It is only used by demuxers (and it is generally demuxers
who have to translate format-specific IDs to stream indices).

They are also needed by the MMSH and MMST protocols and therefore
the file they are in is pulled in when these protocols are enabled
and used. By moving them to a separate file, linking statically to
libavformat while only using AVIO no longer pulls in all the
muxers/demuxers (and also no longer any AVCodecs when linking
statically to libavcodec).

It is not forbidden to call this with a muxer, so it is moved to
avformat.c and not demux_utils.c. ff_find_decoder(), which is used
by av_find_best_stream() is also moved as well, despite being even
more geared towards demuxers.

While it is clearly written with demuxers in mind,
it is not forbidden to call it with muxers, hence avformat.c
and not demux_utils.c.

It is not explicitly forbidden to call these functions with muxers
(although it is probably intended to be only called by demuxers;
av_guess_sample_aspect_ratio even says that "the stream aspect ratio
is set by the demuxer").

It is not to call this with a muxer, so move it to avformat.c

This file will contain the AVFormatContext-specific parts
that are used by both demuxers and muxers.

It is only used by demuxers (although it is hypothetically
possible that some day e.g. a protocol might need it, but
that is unlikely given that they don't deal with AVCodecParameters).

It is demuxer-only: It potentially adds an AVStream and it sets
AVStream.attached_pic.

This function is only intended for demuxers (as calling it doesn't
have any observable effect for a muxer).

It is demuxer-only: Muxers deal only with chapters given to them;
they don't create any of their own.

This file is both for the various public APIs that are demuxer-only
as well as for the demuxer-only internal functions.

ff_get_packet_palette() and ff_reshuffle_raw_rgb() belong together:
E.g. the former takes the return value of the latter as argument.
So move ff_get_packet_palette() to rawutils.c (which consists solely
of ff_reshuffle_raw_rgb()).
Also add a separate header for these two functions.

It is only used by muxers. Given that it is not part of
the core muxing code and given that mux.c is already big enough,
it is moved to a new file for utility functions for muxing.

This is the appropriate place given that AVStream is about to
become an AVOpt-enabled struct.
Also move av_disposition_(to|from)_string, as these are tied
to the disposition stream option.

Also improve the size check a bit; given that av_realloc_array()
checks for overflow itself, we only have to check for
nb_side_data + 1 still being representable in an int.
But given that we can check for representability in size_t
at no additional cost we do so as it leads to a nicer error code.

This avoids having to rebuild big files every time FFMPEG_VERSION

This way values such as maxrate/bufsize can be utilized further
down the chain.
First, syncs up the max_rate and buffer_size from SVT-AV1 back to
avctx, and then in case at least one of the utilized values is
nonzero, adds the CPB properties side data.
This way we can filter out the default value for this member, which
is nonzero. Bases on the current affairs that bit rate based rate
control is nonzero in SVT-AV1.
filter-pp and filter-pp7 are the only ones of the filter-pp* tests
that use the file generated by fate-vsynth1-mpeg4-qprd.
Also combine the dependency on this test for all the tests that need it.
