This change implements support for white listed global shortcuts in
the lock screen. It interacts with KGlobalAccel to fetch shortcuts
and checks them when a key is pressed. For more detailed information
on how this functions, please see the documentation added to the new
file globalacel.h.
So far only shortcuts from kmix are white listed. This allows to
mute and change volume while the screen is locked.

XFlush is not called automatically when going back to event loop, thus
events are not delivered. With the XFlushs at these two positions I'm
no longer able to reproduce the problem that the screen ends up black
instead of showing the lock windows.
The screenlocker_greet needs to tell the parent ksld process which
windows it created. Ksld sends input events to these windows. So
far this was based on an X property on the window. Unfortunately
ksld didn't validate whether the windows tagged with this property
belong to the screenlocker_greet process it started.
With this change the communication for announcing windows is moved
away from the X11 protocol and instead a custom Wayland protocol is
used.
Ksld starts a KWaylandServer when the greet process gets started. It
creates anonymous unix sockets for the connection and passes one
filedescriptor to the started greeter process.
The check for the X property is removed in ksld and instead only
windows ids passed through the Wayland socket connection are
accepted.

The LockWindow deep called into KSLDApp to unlock in case of user
activity during grace time. But LockWindow also emits a signal on user
activity. From an architectural point of view it's better to handle this
directly in the KSLDApp and connect to the signal to unlock if it's in
grace time.
Another advantage is that LockWindow now no longer pulls in the KSLDApp
which improves the unit test situation for the LockWindow as the
lockWindowTest no longer needs to link the complete ksld library.
