GstVaapiPixmap is an abstract base class which only implementation
were GstVaapiPixmapX11. This class were used for a special type of
rendering in the tests apps, utterly unrelated in GStreamer.
Since gstreamer-vaapi is no longer a general-user wrapper for VA-API
we should remove this unused API.
This removal drops libxrender dependency.
FEI encoders are not actively mantained neither tested, and it is
using infrastructure that is changing and FEI is stopping this
effort.
Also it is required to rethink how FEI can be used in GStreamer.
The context overlay was an optimization to apply a video composition
to all the surfaces bound to a context.
But since commit 18031dc6 this optimization was disabled, so it is
better just get rid of it.
[wl_shell] is officially [deprecated], so provide support for the
XDG-shell protocol should be provided by all desktop-like compositors.
(In case they don't, we can of course fall back to wl_shell).
Note that the XML file is directly provided by the `wayland-protocols`
dependency and generates the protocol marshalling code.

Since there is duplicated code in h264/265 encoder, we could
refactor it to avoid duplicated code.
