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.

Following wg21.link/LWG3228, it was found that a proper variant fix
requires that T* -> bool conversions be treated as narrowing
conversions in subclause wg21.link/dcl.init.lst. wg21.link/P1957R2 was
accepted in Prague 2020 as a DR and retroactively applies to older C++
standards.
Since we hard-code the algorithm of [dcl.init.lst], we can and must
add this manually.
[ChangeLog][QtCore][QObject] For the purposes of
QT_NO_NARROWING_CONVERSIONS_IN_CONNECT, pointer
(incl. pointer-to-member) to bool conversions are now considered
narrowing. This matches the resolution of a defect report in C++
itself.

Since the backend is async, the settings will not be ready to read/write
instantly as on other platforms, but only be ready after the
filesystem has been synced to the sandbox. This takes at least 250 to
500 ms. The QSettings status() or isWritable() can be used to discern when the
settings are ready for use.
This also fixes a crash in threaded wasm

Minimal fix for the missing wakeup issue, in leu of
a new event loop implementation.
So far, emscripten_async_run_in_main_runtime_thread_
looks to be our option for scheduling calls on the
main thread. This function is available on emsdk 1.38.22
and higher.
Requires making from QEventDispatcherUNIX::wakeUp()
non-final. The future event dispatcher implementation
will not inherit QEventDispatcherUNIX, so this is a
temporary change.

If a type has both a converter to QVariantList and to
QSequentialIterableImpl registered, we would have chosen the
QSequentialIterableImpl version. In the case of types like QJSValue,
this is more costly. With this change we therefore uses the direct
conversion if it has been registered.
The same applies to QAssociativeIterableImpl and
QVariantHash/QVariantMap.

This flag is used in QSequentialIterable and QAssociativeIterable to indicate
that the data pointer in VariantData should be deleted after the variant has
been constructed.
The use case for this is
https://codereview.qt-project.org/c/qt/qtdeclarative/+/284151, where we have
a proxy iterator and cannot easily return a pointer to already owned data, as
it is hard to manage its lifetime in the iterator. In contrast, it is clear
that we can release the memory in the QSequentialIterable functions, as it has
already been copied into the QVariant there.

Using wrappers for these macros is problematic when for example passing the
-frewrite-includes flag to preprocess sources before shipping off to distcc
or Icecream. It will also start producing warnings when compilers implement
http://eel.is/c++draft/cpp.cond#7.sentence-2. See for example
https://reviews.llvm.org/D49091
Both https://clang.llvm.org/docs/LanguageExtensions.html and the SD-6 document at
https://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations
recommend defining '__has_foo(x) 0' as a fallback for compilers without the
macros, so that's what we go for.

In 5bb178c479a247720fbc3fbb7f06a32b725193ac, the Android platform plugin was moved from
platforms/android to platforms/. The unforeseen consequence of this was that the plugin
loader for plugins/platforms would now find it, whereas before it would be ignored. It
would therefore be detected as the appropriate plugin, but since it was intended to be
loaded as a static plugin, loading it dynamically would fail.
Instead of fixing the static plugin loading, we remove this hack.

At first glance, libraryPathMutex is only recursive because
setLibraryPaths(), addLibraryPath() and removeLibraryPath(), all of
which lock libraryPathMutex, may call libraryPaths(), which does, too.
This is easily fixed by splitting libraryPaths() into public
libraryPaths() and private libraryPathsLocked(), the latter expecting
to be called with the libraryPathMutex already held. And this is what
this patch does.
However, on second glance, the building of the initial app_libpaths
calls a monstrous amount of code, incl. QLibraryInfo, and some of
that code probably re-enters one of the library-path functions.
So while this patch is a step towards making libraryPathMutex
non-recursive, it's probably not the end.

According to Windows docs, GetMessage() function retrieves the messages
from the input queue in defined order, where posted messages are
processed ahead of input messages, even if they were posted later.
Therefore, if the application produces a posted event permanently, as
a result of processing that event, user input messages may be blocked
due to hard CPU usage by the application.
It's not a problem, if an internal Qt event loop is running. By calling
sendPostedEvents() on the beginning of processEvents(), we are sending
posted events only once per iteration. However, during execution of
the foreign loop, we should artificially lower the priority of the
WM_QT_SENDPOSTEDEVENTS message in order to enable delivery of other
input messages.
To solve the problem, it is proposed to postpone the
WM_QT_SENDPOSTEDEVENTS message until the message queue becomes empty,
as it works for the internal loop.

... except four instances in QCoreApplication that would conflict with
another change.
Replace a locally-defined MutexUnlocker with a call to unlock() +
qScopedGuard'ed lock() to avoid having to spell out the locker type
while we can't depend on C++17 CTAD, yet.
In QSettings, move the new mutex locker into and out of
initDefaultPaths(), such as is idiomatic for std::unique_lock, but
wasn't possible with QMutexLocker (which is not movable).

As exposed by tst_QObjectRace::destroyRace we would sometimes end up
with a double-free when destroying a QSlotObject in multi-threaded
scenarios. One free would be done in ~QObject as the receiver was being
destroyed while the other free was done when deleting a QMetaCallEvent
object after we realized it was not needed because the receiver was
destroyed.
Since we can be in a separate thread from the receiver we should lock
before referencing the connection object.

There are two cases:
In a BlockingQueuedConnection, QMetaCallEvent doesn't allocate memory
and instead passes already existing pointers through. A QSemaphore
is used to serialize data access between threads. So the constructor
taking a QSemaphore can be simplified to only accept an existing arg
array.
In a QueuedConnection, QMetaCallEvent needs to make deep copies of
the arguments, and memory needs to be allocated based on the number
of arguments. The previous code put the burden of memory allocation
on the code generating the event, while the memory was free'd by
~QMetaCallEvent. Instead, make it QMetaCallEvent's responsibility
to allocate and free the memory as needed, and adjust the code
generating QMetaCallEvents.
We can allocate the memory for types and pointers to arguments in a
single block, starting with the space for the array of void*, followed
by the space for the array of integers to avoid byte alignment issues.
By pre-allocating the space that's needed by three arguments, we can
avoid all mallocs for the majority of QMetaCallEvents.
Until this change has propagated through qt5.git, we need to keep the
old API that is still used by QtDeclarative around. Once QtDeclarative
has migrated to the new API, it can be removed.

- add conditional noexcept to move special member functions
- use qExchange() in the move ctor implementation (turns a copy into a move)
- separate the default ctor from the ctor that acquires a resource, then
- overload the latter for rvalue payloads

This applies the changes to our other smart pointers that
a0c4b6f34546bdd22167a76a0540d37e9a37c0cf applied to QSharedPointer,
with the same rationale: wg21.link/p0551.
It also fixes a fwd declaration of std::function, including
<functional> instead. Rationale: wg21.link/p684r0.

29bcbeab90210da80234529905d17280374f9684, it seems like there are still
use-cases when QSignalMapper is useful.

Use the standard tool instead of self-made stuff that cannot decide whether
it wants to be a scoped pointer (why take()?) or a movable one (why no move
special member functions?).
Take advantage of C++11 local structs for pulling the custom deleter into
the scope where its only user is located, too.
