Summary:
Mostly intended for plugins loaded into KWin and wanting to use
KWayland::Client::ConnectionThread::roundtrip(). By providing this
function we can ensure that KWin does not block and nevertheless
perform the required roundtrip.

This introduces an own QPA plugin for KWin. QtWayland's plugin is not
a good solution for KWin as QtWayland is meant for Wayland clients and
not for a Wayland server. Given that it makes more sense to have a very
minimal QPA plugin which supports the use cases we actually have.
With our own QPA plugin we should be able to improve the following
areas:
* no need to create Wayland server before QApplication
* Qt::BypassWindowManagerHint can be supported
* no workaround for creating OpenGL context in main thread
* sharing OpenGL context with Qt
* OpenGL context for Qt on libhybris backend
The plugin supports so far the following features:
* creating a QPlatformWindow using KWayland::Client (ShellSurface)
* creating a QPlatformBackingStore using a ShmPool
* creating a QPlatformOpenGLContext with Wayland::EGL
* or creating a QPlatformOpenGLContext which shares with KWin's scene
* creating a QPlatformScreen for each KWayland::Client::Output
* QPlatformNativeInterface compatible to QtWayland
The aim is to be able to create a plugin for each of the backends.
The following directories are created:
* backends/drm
* backends/fbdev
* backends/wayland
* backends/x11
This new backend allows to start a kwin_wayland server nested on an
X-Server by using a normal X11 window as output. This allows testing
kwin_wayland without needing to start another Wayland server first.
The behavior is triggered by using new command line arguments:
--windowed
--x11-display=<:0>
With optional --width and --height arguments.
In this mode the WaylandBackend is not created at all.
So far the backend is not fully integrated yet and only the QPainter
backend supports this mode.
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.
