The QWeakPointer conversion SMFs cannot actually be used for QObject
payloads, as, for unknown reasons (some comment about vtable this
author doesn't understand), conversion goes through QSharedPointer,
the creation of which throws the checkQObjectShared() warning and
yields a nullptr.
We need to continue to use the QWeakPointer(T*, bool) constructor the
QPointer(T*) ctor also uses.
It's high time we dissociated QPointer from QWeakPointer...

The constructor's documentation already had the note saying that we
could apply this optimization, but it wasn't there and looks like it
never was. This only applies to the default constructor, which sets t1
to zero, which is the epoch. This could be a problem for an OS whose
monotonic clock starts with negative values, but I don't know such an OS
exists and this hasn't been a problem so far.
This commit doesn't change the behavior of the old-style, non-
std::chrono getters, because we always transform any negative remaining
time to 0. It is only possible to observe it by asking the remaining
time or the deadline using the std::chrono API.

As part of ed2b110b6a the implicit caching

We now cache the most critical of these, the zero digit, in the Darwin

restoring the performance two orders of a magnitude closer to that of Qt 5.

The reason this worked before is unclear. It could be suspected
that we have made a dpi awareness change or Microsoft changed
the behavior of the OpenThemeData function.
Regardless, we expect the result to match the primary display which
OpenThemeData doesn't do (anymore). Instead it returns a value based on
the hwnd screen (which btw didn't always match the widget) and the cache
system would then re-use that theme also for hwnds on other screens.
The most obvious solution is to use OpenThemeDataForDpi to make sure
we get a theme result matching the primary sceen. Then our correction
of the result by with multiplying
QWindowsStylePrivate::nativeMetricScaleFactor(widget)
works again.
This fix does not only fix QMenu sizes. It fixes the size for all
widgets that use this theme function, which could return near
random results before.

If the event dispatcher is interrupted we propagate the interrupt to
lower event loop levels, in case they too need to be interrupted. And
we defer the actual interrupt of the NSApplication to the next time we
process Qt events, to avoid AppKit dropping queued events on the floor.
This logic relies on QCocoaEventDispatcher::processEvents() setting the
interrupt flag to false, which signals that we should not continue to
tear down any further event loops.
Unfortunately, native run loops such as running application modal
sessions, are not driven by QCocoaEventDispatcher::processEvents(),
so we never reset the interrupt, and end up ending the session
immediately.
To work around this we need to explicitly clear the interrupt flag
before starting native modal sessions. This also fixes the issue
seen in QTBUG-111524 with showing native alerts from nested event
loops.

SetupDiOpenDeviceInterfaceW and then extracting the corresponding blob
from the Registry through a key handle retrieved with
SetupDiOpenDevRegKey. This blob can be parsed just like in Linux with
the QEdidParser class. The resulting metadata is applied to
the WindowsScreenData instance.
Additionally, this commit implements support for clone groups by making

and the EDID manufacturer, model and serialNumber properties.

QDateTimeParser::fromString(), when parsing a date-time, uses the
start of 1900, in local time, as its default date-time. (This is a bad
choice and steadily getting worse.) This turns out to be somewhat
expensive for some client code, so make it a static const so that we
only compute it on the first call, as for getM{in,ax}imum().
The potential downside is that a change to system time zone won't be
reflected in this value. However, any sane parse-format should require
over-writing all fields of this initial value, in any case, so the
issue is less severe for this default value than for the existing
getM{in,ax}imum() statics.

As described in 3bedeb837e, the way
menu items on macOS are typically set up they have an action, e.g.
copy:, but no target, and the system then takes care of finding the
right target at runtime, starting with the first responder, walking
the responder chain, and then moving on to other NSWindows, before
ending up in the NSApplication and its delegate.
As we (still) don't have a mechanism in Qt to forward generic
actions, such as the cut/copy/paste, or selectAll, so we rely on
mapping the actions back to QCocoaNSMenuItem that we can trace
back to a QPlatformMenuItem that we in turn emit activated() for.
Normally this works fine, but in the case where the Qt app is embedded
in a native UI, which has its own menu items with cut/copy/paste,
we'll get callbacks into QNSView for actions triggered by a generic
NSMenuItem.
In that case, we need to bail out, but we want to do so in a way
that lets AppKit continue to walk the responder chain. This is
possible by implementing supplementalTargetForAction:sender:,
where we have access to the sender. If sender doesn't match
the expected QCocoaNSMenuItem we let AppKit find a better match
up the chain.
Since the target we return needs to ultimately respond to the
selectors and/or forward them, we can't point the target back
to ourselves, nor can we point it to the application delegate
directly, as the menu items need to be validated in the context
of the view, so a new per-view QNSViewMenuHelper class has been
added to take the role of forwarding the menu actions.
The logic for forwarding the resulting actions to the application
delegate has been simplified and hardened a bit as well.
A possible scenario with this new approach is that the Qt app
has a line edit focused, and the user tries to activate the
menu item for Paste, but the item is grayed out because we
can not support the action. This is of course confusing for
the user, but less so than having an active menu item that
then doesn't do anything when activated.
Another scenario is that a responder later in the chain does
respond to the paste action, and the menu item will end up
pasting into something that is not the first responder.
This might also be confusing for the user, but it's generally
recommended that implementers of actions like paste only
allow the action if the view is the first responder, and
this is something views have to deal with anyways, so it
doesn't change anything that we're now bailing out earlier
in not accepting the paste.
One benefit of allowing AppKit to find a better target for the
action is that if no target is found, and the user presses the
key equivalent of the disabled menu item, the key event will
be delivered as a normal keyDown to our QNSView, which we do
forward, allowing the Qt app to respond to the action, even
though the action came from a generic menu item. With our old
approach this would not happen, as we would claim to support
the action for our QNSView, but then drop it on the floor when
AppKit tried to deliver it to us.

The testAndSet operation is expensive if the lock is contended:
attempting to CAS that lock will cause the cacheline containing the lock
to be brought to the current CPU's most local cache in exclusive mode,
which in turn causes the CPU that has the lock to stall when it attempts
to release it. That's not desirable if we were just trying an untimed
tryLock*.
In the case of timed, contended tryLocks or unconditional locks, we
still need to perform an atomic operation to indicate we're about to
wait. For that case, this patch reduces the minimum number of atomic
operations from 2 to 1, which is a gain even in the case where no other
thread has changed the lock status at all. In case they have, either by
more threads attempting to lock or by the one that has the lock
unlocking it, this avoids the cacheline bouncing around between the
multiple CPUs between those two atomic operations. For QMutex, that
second atomic is a fetchAndStore, not testAndSet.
The above explanation is valid for architectures with Compare-And-Swap
instructions, such as x86 and ARMv8.1. For architectures using Load
Linked/Store Conditional instructions, the explanation doesn't apply but
the benefits still should because we avoid the expense of the LL.
