b012bd5068 libavcodec/x265: detect csps in libx265_encode_init_csp() 
Without this change, if you link with an 8bit libx265 and try to specify
a 10bit input color space via:

  ffmpeg -i in.mov -c:v libx265 -pix_fmt yuv420p10le out.mp4

It will error with:

  Incompatible pixel format 'yuv420p10le' for codec 'libx265',
  auto-selecting format 'yuv420p'

With this fix, it will learn if a 10bit libx265 is available at startup,
and thus allow 10bit input color spaces.

900e3af857 vp9: match another find_ref_mvs() bug in libvpx. 
If we find a second non-sub8x8 motion vector for a non-first sub8x8
block, and the clamped value is identical to the first non-sub8x8
motion vector, then the resulting nearmv motion vector is forced to
zero.

32b6d31ef3 vp9: don't allow compound references if error_resilience is enabled. 
libvpx (probably accidentally) clears the bits if error_res is set,
along with keyframe/intraonly. This probably wasn't the intention
(since it's local data), but it's behaviour we have to copy...
