0d83fcc07b lavc/hevc_ps: parse constraint flags for HEVC REXT 
Parse all the constraint flags according to ITU-T Rec. H.265 (02/2018).

They have to be passed to hw decoders to determine the exact profile for Range
Extension HEVC.

80e1c93c87 avcodec/hevc_ps: Remove dead code in vps_id check 
Since reading 4 bits always returns a value in the range [0, 15], the
check for vps_id >= HEVC_MAX_VPS_COUNT, where HEVC_MAX_VPS_COUNT = 16, is redundant.

f4ea930a11 avcodec/hevc_ps: Expose all SPS and PPS range extension flags 
We need all the flags to be exposed to be able to pass them on to
HW decoders. I did not attempt to nuance any of the warnings about
flags being unsupported as there's no way, at the point we extract
flags, to say whether an HW decoder is being used.
