Added support for MV-HEVC encoding for stereoscopic videos (2 views
only). Compatible with the framepack filter when using the
AV_STEREO3D_FRAMESEQUENCE format.

Previously, AV1 used filler data with CBR by default while H.264
and HEVC may or may not depending on driver version. Make this
consistent by using not filler data in CBR mode for all codecs.
Since there are valid reasons to use CBR with or without filler,
also add a cbr_padding option to allow users to override this.

These properties are unreliable because they depend on the frames decoded so
far, users should check directly the presence of the decoded AVFrame side data
or AVFrame flags.

libjxl supports animated encoding, so we add a wrapper to the
library using the receive_packet callback method.
This code was based largely on a patch sent by Zsolt Vadász,
although it was updated to use more recent coding practices
and many of the leaks and issues were fixed.

The current parser does things which a parser should not, like skipping parts
of the packet header, but it does not actually able to packetize a raw DNXUC
bitstream.
Rework the parser logic to work similar to other parsers and be able to
correctly packetize raw DNXUC bitstreams.
Bump minor version because the DNXUC codec packet format changes with this.
Normally this would be a breaking change, but in this particular case it should
not cause any issues in practice because the DNXUC codec is relatively new and
we never added a decoder for it.

xHE-AAC is a profile where some frames depend on other key frames, named IPF.
By setting the codec as Intra Only, all frames output by decoders and all
packets output by encoders/demuxers will be unconditionally flaged as
keyframes, which is incorrect.
Should fix ticket #11272.

For example, with
./ffmpeg -operating_rate 400 -hwaccel mediacodec -i test.mp4 -an \
-c:v h264_mediacodec -operating_rate 400 -b:v 5M -f null -
The transcoding speed is 254 FPS.
Without -operating_rate on dec/enc, the speed is 148 FPS.
With -operating_rate on decoder only, the speed is 239 FPS.

Use AV1DecContext's current_obu to access the original OBUs, and
feed them to videotoolbox, rather than the bare slice data passed
via decode_slice.
This requires a small addition to AV1DecContext, for keeping track
of the current range of OBUs that belong to the current frame.

This replaces the myriad of existing lists in AVCodec by a unified API
call, allowing us to (ultimately) trim down the sizeof(AVCodec) quite
substantially, while also making this more trivially extensible.
In addition to the already covered lists, add two new entries for color
space and color range, mirroring the newly added negotiable fields in
libavfilter.
Once the deprecation period passes for the existing public fields, the
rough plan is to move the commonly used fields (such as
pix_fmt/sample_fmt) into FFCodec, possibly as a union of audio and video
configuration types, and then implement the rarely used fields with
custom callbacks.
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.
