It has been deprecated in 94d68a41fa
and can't be set via AVOptions. The only codecs that use it
(the MPEG-1/2 encoders) have private options for this.
So remove it.

This commit does for AVOutputFormat what commit
20f9727018 did for AVCodec:
It adds a new type FFOutputFormat, moves all the internals
of AVOutputFormat to it and adds a now reduced AVOutputFormat
as first member.
This does not affect/improve extensibility of both public
or private fields for muxers (it is still a mess due to lavd).

It is the most commonly used field and moving it to the start
e.g. allows to encode the offset in a pointer+offset addressing
mode on one byte on x86.

Analogous to -enc_stats*, but happens right before muxing. Useful
because bitstream filters and the sync queue can modify packets after
encoding and before muxing. Also has access to the muxing timebase.
Since at least 4.4.3, -ab/-b:a help text was in the video section
of ffmpeg -h, but these are audio options.

Current HLS implementation simply skip a failed segment to catch up
the stream, but this is not optimal for some use cases like livestream
recording.
Add an option to retry a failed segment to ensure the output file is
a complete stream.

We parse the fallback cHRM on decode and correctly determine that we
have BT.709 primaries, but unknown TRC. This causes us to write cICP
where we shouldn't. Primaries without transfer can be handled entirely
by cHRM, so we should only write cICP if we actually know the transfer
function.
Additionally, we should avoid writing cICP if there's an ICC profile
because the spec says decoders must prioritize cICP over the ICC
profile.

We need to construct the output format list separatedly from the input
format list, because we need to adhere to two extra requirements:
1. Big-endian output formats are always unsupported (runtime error)
2. Combining 'vulkan' with an explicit out_format that is not supported
by the vulkan frame allocation code is illegal and will crash (abort)
As a free side benefit, this rewrite fixes a possible memory leak in the
`fail` path that was present in the old code.

Since many distributions ship libjxl 0.7.0 still, we'd still prefer to
compile against that, but don't want to lose the features that require
libjxl 0.8.0 or greater. For this reason I've added preprocessor #ifdef
guards around the features that aren't necessarily in libjxl 0.7.0.

Splits the currently handled subtitle at random access point
packets that can be configured to follow a specific output stream.
Currently only subtitle streams which are directly mapped into the
same output in which the heartbeat stream resides are affected.
This way the subtitle - which is known to be shown at this time
can be split and passed to muxer before its full duration is
yet known. This is also a drawback, as this essentially outputs
multiple subtitles from a single input subtitle that continues
over multiple random access points. Thus this feature should not
be utilized in cases where subtitle output latency does not matter.

This way we can call process_subtitles without causing the decoded
frame counter to get bumped.
Additionally, this now takes into mention all of the decoded
subtitle frames without fix_sub_duration latency/buffering, or filtering
out decoded reset/end subtitles without any rendered rectangles, which
matches the original intent in 4754345027
.

QSVDeintContext and VPPContext have the same base context, and all
features in deinterlace_qsv are implemented in vpp_qsv filter, so
deinterlace_qsv can be taken as a special case of vpp_qsv filter, and we
may use VPPContext with a different option array, preinit callback and
support pixel formats to implement deinterlace_qsv, then remove
QSVDeintContext.
