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.

The WaitForMoreEvents flag only guarantees that we will process _some_
events -- either if they are in the event queue already, or by sleeping
and then waking up to process an event. This event might be a system
event, not the timer firing, so a single call to processEvents() is
not enough to guarantee that the timer has fired. Instead we do a
Q_COMPARE with a timeout, where we continiously process events until
we see that the timer fired.

Since Qt5, the QMetaObject do not contains the string name of the
builtin types, but only the QMetaType id. QMetaMethod::typeName
convert back from the id to the string. But if the type is aliased,
the string of the main type is returned.
This was the case for example for qint64 which is transformed to
"qlonglong".
This causes a regression in QMetaType::invoke when trying to invoke a
method which return an aliased type, since the string comparison would
fail.
Fix the problem by also comparing the metatype id.

In QML it is common to connect signals to slots that are implemented as
JavaScript functions. QML used to maintain separate data structures that
mirrored the QObject connection list and kept references to the JavaScript
objects necessary to perform the call on signal activation.
The recent addition of functor based QObject::connect makes it possible
to store this information in QSlotObjectBase sub-class instead, which
eliminates any extra bookkeeping.
This patch adds internal connect and disconnect overloads to QObjectPrivate
that allow for connecting QObject *sender, int signalIndex to a given
QSlotObjectBase and similar for disconnect.
