The old logic didn't care to listen for wl_buffer.release events
so it always drew in the same buffer, potentially resulting in
tearing if the compositor was scanning out the buffer at the same time.
Instead properly cycle between a few buffers and don't reuse the same
one until the release event was received.
The old code also used to throttle the redraws, unless the buffer was
changing, that is unless the window was getting resized. This is now
lost, and no throttling is ever done. Doing it properly, by waiting
for the frame callback before committing the new buffer shows very
noticeable lags with many applications when resizing, because they
paint many times per resize event, so they fall behind the cursor.
A proper fix will be to implement the support for requestUpdate(),
and using it in the applications.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

There currently is a QWaylandInputDevice class both in the wayland QPA
plugin and in the QtCompositor API. This causes the qwindow-compositor
example to crash when running nested in a wayland session due to a
mismatch between the two classes.
By namespacing all the plugin code we make sure that name clashes
will not happen anymore.

There was a race condition between the gui and the wayland event thread
which could lead to double freeing the QWaylandShmBackingStore's frame
callback. Protect the wl_callback_destroy calls using a mutex.

Wayland 1.2 added support for display scaling, where wl_output
has a "scale" event informing the the client that the compositor
will scale the output surfaces by the given factor. The client
then has the option of providing large surfaces to match the
target pixel densety and bypass the compositor's scaling. This
is done by calling wl_surface::set_buffer_scale.
Re-use the current high-dpi support in Qt by implementing
devicePixelRatio() for QWaylandScreen and QWaylandWindow.
Provide high resolution buffers both for raster and OpenGL
graphics.
Introduce a new coordinate system: buffer coordinates, which
is related to the window coordinate system via an "int scale"
scale factor. This scale factor corresponds to Qts qreal
devicePixelRatio, but we keep the name and the type in the
QtWayland implementation.

QWaylandShmBackingStore installs a frame callback on flush, and subsequent
flushes will not attach a new buffer until the callback is fired.
If the window is hidden while we're waiting for the callback, we attach
a NULL buffer, so the compositor will not redraw the surface and will not
fire the frame callback. When showing the window again the backing store's
flush() will wait indefinitely for the frame callback to attach its buffer.
To fix it destroy the frame callback when the window is hidden.
This was easily noticeable when fast switching between popup menus.

In an attempt to make QOpenGLWidget and QQuickWidget working on Wayland.
Since Qt 5.3 all widget windows are of type RasterGLSurface (given that
the plugin reports this capability which wayland will, with this patch).
Such a window can behave either like a raster or an OpenGL window.
This concept maps badly to platform plugins that have a rigid separation
between raster and OpenGL platform window implementations. From now on,
the OpenGL window implementation, that is used pretty much always,
except for raw RasterSurface windows, must be prepared to behave like
a raster window too, which involves having a backingstore.
