This patch amends 730cbad8824bcfcb7ab60371a6563cfb6dd5658d
The issue was that the event reader thread (QXcbEventQueue::run()) can enqueue
events sometime between GUI thread has last time peeked at the queue and before
it has called waitForNewEvents() and hence started waiting for more events (via
QWaitCondition). This scenario is even mentioned in the QWaitCondition documentation:
"[..] if some of the threads are still in do_something() when the key is pressed,
they won't be woken up (since they're not waiting on the condition variable) and
so the task will not be performed for that key press. [..]"
And if there are no more events on the X11 connection, the waitForNewEvents()
in QXcbClipboard::waitForClipboardEvent() would timeout.
Fixes: QTBUG-75319

The lags can be seen when dragged data is requested for a
MIME type. This leads to calling QXcbClipboard::waitForClipboardEvent()
which runs a loop in the GUI thread and processes events from
QXcbEventQueue. The loop ends when a corresponding event is
received, otherwise it makes a delay of 50 ms before the next
iteration.
Sync with QXcbEventQueue thread by QWaitCondition instead
of using the delay. This way the loop will end as soon as
possible and Expose events will be processed with minimal
delay.

This will be the only options for Qt 6, so make sure the code compiles now.

A basic base class that creates a connection and initializes
extensions. The goal was to reduce the size of qxcbconnection.h/cpp.
Made QXcbAtom into a class that handles atom initialization and
exposes the relevant APIs. Before this patch, all of that logic
was inside of qxcbconnection.h/cpp.

This was a regression from Qt 4.
Before this patch, we supported filtering events only at QWindowSystemInterface
level, but to properly support filtering in QAbstractEventDispatcher::filterNativeEvent,
we have to filter the events earlier. Now it is possible to enable/disable this
feature for platforms that support native event filtering.
The mapping of which events are user input events were taken from
QWindowSystemInterfacePrivate::EventType.

This patch reworks 0b1ce5db9e04b4c28713e87306fcea020c3e428b.
Just by looking at the source code it was unclear why is this
signal-and-slot connection necessary. It doesn't do anything on
normal exit - at the time we call dtor of this class,
QCoreApplication::instance() already is nullptr, which means that
no further event processing happens and we never get this signal.
Without digging into git history it may appear that the goal was
to process the remaining events on application exit, which would
be a questionable code by itself.

QAbstractEventDispatcher::wakeUp is a thread-safe method, using
a queued connection to invoke it is wasteful. This type of connection
involves allocating temporary QMetaCallEvent on a heap and locking of
destination thread's post-event queue. In most use cases this is ok,
and really convenient when target method is not thread-safe. But in
this case the existing solution was suboptimal, especially because
the events we are reading can be high frequency.
The solution that we use here is lock-free. There can be only one
time when it might need to wait for the lock, which is upon exiting
the application. If we have entered the critical section in
QXcbEventReader::run(), then the registered post routine (qAddPostRoutine)
will block the QCoreApplication's dtor (this is where dispatcher is
set to 0) until we exit the critical section. We also know when not
to enter the critical section, in case dtor is already running.
With this approach we might need to compete for the lock at most
once, instead of whole application lifetime, which was the case
with the existing code.

It is necessary for QTBUG-69687. The original code processes the xcb
event queue only when new events have arrived, but if we want to do an
event filtering that buffers some events and processes them later based
on set/unset flags (e.g. QEventLoop::ExcludeUserInputEvents), we need
to call processXcbEvents() on every event loop iteration, not only when
new events have arrived from X server.
The required functionality is implemented by having custom event dispatchers,
instead of using the generic ones from QtGenericUnixDispatcher::
createUnixEventDispatcher() / eventdispatcher_support-private. This also
enables for further customizations, as might be necessary by QTBUG-70095.

For details how this works refer to the documentation in the patch.
The follow-up patches will switch to calling processXcbEvents() on every
event loop iteration. With the existing code that would mean frequent
locking of shared data (event queue). Acquiring a lock is fast, but
lock contention isn't. To avoid potential problems, reimplement xcb event
processing to be lock-free. Besides theoretical performance benefits,
this definitally improves code readability in qxcbconnection.cpp. Thanks
to Mikhail Svetkin for questioning the design of the existing code.
