Unlike Q_GLOBAL_STATIC, a Q_APPLICATION_STATIC can be destroyed and
re-created multiple times (if QCoreApplication is, too). This means
we're basically in the std::optional case and require std::launder()
to avoid UB when the payload type has either of the following:
- a const member
- a reference member
- a vtable and different derived classes might be occupying the same
space at different times
While we can probably exclude the latter, because we always construct
the same type, PlainType, in the storage, the first two can easily
happen.
Fix by adding the missing std::launder().
As a drive-by, remove the uneeded casting (and now launder()ing) of
&storage when passing to innerFunction(), which anyway takes its
argument as void*.
Amends 81a31beeb2, which changed
Q_APPLICATION_STATIC to use inline aligned_union storage instead of
the original implementation's unique_ptr.

The previous attempt at fixing QTBUG-110058,
ccad719d2e, was incomplete:
- the if (result.isEmpty()) check at the beginning of finalize() was
not protected, so it raced against the assignment at the end of
finalize(), which was protected
- because the mutex was not locked during the finalization of the hash
algorithm, two threads could perform this operation simultaneously,
which isn't such a bad idea in principle, as it can reduce latency,
but for that to work, the losing thread needs to throw away its own
work and adopt the work of the other thread, but that wasn't done:
both threads would write their result to 'result', just one after
the other, but that's still a data race, since the eventual _reader_
of the result cannot be protected (is outside the class). Besides,
we don't even know whether the algorithm-specific finalization
functions are ok with being called from separate threads on the same
context object
- in addition, the mutex wasn't necessary when finalize() was called
from the static hash() function, as no sharing could possibly take
place there (the state is function-local)
Fix all of the above by largely reverting the first attempt, dragging
the result.isEmpty() check out of finalize() and into resultView() and
instead simply holding the mutex over these two calls in
resultView(). To see why this is sufficient, consider that
resultView() is now idempotent again: the result is written once, the
next thread waits and then finds the work done. All following accesses
to the result are then reads, which happen-after the write at the end
of finalize().
The accesses to 'result' from reset() need no protection, as reset()
is a mutable function, and calling a mutable function on a shared
QCryptographicHash object is already UB. Only two const functions may
be called that way.

There's no point in using the full implicit sharing machinery when the
type's state consists of two enums, a bool or, indeed, if the type has
no state at all. QRect has more state and isn't implicitly shared.
To remain extensible in the future, all that is required is that the
type contains space for an eventual d-pointer and that all access to
members (except swapping, and, as a consequence, the move SFMs, but
including the copy SMFs, ctors and dtor) is confined to out-of-line
functions.
So define a ShortData (name stolen from QDateTime) nested struct in
each of the stateful Q<Typed>Permission classes, of the same size as a
pointer, holding the trivially-relocatable fields we currently have.
If, in the future, fields are added such that the reserved[] space in
any given class' ShortData no longer suffices to hold them, or said
fields are not of Q_RELOCATABLE_TYPE, then the full d-pointer pattern
(with an actually defined Private, and detach()ing) can be implemented
_for that one class_.
The new-style classes are externally indistinguishable from the
implicitly-shared old-style ones, just a lot more efficient.
Inline the move-ctor, now that we can. This doesn't break
encapsulation, even when we eventually activate the d-pointer.
As a drive-by, drop the noexcept on the dtors - dtors are implicitly

QCoreApplicationPrivate::initLocale()'s check that the selected locale
is UTF-8-based was added with an initial work-around for Android,
specific to NDK <= 15, which Qt 5.15 did not support.
Later the Android-specific #if-ery was changed to test for Qt taking
UTF-8 for granted, for a given reason having to do with QNX; and later
the #if-ery for that was removed. However, we still support versions
of Android that lack nl_langinfo(), so restore the Android #if-ery.
It presently seems that NDK 26 (Android 8) does contain nl_langinfo(),
so we should be able to drop the nl_langinfo() kludge for this and
later versions. That way we'll at least use the real nl_langinfo()
where we have it.
In the process, fix the indentation of #if-ery.

Rename local var to lastVal, this is less confusing and less error

Apple sandboxes restrict use of the System V / XSI IPC mechanisms. It's

Linux system call filtration can do the same. In fact, systemd's
SystemCallFilter= options do default to SIGSYS too and it has an @ipc
group that could be used to block SysV. However, the same group blocks
the creation of pipes, so it's not in much use.

This is the new implementation of how to make platform-safe native keys,
for which no past compatibility is required nor promised. Unlike when we
started in Qt 4.4, it doesn't look there are many restrictions in names
anyway.
Important differences are:
* POSIX RT: no restrictions, we prepend the necessary '/'
* System V/XSI: no restrictions, it's just a file path anyway;
we pass absolute paths unchanged; otherwise we prepend RuntimeLocation
* Windows: no restrictions, but we do recognize Global\ and Local\
kernel objects without munging them
The use of the RuntimeLocation may cause a warning on Unix systems
(other than Apple ones and Android) if $XDG_RUNTIME_DIR isn't set.
We do enforce the Apple 30-character limit here, otherwise you get

Due an incorrect implementation of QDoc, which has now been removed,
with regards to identifying copy/move assignment operators, and the more

to the clang AST, QDoc was unable to report the lack of a binding

As of the latest changes to QDoc this will correctly generate a warning.

