This commit does for AVInputFormat what commit
59c9dc82f4 did for AVOutputFormat:
It adds a new type FFInputFormat, moves all the internals
of AVInputFormat to it and adds a now reduced AVInputFormat
as first member.
This does not affect/improve extensibility of both public
or private fields for demuxers (it is still a mess due to lavd).
This is possible since 50f34172e0
(which removed the last usage of an internal field of AVInputFormat
in fftools).
(Hint: tools/probetest.c accesses the internals of FFInputFormat
as well, but given that it is a testing tool this is not considered
a problem.)

Do not propagate the return value of avformat_write_header(),
as it contains the information whether the output had
already been initialized in avformat_init_output(),
but this is set generically; the return value of
FFOutputFormat.write_header is not documented at all
(and is currently ignored if >= 0), but it is more future-proof
to simply return 0 on success.

This is intended to avoid -Wformat= warnings on systems
where %s might not be supported (and also generally emitted
by GCC with -pedantic).

It is undefined behaviour to use a different type for a call
than the actual type of the function.

This separates the URL-layer adjacent parts of the code
from the parts that are also usable with custom IO.

Some encoders, like flac, propagate updated extradata at the end of encoding
as packet side data. Use it to update the relevant codec_config.

Rebased on top of recently merged fixes (should apply correctly now).
In merged DVD patch, -pgc and -pg options were broken. While these are
rather advanced options, they are the only means to get content for
some strangely authored discs.

The mpegts code historically tries to strip (the first) metadata access unit
header from synchronous KLV metadata, but the detection for such streams was
unreliable causing strips of asynchronous metadata or ID3 as well.
MISB ST 1402 specifies required stream type, stream id and registration
descriptor (which eventually maps to the codec ID) so let's use all of these
for reliable detection.
Fixes a regression caused by 468615f204.
Fixes ticket #10828, #10883.

The inner AVInputFormat* of the inner mpegps-demuxer
is only used once (in avformat_open_input()), so
don't even store it. In fact, just use ff_mpegps_demuxer
directly, as this demuxer has a configure dependency
on it.

The wav demuxer by default tried to demux 4096-byte packets which caused
packets with very few number of samples for files with high channel count.
This caused a significant overhead especially since the latest ffmpeg.c
threading changes.
So let's use a similar approach for selecting audio frame size which is already
used in the PCM demuxer, which is to read 25 times per second but at most 1024
samples.

We typically are only interesed in a single type of metadata set, so it is
better to keep them separated instead of always filtering for them.
Also use av_dynarray_add for increasing their array.

UUIDs do not have to be unique if their type sets them apart, so avoid using
AnyType, since we are only interested in specific types.

It is undefined behaviour.
Fixes many failed tests with UBSan and GCC 13 like
"src/libavformat/mov.c:4229:44: runtime error: store to address
0x5572abe20f80 with insufficient space for an object of type 'struct
MOVIndexRange'"

is assigned.)
