The existing overload unconditionally copies the QVariant, causing it
to unconditional detach in most cases (when calling data() later).
The rvalue overload need not preserve the source object, so doesn't
need to copy.
Implement the lvalue overload in terms of the rvalue one, but keep the
sanity check in both to avoid copying the QVariant just to find that
there's nothing to do.
Following the copy, there were some references to the source object,
but they can all be replaced by references to the target object
instead, which hasn't been touched by then, yet.

On macOS, swiping with a single finger on the track pad (which Qt
identifies as a QInputDevice::DeviceType::TouchPad) results in a
TouchBegin event. For widgets that accept touch events (perhaps
implicitly because they want pan gestures, like QGraphicsView),
this results in a TouchBegin event to be delivered.
QApplication::notify will then check the widget's focus policy, and with
ClickFocus set, will set focus on the widget.
This is not what we want for a TouchBegin on a touch pad, so skip the

In Qt >= 6.1, < 6.5, a trivially constructible type would have the
NeedsDestruction flag set, but it's dtor pointer would have been null.
In Qt 6.5, the meaning of the NeedsDestruction flag was changed to be
more aligned with what the name suggests, and thus would only be set for
non-trivially destructible types. For QMetaType this was fine, but
QVariant has a check for acceptable metatypes which attempts to verify
whether a QMetaType is usable for QVariant. The check assumes the
semantics of Qt 6.5, and thus fails for metatypes created by older Qt
versions.
To fix this issue, we increment the QMetaType revision field, and only
check the metatype's destruction support if the revision is high enough.
In theory, that allows passing unsuitable metatypes from older Qt
versions to QVariant; however, such code would have been broken in prior
Qt releases already (which didn't attempt the check), and no code that
used to work in any released Qt version will break (as we simply skip a
check that was passing before).

To fix the broken sliders reported in QTBUG-98093 a workaround was
added by 4bee9cdc0a where we would
call initWithFrame on an already initialized NSSlider.
This breaks the contract of object initialization in Objective-C,
as the class is free to allocate and prepare resources for the
instance without freeing previously acquired resources first.
As noted by the Object Initialization chapter of the Concepts
in Objective-C Programming guide, "Once an object is initialized,
you should not initialize it again.":
https://tinyurl.com/objc-object-init
And as observed in QTBUG-112899, the additional initialization
resulted in a memory leak.
The other part of 4bee9cdc0a
was that we now called startTrackingAt twice when drawing.
Both from setupSlider, for all consumers, and from
drawComplexControl, and as it turns out, this is the key
thing that "fixes" the pressed knob drawing of NSSlider.
For some reason, NSSlider needs the duplicate startTrackingAt
call both to draw the knob as pressed, and to not let one
drawing pass affect another drawing pass. This would benefit
from further investigation, but for now the removed leak
is an improvement.

On systems with weak memory ordering, it was possible for the

loadRelaxed() without observing the contents of the object itself. The
mutex *does* release the contents of the object to memory, but without
the corresponding mutex acquisition, we couldn't guarantee that the
object's contents would be observed. Now we can.
We don't need to fix the load inside the mutex because the mutex will
have acquired everything from either a previous call to pointer() or to
reset(). The store inside reset() need not be storeRelease() either
because the effect of observing the Uninitialized state will be to lock
the mutex.
None of this is used to protect the data as it is being mutated by the
user in multiple threads, or their access simultaneously with reset()
(which is why the load outside the mutex was removed).

Functions in Qt that take a callback need to support callables with or
without context objects, and member functions of an object. The
implementation of those overloads follows a pattern that ultimately
results in a QSlotObjectBase implementation being created and
passed to an implementation helper that takes care of the logic.
Factor that common pattern into a new helper template in QtPrivate
that returns a suitable QSlotObjectBase after checking that the
functor is compatible with the specified argument types.
Use that new helper template in the implementation of
QCoreApplication::requestPermission and QHostInfo::lookupHost.
The only disadvantage of centralizing this logic is that we cannot print
a more detailed error message indicating which argument types the
caller expects. However, that information is visible from the detailed
compiler errors anyway.

Problem: "ninja clean" does not fully clean the build directories of
configure-time executables (e.g. syncqt). This can lead to problems when
building with compiler and linker launchers: on configure time, the
launchers are not used (compare CMake issue #20762). After a "ninja
clean", the executable might be removed but the object files are still
there. This leads to a situation where the object files have been
created without the compiler launcher but are linked with the linker
launcher. We encountered a situation however, where the linker launcher
requires the usage of the compiler launcher.
The configure-time executable has a ${target}_build custom command that
runs "cmake --build" and creates a timestamp file to track when to build
the target. To circumvent the problem of stale object files we add the
"--clean-first" argument to that target to fully rebuild configure-time
executables if the timestamp file is out of date.
The performance this imposes is negligible, because
1. Those configure-time executables are seldom out of date.
2. They are supposed to be "tiny executables with system dependencies
only" anyway.
