This avoids hardcoding any implementation-specific limitiations as
part of the API, and allows for future expandability.
This also allows API users to more conveniently convert the
values into floats without hardcoding specific conversion constants.
The API was committed a few days ago, so changing this field now
is within the realms of acceptable.
ffprobe is meant to generate parseable output, and if a field is present, it
should be printed even if it has a default value.

Add external encoder VVenC for H266/VVC encoding.
Register new encoder libvvenc.
Add libvvenc to wrap the vvenc interface.
libvvenc implements encoder option: preset,qp,qpa,period,
passlogfile,stats,vvenc-params,level,tier.
Enable encoder by adding --enable-libvvenc in configure step.

The code only set the channel layout of the AVFormatContext, so the user could
not override the channel layout if the demuxer did not have such parameter.
This used to work via the respective AVCodecContext option, but since
639c2f0049 it no longer gets passed to the
decoders. It is actually better if we set it manually, instead of using the
codec option because that way we can also override it on the stream level, so
it will also work for stream copy or bitstream filtering.
We don't allow changing the number of channels, because that can cause
unexpected results. We disable layout guessing, if a channel layout is
specified.
Fixes ticket #11016.

Do this by attaching the FilterGraph directly to more permanent
storage from which it will be automatically freed.

Both the codecpar's width and height, and the SAR num and den are
ints, which can overflow. Cast to int64_t, which is what av_reduce
takes.
Without this, occasionally, display_aspect_ratio can be negative in
ffprobe's -show_stream output.

This allows one complex filtergraph's output to be sent as input to
another one, which is useful in certain situations (one is described in
the docs).
Chaining filtergraphs was already effectively possible by using a
wrapped_avframe encoder connected to a loopback decoder, but it is ugly,
non-obvious and inefficient.
The decision whether -apad actually does anything is made based on muxer
properties, and so more properly belongs there. Filtering code only
receives the result.
Instead pass the encoder through a newly-added output options struct,
analogous to previously added input options.
Will allow decoupling filtering from encoding in future commits.
