#8593: Add VA API support

Comment(by markk):
I noticed several discussions on VA API support so I thought I'd better
post what I have to date.
Version 1 has been tested with the Splitted Desktop VDPAU backend using an
NVIDIA GeForce 210. Decoding works and video does appear on screen.
Issues/Outstanding features
- the configure changes are wrong/incomplete
- video presentation is a complete hack as I have been unable to get the
GLX driver support working to copy the decoded surfaces to a GL texture.
Hence there is no OSD etc
- Live tv does not work - though I think the problem may actually be
related to the OSD port merge.
- handling of unsupported profiles may well be buggy and in combination
with video renderer fallback behaviour may well be a sizeable problem.
- the approach of sub-classing VideoOutputOpenGL may not work - though the
alternatives are potentially messier.
