The responsibility of sendWindowSystemEvents() is to process events from
the window system. Historially that logic was part of the QPA/QWS event
dispatcher, which naturally also sent posted events. Through refactoring,
the code at some point ended up in in the QWindowSystemInterface class,
still with the posting of events in place.
This resulted in QPA event dispatchers adopting a pattern of just calling
sendWindowSystemEvents(), as that would cover both posted and window system
events. Other event dispatchers would call sendWindowSystemEvents(), and
then use a base-class implementation from QtCore for processing events,
resulting in two calls to QCoreApplication::sendPostedEvents() per
iteration of processEvents(). This breaks the contract that processEvents
will only process posted events that has been queued up until then.
We fix this entanglement by removing the sendPostedEvents() call from
QWindowSystemInterface::sendWindowSystemEvents() and move it to the
respective event dispatchers. For some EDs it means an explicit call
to sendPostedEvents, while others were already doing sendPostedEvents
though a separate source (GLib), or using a base-class (UNIX/BB), and
did not need an extra call.
We still keep the ordering of the original sendWindowSystemEvents()
function of first sending posted events, and then processing any
window system events.

As we're using CFRunLoopIsWaiting() to check for the possible presence
of system events hasPendingEvents() will never return false if called
on the main thread. We assume clients will not use this function to
determine whether or not to call processEvents(), but instead use the
return value from processEvents.

UIKit changes the run-loop mode during scrolling to UITrackingMode, which
presumably prioritizes touch events and other sources related to a
smooth scrolling experience. It signals this change by interrupting the
current run-loop pass, and the outer loop is responsible for re-entering
the run-loop in the new mode. Failing to enter the run-loop with this
new mode results in UIScrollViews losing their kinetic feel when
flicking. This can be observed by e.g. bringing up the Emoji keyboard
and scrolling it horizontally.
We keep track of the current run-loop mode by listening for push and pop
notifications on the UIApplication object. The current mode is then used
in our Q_FOREVER-loop when re-entering CFRunLoopRunInMode.
For now we don't add our posted event source or timer source to the
new modes, under the assumption that the system prefers to limit the
number of sources that will fire during scrolling. If this turns out
to give a bad user-experience for Qt applications we should consider
changing it.

Instead of having separate code-paths for QEventLoop::EventLoopExec
and the non-blocking processEvent() we now have a single Q_FOREVER
loop where the logic can be shared. We make multiple loop-passes,
each time calling CFRunLoopRunInMode with potentially different
arguments, depending on the result of the previous run.
For the EventLoopExec case we'll continue making loop-passes until
the event-loop has been interrupted. For the non-EventLoopExec case,
we respect interruption, but will continue making loop-passes only
until we've processed all events in the queue, optionally waiting
for the initial event if WaitForMoreEvents is set. Limitations in
the CoreFoundation APIs unfortunately force us to keep some state
on whether or not we've processed events and timers for a given
processEvents() pass (with corresponding deferred scheduling of
timers and event source signaling).
The way we handle timers has also been rewritten to no longer defer
the timer activation to a special timer source. The constraint of
CoreFoundation timers is that they can not recurse (re-fire) in a
callback, but that only applies per timer, so using multiple CF
timers allows us to recurse. We still only use a single CF timer
for all the Qt timers though, and only spawn a new CF timer if
the user calls processEvents() inside a timer callback.
This commit removes the logic related to dealing with UITrackingMode,
as that logic was slighly problematic, but the feature will be
added back in a follow-up commit, in line with the new approach.
The result of this commit is that we're passing all event-loop,
event-dispatcher, and timer auto-tests, both for the QtCore dispatcher
and the GUI event-dispatcher.

This approach follows the same one used by the Cocoa event dispatcher.

Now that it lives in QPlatformSupport, will be fleshed out more, and
might be used on OSX at some point in time. Still iOS specific, as
none of the iOS API usages have been ifdef'ed.
