de1b44c206 avformat/matroskaenc: handle AV1 extradata in packet side data

223d2bde22 Improve hls VOD mode hls performance problem. 
This fixes the creation of the hls manifest in hlsenc.c by writing the
entire manifest at the end for VOD playlists. Live & Event Playlists are unaffected.
This also fixes the behavior with HLS_TEMP_FILE to work correctly when
-hlsflags temp_file is specified, instead of always relying on use_rename, which caused these problems.

Files that would previously take over a week to fragment now take
1 minute on the same hardware. This was a 153 hour audio file (2.2GB of audio).

728760de35 Revert "avcodec/libaomdec: auto insert dump_extra bitstream filter" 
This reverts commit e45ed15594.

The Matroska spec was updated to not remove Sequence Header OBUs from key
frames, so this is no longer needed.

8d5604a69a avformat/av1: update ff_isom_write_av1c() to the latest revision of the spec 
This will get ISOBMFF and Matroska up to date with the revised AV1 Codec
Configuration Box spec.
For now keep propagating raw OBUs as extradata until all libavcodec modules
are adapted to handle AV1CodecConfigurationRecord formatted extradata.
