[FFmpeg-devel,1/2] Add VP9 VDPAU to list of hwaccels and supported formats

Added file vdpau_vp9.c for supporting VDPAU VP9 decoding in FFmpeg with
stub functions. Modified configure to add VDPAU VP9 support. Mapped VP9
profiles to VDPAU VP9 profiles.

Support for VDPAU accelerated VP9 decoding was added with libvdpau-1.3
version. Profiles related to VDPAU VP9 can be found in latest vdpau.h
present in libvdpau-1.3

You also need to update the changelog and the libavcodec version.

This should be added only under AV_PIX_FMT_YUV420P. vdpau doesn't
support 10bit decoding.
