Using VAAPI as a video output (through vaPutSurface) is deprecated and
definitely not recommended for any use case. Since we're starting to
support non-X11 pipelines, remove X11 support altogether.

This VA backend uses v4l2's Frame API proposal to interface with the
"sunxi-cedrus" video driver on Allwinner SoC. Only a few parts of the
code are really dependent on sunxi-cedrus and this VA backend could be
reused for other v4l drivers using the Frame API.
