Fixes an issue in 6.1 when reading a corrupted file with -xerror would
exit with success. This specific issue is not present in master, but
this should generally be a more robust behaviour.

Do not pass an options dictionary to the avcodec_open2() in enc_open().
This is cleaner and more robust, as previously various bits of code
would try to interpret the contents of the options dictionary, with
varying degrees of correctness. Now they can just access the encoder
AVCodecContext directly.
Cf. 372c78dd42 - analogous change for
decoding.
A non-progressive field order is now written on the container level in
interlaced ProRes encoding tests.
Share the code between encoding and decoding. Instead of checking every
stream's options dictionary (which is also used for other purposes),
track all used options in a dedicated dictionary.
Not sure this change makes sense, the code is more robust with ret set

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.

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.
