vo_opengl: add experimental vdpauglx backend
As the manpage says, this has no value other than adding bugs. It uses code based on context_x11.c, and basically does very stripped down context creation (no alpha support etc.). It uses vdpau for display, and maps vdpau output surfaces as FBOs to render into them. This might be good to experiment with asynchronous presentation. For now, it presents synchronously, with a 4 frame delay (which should whack off A/V sync). The forced 4 frame delay is probably also why interaction feels slower. There are some weird vdpau errors on resizing and uninit. No idea what causes them.
