functions towards sys_time, matching the existing
   to(M)SecsSinceEpoch() functions.

[ChangeLog][QtCore][QDateTime] QDateTime can now be constructed
from std::chrono::time_point objects (including local_time), as
well as from std::chrono::zoned_time objects. Moreover, they
can be converted to std::chrono::time_point using system_clock
as their clock.

2e29f55f76 QDate: add conversions for std::chrono calendaring classes
std::chrono::year_month_day and related classes offer very
convenient to specify dates.

This patch adds implicit constructors to QDate to support this
convenience, e.g.:

  // YYYY-MM-DD, DD-MM-YYYY, MM-DD-YYYY formats:
  QDate d1 = 1985y / December / 8;
  QDate d2 = 8d / December / 1985;
  QDate d3 = December / 8d / 1985;

  // Indexed weekday:
  QDate d4 = 2000y / January / Monday[0];
  QDate d5 = 2000y / January / Monday[last];

and so on.

These are all implemented using the conversion from the std
calendaring classes to sys_days. Conversions between sys_days
and QDate are also added, since they're basically "for free".

I don't expect "ordinary" users to stumble upon it, but it's
worthy mentioning that std::chrono::year *does* have a year
zero (hence, year_month_day in year 0 or below are offset
by one with the corresponding QDate). I've left a note
in the documentation.

[ChangeLog][QtCore][QDate] QDate (and therefore QDateTime)
is now constructible using the year/month/day/week classes
available in the std::chrono library. Moreover, it now
features conversions from and to std::chrono::sys_days.

33c88f86b5 QAbstractProxyModel: do not access invalid indexes
QAbstractProxyModel::headerData tries to do the "smart" thing and
map sections in the proxy to sections in the source. However there's
no "mapSectionToSource" virtual. Instead, to map horizontal headers, the
code builds a proxy index at row 0 and section N, maps it to the source,
and finds out which source column it gets mapped to. (Same story
for the vertical headers).

... in general this can obviously fail, say you've got a "horizontal
scrambling" proxy model, but in the common case this is OK.

Except, if the proxy is empty (e.g. 0 rows or columns). In this case,
it asks for an illegal index, and if you reimplemented index() yourself
(which you must, since it's a pure virtual in QAPM) and you do bounds
checking, you'll not be pleased at the result.

This turns out to be a massive API liability. To fix this somehow properly,
we can decide that empty models don't get the section remapped (easy).
Less easy is the fact that, when the model does get some data, we have to
emit headerDataChanged() otherwise the views will get broken. So add
this logic too.

Note that QAPM does not normally forward any source model's signal -- a
subclass has to connect to them and handle them explicitly. That's
*another* API liability, all over the place -- data(), headerData(),
flags(), etc.

What I mean by this is that one can create a valid QAPM (by implementing
its pure virtuals) that however is immediately broken by the convenience
that QAPM provides for the rest (data(), headerData(), etc.).

This commit doesn't try and change this in any way, but I'm less and
less convinced of the usefulness of QAPM in its current shape.

743bb66744 Avoid rebuilds when changing sources belonging to bootstraplib
Whenever a source file is touched that belongs to the bootstrap library,
all bootstrap tools are rebuilt.  This includes moc.  The moc binary
however, is a dependency whose invalidation results in a rebuilt of
quite some parts of Qt.

There's no easy way to turn off this dependency.  To mitigate the
rebuilds, the bootstrap lib now can use a copy of the corelib sources.
That means the bootstrap lib is not rebuilt if its sources are changed.
This is basically the situation we had in Qt5.

The sources are not updated on reconfiguration.  There's a new target
'update_bootstrap_sources' that can be built to update the copied source
tree of the bootstrap lib.

This new behavior can be controlled with the variable
QT_USE_BOOTSTRAP_SOURCE_COPY.  It's on by default for developer builds.

7a7023b7b1 Chip example: fix an accidental bool->int conversion when using PMF connections
The example was refactored to use the PMF connection syntax.
However this introduced a problem: when connecting a QAbstractButton
to a slot that has a default parameter, the semantics of the connection
change between string-based connections and PMF.

Specifically: when connecting the

  QAbstractButton::clicked(bool checked = false)

signal to a slot like

  View::zoomIn(int level = 1)

then a string-based connection like

  connect(button, SIGNAL(clicked()), this, SLOT(zoomIn()))

would call zoomIn without carrying the signal's parameter over.
In other words, zoomIn's parameter is defaulted. The same connection
using PFM instead is

  connect(button, &QAbstractButton::clicked,
          this, &View::zoomIn)

which would "connect" the arguments. This makes emissions that pass
false as clicked's parameter result in a zoomIn by 0.

Fix it by avoiding the default parameter of zoomIn -- just split
the function in two (zoomIn and zoomInBy).

Amends 8cf8122314.
