0739cfc209 added the draw_frame API
deprecated draw_image internally. VOs that still used draw_image were
around, but really there's no reason to not just "upgrade" them anyway.
draw_frame is what the "real" VOs that people care about (gpu/gpu-next)
use. So we can just simplfy the code a bit now. VOCTRL_REDRAW_FRAME is
also no longer needed so that can be completely deleted as well. Note
that several of these VOs are legacy crap anyway (e.g. vaapi) and maybe
should just be deleted but whatever. vo_direct3d was also completely
untested (not that anyone should ever use it).
