The test started to fail on my system without changing anything. I
assume my system got an update to latest wayland version and it
looks like the registry doesn't announce anything if nothing is
registered. So now our display at least creates the Shm interface.
In addition the test case is slightly improved with a few smaller
changes added during the debug session.
The EventQueue is a wrapper for wl_event_queue. The usage is for the
case that the connection is in a different thread.
The EventQueue needs to be added to the Registry before Registry::create
is invoked. This ensures that the Registry gets added to the EventQueue
and all objects created by the Registry (and further down the tree)
will be added to the same EventQueue.
The auto-tests which already used a wl_event_queue are transited to the
EventQueue class. That's also the reason why there is no dedicated
unit test: the new code is sufficiently tested by the existing tests.
Framework style build system which generates two libraries:
* KF5WaylandClient
* KF5WaylandServer
autotests are adjusted to compile again. They need to be changed to
use the libraries once the export header gets generated.
