To avoid livelocks, posted events should be delivered when all pending
messages have been processed, and the thread's message queue becomes
empty. Although the logic of the previous patch is correct, it turned
out that determining the moment when the message queue is really empty
is not so simple. It is worth noting that the GetQueueStatus function
sometimes reports unexpected results due to internal filtering and
processing. Indeed, Windows docs say that "the return value from
GetQueueStatus should be considered only a hint as to whether
GetMessage or PeekMessage should be called". Thus, we cannot rely on
GetQueueStatus in unambiguous logic inside the qt_GetMessageHook.
To solve the problem, this patch introduces a guard timer which
guarantees low priority processing for posted events in foreign loop.
The wakeUps flag reset logic has also been changed to provide clearer
synchronization of the Qt internal loop.

DeleteLaterWidget is a main application window of the test. So, its
show() function should be called explicitly before starting the main
event loop. Otherwise, it remains hidden for the whole time, which
causes an incorrect emission of QApplication::lastWindowClosed signal
when a dialog window is closed in the middle of the test.
Also, fix synchronization between deferred deletion and timer event.

The former option to clang will result in more options to the linker,

of the binary. Going with the clang driver gives us the right

the test code is compiled, which is more or less pointless; it's the

These message hooks are used to handle ALT+ENTER to enter/exit fullscreen
mode and PRINTSCREEN to take screenshots. Qt is implementing these
functionalities itself so we do not have to register these hooks.
If too many of these hooks are registered, callbacks are no longer called
and Qt's message queue is no longer handling messages. By saving these
hooks we can make sure that more Qt windows at the same time are possible
without getting unresponsive due to too many hooks being registered.

With nested popup widgets, pressing a mouse button on the lower
popup will close the active popup. MouseMove events that are generated
before the button is released again should not have that button
included, as it is likely to result in incorrect state handling in
the widget. This change removes all buttons from the MouseMove event,
which is the second best option.
This is mostly consistent with the behavior when closing a popup and
no other popup remains. The widget underneath will get MouseMove
events without the respective button included.
This change doesn't include a fix for the final release event, which
should ideally also not be delivered to the remaining popup, as it
never got a corresponding press event. Qt has already reset the states
in which it stores which widget received the press event at the time
the release is generated, such as qt_button_down and qt_popup_down.
So we can't separate a release grabbed by a newly opened popup (which
we want) from a release to the popup that became active after closing
(which we don't want).
However, widgets can more easily work around this issue, and the risk
of breaking things by changing the code further becomes too high.

[ChangeLog][QtCore][QCborValue] fromCbor() now limits decoding to at
most 1024 nested maps, arrays, and tags to prevent stack overflows. This
should be sufficient for most uses of CBOR. An API to limit further or
to relax the limit will be provided in 5.15. Meanwhile, if decoding more

Flushing sublayers via QImage copies of the root IOSurface was causing

We now re-use the QCALayerBackingStore implementation for sublayers,

We're still paying the CPU cost of the copy from the root backingstore
to the layered backingstores, as well as the memory cost, but at least
improves the situation.
We do not try to be smart and paint directly into the sublayers,
as that would leave the root backingstore stale, potentially causing
glitches when views are repositioned. Investigating this is left
for future work.

Constantly re-reading the timezone information only to be told the exact
same thing is wildly expensive, which can hurt in operations that cause
a lot of QTimeZone creation, for example, V4's DateObject - which
creates them a lot (in DaylightSavingTA).
This performance problem was identified when I noticed that a
QDateTime binding updated once per frame was causing >100% CPU usage
(on a desktop!) thanks to a QtQuickControls 1 Calendar (which has a
number of bindings to the date's properties like getMonth() and so
on).
The newly added tst_QTimeZone::systemTimeZone benchmark gets a ~90%
decrease in instruction count:
--- before
+++ after
PASS : tst_QTimeZone::systemTimeZone()
RESULT : tst_QTimeZone::systemTimeZone():
- 0.024 msecs per iteration (total: 51, iterations: 2048)
+ 0.0036 msecs per iteration (total: 59, iterations: 16384)
Also impacted (over in QDateTime) is
tst_QDateTime::setMSecsSinceEpochTz(). The results here are - on the
surface - less impressive (~0.17% drop), however, it isn't even
creating QTimeZone on a hot path to begin with, so a large drop would
have been a surprise.
Added several further benchmarks to cover non-system zones and
traverse transitions.

qWaitForWindowExposed() returns. Because we check later to see whether
it moved, we need to be certain of its initial position.
Waiting for the extra "fleece" widget to be shown was based on the
theory that by the time the X server has processed messages related
to that new window, the WM should be done processing the consequences
of the resized dialog window. But there's no such guarantee, so let's
try removing that. On the other hand, removing the delay does open
us up to miss a regression (maybe the dialog gets moved after we have
