QWidget does not handle QWindow and QPlatformWindow being destroyed
behind its back, and the QWidget state for internalWinId and the
Qt::WA_WState_Created attribute can easily get out of sync with
reality.
To avoid QWidgetBackingStore mistakenly thinking that a widget does
not have a platform window it can operate on we use the QWindow and
QPlatformWindow handles directly, instead of relying on the winId.
This is a stop gap until we can teach QWidget to deal with dynamic
changes to its underlying window handles.

The array of QAtomicPointer<QMutex> can be initialized using relaxed
stores of nullptr, since nullptr is the whole data. But once we store
an actual QMutex pointer in the array, we need to publish the indirect
data thus created. We did this, with testAndSetRelease(); what was
missing was a corresponding acquire fence on load, without which there
is no happens-before relationship between the writes performed by the
QMutex ctor and the reads performed by a subsequent mutex.lock(), say,
on the same data.
Fix by adding acquire fences to all loads. That includes the dtor,
since mutexes may have been created in different threads, and never
been imported into this_thread before the dtor is running.
As a drive-by, return a new'ed QMutex that was successfully installed
directly to the caller, without again going through a load-acquire.

Lookups performed via QHostInfoRunnable must not synchronously call
the user-code's receiver objects, as that would execute user-code in
the wrong thread. Instead, post a metacall event through the event
loop of the receiver object, or the thread that initiated the lookup.
This was done correctly for the trivial cases of empty host name or
cached results, so the code generally existed. By moving it from a
global function into a member function of QHostInfoResult, we can
simply access the required data to construct and post the event.
As we process that posted event, we need to check that the context
object (which is already guarded via QPointer) is still alive, if
we had one in the first place. If we had one, and it's deleted, then
abort.
[ChangeLog][QtNetwork][QHostInfo] Functors used in the lookupHost
overloads are now called correctly in the thread of the context object.
When used without context object, the thread that initiates the lookup
will run the functor, and is required to run an event loop.

By default Qt tries to avoid potentially costly color matching by
not assigning an sRGB color space to our backingstore, even if
that's what we in practice fill it with.
We used to do this by assigning the display's color space, which
effectively opts out of color matching, similar to the old behavior
of the device RGB color space (which nowadays implies sRGB).
By picking up the color space from the NSWindow instead, we allow
the user to override the color space to trigger color matching,
for example by explicitly setting it to NSColorSpace.sRGBColorSpace.
NSWindow will fall back to the screen's color space if the window
doesn't have one set.

Before that change, each of the three members was a separate

nullptr. Either resourceGlobalData.isDestroyed(), in which case
dereferencing it asserts, or it isn't, in which case resourceList()
returns a valid pointer.
An explicit isDestroyed() check was added to the unregister function,
but the register one was also checking resourceList() for nullptr,
and this was left unprotected.
Add the check and remove the now-tautological checks for nullptr
resourceList().

We also have to properly cache the connection - 'https' or

mixing H2/HTTP/1.1 in a single connection in case an attribute
was missing on a request, which is wrong.
