VAAPI-XCB: rewrite Surface handling.

The surface handling has been rewritten to be more consistent and to
avoid reusing surfaces that are still in use by the display thread. Some
VAAPI wrapper drivers use the DirectSurface mode, meaning that the surface
handed by the application is used directly for displaying. It does not
copy the surface into a display surface. When the driver does this, then
you cannot reuse this surface which is being displayed for rendering the
next picture too
