Fixes a reported (but false) race condition in tsan for fate-apng:
WARNING: ThreadSanitizer: data race (pid=6274)
Read of size 4 at 0x7d680001ec78 by main thread (mutexes: write M1338):
#0 update_thread_context src/libavcodec/pngdec.c:1456 (ffmpeg+0x000000dacf0c)

Previous write of size 4 at 0x7d680001ec78 by thread T1 (mutexes: write M1335):
#0 decode_idat_chunk src/libavcodec/pngdec.c:737 (ffmpeg+0x000000dae951)
Values from subsequent values are guaranteed to be identical (since
poc and nal_unit_type are checked to be the same between slices), so
this doesn't affect output in any way, but does resolve the remaining
reported race conditions (by tsan) in fate-hevc.
In practice, this fixes tsan warnings like this:
WARNING: ThreadSanitizer: data race (pid=25334)
Read of size 4 at 0x7d9c0001adcc by main thread (mutexes: write M1386):

#0 hls_slice_header src/libavcodec/hevcdec.c:596 (ffmpeg+0x000000b43a22)
Otherwise the thread may still be in the middle of decoding a previous
frame, which would effectively trigger a race condition on any field
concurrently read and written.
In practice, this fixes tsan warnings like the following:
WARNING: ThreadSanitizer: data race (pid=17380)

Should fix tsan warnings in fate-fifo-muxer-h264/wav:

Fixes tsan warnings in several audio codecs (flac, alac, wavpack, tta
and tak) that look like this:
WARNING: ThreadSanitizer: data race (pid=14340)
Read of size 4 at 0x7d64000169d8 by main thread (mutexes: write M1335):
#0 update_context_from_thread src/libavcodec/pthread_frame.c:284 (ffmpeg+0x000000dc795f)

#0 wavpack_decode_block src/libavcodec/wavpack.c:1012 (ffmpeg+0x00000112b175)
This is how the ref list manager links bitstream IDs to H264Picture/Ref
objects, and is local to the producer thread. There is no need for the
consumer thread to know the bitstream IDs of its references in their
respective producer threads.
In practice, this fixes tsan warnings when running fate-h264:
WARNING: ThreadSanitizer: data race (pid=19295)
Read of size 4 at 0x7dbc0000e614 by main thread (mutexes: write M1914):

#0 build_def_list src/libavcodec/h264_refs.c:91 (ffmpeg+0x0000013b46cf)
This avoids an integer overflow
the solution matches oggparsevorbis.c and 45581ed15d
