The AV_INPUT_BUFFER_PADDING_SIZE has been increased to 64, but the value is still 32
in function ff_hevc_sao_edge_filter_8_msa. So, use AV_INPUT_BUFFER_PADDING_SIZE directly.
Also, use MAX_PB_SIZE directly instead of 64. Fate tests passed.

an AVStream that was already in use to be corrupted by assigning it a
new id, which blows up later in mov_read_trun because the
MOVFragmentStreamInfo.index_entry now points OOB.

263b3ad407 avcodec/hevcdec: fix non-ref frame judgement 
After inspecting the source code of x265, mpv and ffmpeg, I've found that
ffmpeg mistakenly regards EVC_NAL_BLA_N_LP and HEVC_NAL_IDR_N_LP as non-
reference frames, which are acutally reference frames according to the
specification in x265, and drops them.

This patch should address the problem. I have tested it with mpv.

dee8f4b01b avcodec/libaomenc: remove AVOption related to frame partitions 
Support for it was apparently never in the codebase, and the enum
value was recently removed from the public headers [1]
