vdpau: presentation queue video output display plugin

This uses a VDPAU presentation queue to render VDPAU output surfaces
(i.e. screen-scaled RGBA pictures) on an X11 window. It is assumed that
a video filter will eventually convert pictures in the source video
format to VDPAU output surfaces of adequate dimensions.

The common VLC XCB event handling is used for X11 matters.
