ac310d5b23 [macOS] Add native virtual key code to modifier keys
Not forwarding the native virtual key code when sending key events
in the flagsChanged handler caused a number of problems, e.g. the
inability to determine which of the Alt or Shift keys were pressed.

Use handleExtendedKeyEvent to include the native virtual key code.

Patch inspired by Nyan Pasu.

8186bd628f Remove obsolete APIs and comments from QAbstractPrintDialog
Merging QAbstractPrintDialog with QPrintDialog, as proposed in the
removed comment, seems to have little value, given that the platform
specific implementations rely on the current abstraction.

Adjust examples and tests; with the QAbstractPrintDialog test now
testing the QPrintDialog::options API, the corresponding test function
can be removed from the QPrinter test.

7238123521 X11: set fallback logical DPI to 96
Returning physical DPI from logicalDpi() is problematic,
as explained in commit 77e04acb.

The most predictable implementation is to never return
physical DPI from QPlaformScreen::logicalDpi(). Other
platform plugins already does this, and this change
brings xcb in line with the rest of Qt.

We have the QPlatformScreen::physicalSize() API which
covers returning physical DPI (indirectly); Options
for selecting which one to use can be implemented on
top of these (see QT_USE_PHYSICAL_DPI).

a81859a3c8 Move grabbing API from QEventPoint to QPointerEvent
We plan to move storage of the grabbers into QPointingDevice so that
QEventPoint will store only data that does not need to persist between
deliveries of individual events. These API changes prepare for that.

addPassiveGrabber/removePassiveGrabber is a better API than
setPassiveGrabbers(), because it will never require constructing a
temporary QList just to call the function. Eventually we need to emit
signals to notify about grab changes, so it's better to have incremental
changes to the list rather than needing to iterate and find differences.

Fix up the docs.

QEventPoint IDs are no longer written in hex in debug output.
That was done in Qt 5 because an ID was a composite of device ID
with the OS-provided touchpoint ID; but since the QPointingDevice
is always available, it's more readable if the IDs are in decimal.

db3d5a3097 Fix flaky QTimer::remainingTime() test
Before, we used not so accurate QTest::qWait(50)
to measure the accuracy of more precise timer's interval.
In addition, the checked range for remainingTime (50, 200)
was probably wrong, since by definition it couldn't be more than 150,
as we started the timer with interval of 200 and waited at least 50.

In this fix we have additional "tester" timer to measure remainingTime
of "tested" timer. The "tester" is a singleShot timer with interval of
50, and is started together with "tested" timer. Whenever the "tested"
timer timeouts, it restarts the "tester" timer - this is done desired
number of times (2 by default, like in the original test).

The test itself lies now inside tester's lambda. We fix the tested
range (at least 1, no more than 150). The minimum value could in
theory be greater, but it's enough to test that it's not overdue.

Finally, we wait for expected number of test runs. We give it twice
as much time as is in theory needed.

948f2a9cac CMake: Don't hardcode Xcode SDK frameworks into public dependencies
Using find_library() to find an Xcode framework will end up embedding
the absolute path of the framework into INTERFACE_LINK_LIBRARIES.
A different machine might not have the SDK installed in the same
location, which will cause build failures. This happens in our CI
because Xcode is installed to /Applications/Xcode11.app.

To fix this, replace all system framework paths with
'-framework Foo' flags instead.
We already do this for OpenGL and OpenGL ES.

In the future we might want to convert these into full standalone
FindFoo scripts that expose proper targets.

7e93870401 QProcess/Unix: introduce setChildProcessModifier()
[ChangeLog][Source-Incompatible Changes] QProcess::setupChildProcess()
was removed. To execute code in a child process, use
QProcess::setChildProcessModifier()

[ChangeLog][QtCore][QProcess] Added setChildProcessModifier() function
with which one can provide code to be run in the Unix child process
between fork() and execve(). With this function, it is no longer
necessary to derive from QProcess in order to execute actions in the
child process.

Another reason is that we can tell whether the std::function carries a
valid target much more easily than we can tell whether QProcess was
overridden.

The setupChildProcess() virtual function does not need to be marked
final, since no overrider could ever return an inaccessible private
class. This also makes sure the error presented to the user is about the
return type, not about attempting to override a final.

Clang:
 error: virtual function 'f' has a different return type ('void') than the function it overrides (which has return type 'QProcess::Use_setChildProcessModifier_Instead')

GCC:
 error: conflicting return type specified for 'virtual void MyProcess::setupChildProcess()'
 note: overridden function is 'virtual QProcess::Use_setChildProcessModifier_Instead QProcess::setupChildProcess()'

ICC:
 error: return type is neither identical to nor covariant with return type "QProcess::Use_setChildProcessModifier_Instead" of overridden virtual function "QProcess::setupChildProcess"

MSVC is not relevant since it doesn't compile to Unix.

679184ac28 QSemaphore: Make 64-bit wide
The implementation can be more efficient with two 32-bit fields instead
of just one, but it depends on whether operations on 64-bit atomics are
locked or not.

Quick check for the following architectures does not reveal any
problems, but someone needs to investigate more. Notably, GCC and Clang
generate a call to libatomic's __atomic_load_n / __atomic_store_n / etc.

32-bit                  std::atomic<uint64_t>
Arch            ::is_always_lock_free   .is_lock_free()
ARMv7-A         false                   true
i386            false                   true
MIPS            false                   true

475464906c Revert "Cleanup QSemaphore and make it always 64bit large"
This reverts commit ff69227a49.

Reason for revert: 64-bit atomics on 32-bit systems are often
(but not always) worse than the 32-bit semaphore as it was
implemented. Plus the High32 and Low32 functions are returning
the same thing, forgetting the endianness check.
