This reverts commit e45ed15594.

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

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.

Also only initialize it in ff_av1_packet_split() and not ff_av1_extract_obu(),
same as h2645_parse, so GetBitContext specific failures may not affect the
latter.

Neutrals are supposed to be anything not black (0,0,0) and not white
(N,N,N).

Previous neutral filtering code was too strict by excluding colors with
any of its RGB component maxed instead of just the white color.
