4264e4056c lavc/hevc_ps: fix variable signedness in ff_hevc_decode_short_term_rps() 
It is actually supposed to go negative in the loop over num_negative
pics, but underflow does not break anything as the result is then
assigned to a signed int.

6fed1841a1 lavc/hevc_ps/HEVCSPS: change flags into uint8_t 
Reduces sizeof(HEVCSPS) by 64 bytes.

Also improve flag names: drop redundant suffixes and prefixes, and
consistently use disabled/enabled.

bd1a06dc43 lavc/hevc_ps: reduce the size of used_by_curr_pic_lt_sps_flag 
It is currently an array of 32 uint8_t, each storing a single flag. A
single uint32_t is sufficient.

25ce44efa5 lavc/hevcdec: track local context count separately from WPP thread count 
The latter can be lowered while decoding, which would lead to memleaks.

a1471ec8ad lavc/hevcdec: rename HEVCContext.HEVClcList to local_ctx

c309285666 avcodec/vc2enc: Avoid relocations for short strings 
These strings are so short that they can be put directly

Also use chars for interlaced and level while at it, as
these are so small.

02ecf8d7f3 avcodec/vc2enc: Fix slice length 
args->bytes here already includes prefix_bytes (see
SSIZE_ROUND macro), so including it here again and
forgetting it when offsetting skip seems wrong.
This only works because prefix_bytes is currently
always zero in this encoder.

add8c46215 Revert "avformat/file: seek back to initial position for fd protocol" 
The generally expected behaviour is for software to append from the
current position, not to keep resetting. See also how shell works:
 # (foo && bar) > file
...would normally concatenate the output of both commands to file.

If foo seeks like lavf, bar would instead overwrite the output of
foo (possibly not completely).

This reverts commit 5c3d2177e7be7dde69a83b1b394f57976c164c84.
