If we were on e.g. vt 1 and pressed Ctrl+Alt+F1 KWin broke as it
disabled rendering for vt switch and vt switched to vt 1, which
obviously failed.
So let's check whether it's going to switch to the vt we are already
on and ignore surch requests.
Each of the backends becomes a plugin. This allows kwin_wayland to load
the requested plugin and kwin itself doesn't need to link all the
libraries needed. E.g. libdrm is no longer linked if running kwin_x11.
Also this allows to create backends for the non-standard EGL platforms
(examples could be raspberrypi or Android devices).
A new Singleton VirtualTerminal is added. It interacts with Logind to
get the VTNr to take over. To get the signal to release and acquire the
VT we use a signalfd with a QSocketNotifier to monitor for signals. The
used signals must be blocked for all threads prior to startup otherwise
they are delivered to secondary threads causing issues.
The AbstractBackend provides a virtual method to create the Screens.
A concrete backend can implement this method to create the backend
specific Screens instance.
This removes the casting logic from Screens::create.
The AbstractBackend registers itself in the WaylandServer allowing
external users to easily get to the backend and not needing to test
manually which backend is used.
Xcb::GeometryHints is a convenient wrapper around the size hints
as described in ICCCM combined with the sanity checks so far applied
by KWin after reading the property.
Instead of accessing the members of the property structure, we are
now using the convenience methods.
During ::manage no further actions are triggered when reading the
size hints. Only when they are read later on the previous checks
are applied. During ::manage they can be ignored as it had a dedicated
isManaged check.
The method ::resizeWithCheck got a new argument of type xcb_gravity_t
which defaults to 0. This is needed from ::configureRequest which so
far temporarily changed the xSizeHints structure. By passing as an
argument this is no longer needed.

being v2+ (right now it says just GPL, which according to GPL itself
means any GPL). Decoration clients will come later.

"We strongly recommend that all subclasses of QObject use the Q_OBJECT macro regardless of whether they actually use signals, slots and properties or not."

enabled by default, but will be made configurable soon. There is a known
issue with an incorrect geometry shown with konsole, but that's its fault,
and I'll get to that shortly (xterm does the right thing).
Disclaimer:
If it jams - force it. If it breaks, it probably needed replacing anyway.