Our combined reallocation and resizing function, reallocate_impl(),
runs afoul of this when it uses std::is_copyable in a constexpr-if to
implement resize(n, v) without running into problems with move-only
types: the trait is true, but actual instantation runs into a
static_assert in the STL implementation.
To fix, move the problematic resize functionality out of
reallocate_impl() and into the resp. resize_impl overloads. The shrink
functionality remains in reallocate_impl(), because there are many
more users, and it only requires destructible<T>, which isn't
constraining at all.

QDir caches data in mutable variables. Because of no protection, two
threads calling for instance QDir::count on two independent but shared
copies of a QDir object caused a data race.
Running the tst_QDir_tree and tst_QDir_10000 three times with and
without this change show no change beyond the difference between
each result. For instance tst_QDir_tree::thousandFiles:"src" took
36/35/37 ms before the change and 35/35/35 ms after.
This makes sense because the time to handle mutexes is very little

The typed permission classes' properties, insofar as they have any,

QLocationPermission implements it that way, but these two typed

was fixed in an earlier commit. However, default values of properties
are most natural when they're equal to the default-constructed value
of the property's type, and this was no longer the case for
isReadOnly.
By renaming the property to isReadWrite, defaulting to false, this
relationship is restored, and code using the classes looks more
natural:

To support cancellation of continuations attached via the parent future,
we store a pointer to continuation future's data in parent. This
requires preserving the lifetime of continuation future's data while the
parent is still alive (see 24dedaeaa1).
This is achieved by capturing the promise in the continuation's lambda,
which is only cleaned up after the parent's data is destroyed. This is
already the case for continuations without context, but was overlooked
for continuations with context: they transfer the ownership of the
continuation promise to lambda passed to QMetaObject::invokeMethod(),
which destroys the lambda's context after it's run. As a result, the
continuation's promise (and data, if there are no other copies of it)
is also destroyed, leaving the parent pointing to deleted continuation
data.
To fix this, capture a copy of continuation future's ref-counted data in
the continuation's lambda. This will guarantee that the continuation
data remains alive until the parent is destroyed and the continuation
is cleaned up.

There are two ways to override whether shortcuts (key sequences) should
be shown in menus, QStyleHints::::showShortcutsInContextMenus() and
the Qt::AA_DontShowShortcutsInContextMenus application attribute,
but only the latter is checked by our own menu implementations.
This was confusing, as overriding the style hint had no effect.
It makes sense for the QStyleHint to be based on the platform style
hint, but since we also allows overriding it, the logic in QGuiApp
that initializes Qt::AA_DontShowShortcutsInContextMenus should be
based on the QStyleHint.
Note that the inverse relationship is not maintained, as the app
attribute should not affect the style hints.
This creates a somewhat awkward situation in terms of when you need
to override the behavior, so we might consider deprecating one of
the options.

If a type is trivially default constructible, QMetaType (and QVariant)
think that it can be built and value-initialized by zero-filling a
region of storage and then "blessing" that storage as an actual instance
of the type to build. This is done as an optimization.
This doesn't work for all trivially constructible types. For instance,
on the Itanium C++ ABI, pointers to data members are actually
value-initialized (= zero-initialized, = initialized to null) with the
value -1:
https://itanium-cxx-abi.github.io/cxx-abi/abi.html#data-member-pointers
This means that a type like
struct A { int A::*ptr; };
is trivially constructible, but its value initialization is not
equivalent to zero-filling its storage.
Since C++ does not offer a type trait we can use for the detection that
we want to do here, and since we have also decided that Q_PRIMITIVE_TYPE
isn't that trait (it just means trivially copyable / destructible), I'm
rolling out a custom type trait for the purpose.
This type trait is private for the moment being (there's no
Q_DECLARE_TYPEINFO for it), and limited to the subset of scalar types
that we know can be value-initialized by memset(0) into their storage
(basically, all of them, except for pointers to data members).
The fix tries to keep the pre-existing semantics of
`QMetaType::NeedsConstruction`. Before, the flag was set for types which
were not trivially default constructible. That included types that
aren't default constructible, or types that cannot do so trivially.
I've left that meaning unchanged, and simply amended the "trivial" part
with the custom trait. A fix there (to clarify the semantics) can be
done as a separate change.

The QAndroidApplication::runOnAndroidMainThread() function creates a
task on QThreadPool::globalInstance() to wait for a timeout and cancel
the QFuture representing the task.
It does so by passing a lambda to QThreadPool::start(std::function)
that captures the future, a local variable, by reference. This is UB
when the lambda is ever executed, because the local stack variable's
lifetime will have ended.
To fix, simply capture the future by value, not by reference. Since
QFuture::cancel() is not const, we need to make the lambda mutable.
