Use the libavutil vdpau frame allocation code instead of our own "old" code. This also uses its code for copying a video surface to normal memory (used by vdpau-copy). Since vdpau doesn't really have an internal pixel format, 4:2:0 can be accessed as both nv12 and yuv420p - and libavutil prefers to report yuv420p. The OpenGL interop has to be adjusted accordingly. Preemption is a potential problem, but it doesn't break it more than it already is. This requires a bug fix to FFmpeg's vdpau code, or vdpau-copy (as well as taking screenshots) will fail. Libav has fixed this bug ages ago.
