5220b40edd Port from implicit to explicit atomic integer operations
The old code used the implicit conversions from QAtomicInteger<T> to T
and vice versa. The semantics of these differ from the ones std::atomic
uses, so we're going to deprecate these, like we did for load() and
store(), too.

This patch fixex some users of these APIs before we deprecate them.

e36e32c213 QBearerEngine: fix const-correctness of a loop with const-propagating QESDP
The loop iterates over a collection of QExplicitSharedDataPointer, which
traditionally doesn't propagate const. In Qt 6, it will, so prepare the
code for this change, by taking the loop variable by non-const reference.

Since the loop is followed by container.clear(), make it a consume-loop
by looping over qExchange(container, {}).

8da3eea4fb Optimize some atomic counters
Define the static QAtomic at file scope to avoid GCC's pessimisation with
function-static QAtomic (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79561),
and make sure the initial value is 0, so it ends up in BSS, not TEXT.

In QRhi..., don't create a static instance of the wrapper class, use a file-
static atomic, too. This turns the class into a glorified namespace.

Inspired by:
https://codereview.appspot.com/6812076/
Resizing a window larger results in the newly exposed region being invalidated

This can result in the old region no longer updating.
Was added to D3D9.

Improving a fix from Filippo Cucchetto:
https://codereview.qt-project.org/c/qt/qtbase/+/195336
and pushing to D3D11.

ifndef protects against compilation error for WinRT.
Invalidate() should be used only for desktop apps.

5b5e8f78fe NSMenuItem/NSMenu - set the submenu properly
... in case the submenu is set from a slot, attached to the aboutToShow()
signal. Normally, with a 'statically' pre-populated menu, we set 'submenu'
property on a menu item from 'updateItem' callback in our menu delegate.
After that, AppKit calls our delegate's willOpen call back and this is
where we emit 'aboutToShow'. Unfortunately, if an application tries to
create a nested menu 'dynamically' at this point, it never becomes 'submenu'
of the item, since 'updateItem' was already handled at this point.

We catch this case in QCocoaMenuItem and call setAttachedItem if needed.

33f16af307 rhi: metal: Reuse drawable after a frame without a present
The source of this is likely a "window" grab from Qt Quick. Requesting
a new drawable is an error in this case since we do not enqueue a present
for the current one.

0f3f143f6d Fix window shortcuts when a completer popup has focus
The completer popup has focus, making QShortcut direct to it's window
rather than to the window the completer belongs to. As QShortcut handles
the case for Tool windows that have a parent, but doens't do the same
for popups. And they shouldn't be treated the same way, as a context
menu popup for a e.g. text edit should in fact block the text edit's
shortcuts while open.

However, the completer popup is special, in that it explicitly makes the
widget completes for its focusProxy, which is what we can use to fix
this issue.

859eb2467d Add qmake config for controlling LTCG behavior for static libs
Static libraries may get installed and used by other builds, which may
be done with a different version or build of the compiler. So this
commit introduces two new flags:
 - no-static-ltcg: disables LTCG completely for static libraries
 - fat-static-lto: forces static libraries to produce fat LTO objects

fat-static-lto is useful for Linux distributions, since installed static
libraries should not carry LTO information, but that information is
useful during Qt's own build. This feature should be used alongside some
compiler-specific method of removing the LTO information from the
static libraries prior to installation, so only the regular part
remains.

For current GCC versions, this command suffices:
  strip -R '.gnu.lto*' -R '.gnu.debuglto*' libname.a

Otherwise, distributions can use "no-static-ltcg" to disable it
completely.

cbdc9a7786 RCC: Change the default compression to Zlib
Codebases using QResource::isCompressed() and assuming it is Zlib break
if zstd is enabled. So change the default back to Zlib until Qt 6.0.

[ChangeLog][Important Behavior Changes] RCC's default compression
algorithm was changed back to Zlib, as it was in all previous releases
until 5.13.0. The default will remain Zlib for all Qt 5.x releases but
will change in Qt 6.0. To activate Zstd compression for your resources,
either pass the --compress-algo=zstd option to the rcc tool or add the
XML attribute compression-algorithm="zstd" to the <file> tags in the
.qrc file.
