lavc/hevc_ps: Add SPS/PPS parse support for HEVC extension syntax 1. Add extension syntax according to 7.3.2.2.3/7.3.2.3.3 in T-REC-H.265-201911. 2. Keep using parsed PPS when bitstream overread for compatibility. For example, the clip PS_A_VIDYO_3.bit in FATE test has incomplete extension syntax which will be overread and un-decodable if without this change. 3. Format brace in pps_range_extensions().

avcodec/hevc_ps: Use RefStruct API for parameter sets Avoids allocations and error checks for these allocations; e.g. syncing buffers across threads can't fail any more and needn't be checked. It also gets rid of casts and indirections. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
