38bcb3ba7b avformat/iamf_parse: fix parsing AAC DecoderConfigDescriptor
Use ff_mp4_read_descr() to read both the tags and the vlc value
that comes after it, which was not being taken into account.

93281630a7 lavc/vvc: Validate explicit subpic locations

position and size of subpictures whose dimensions are provided
explicitly.

01701bdcd5 lavc/vvc: Prevent OOB access in subpic_tiles
The previous logic relied on the subpicture boundaries coinciding with
the tile boundaries.  Per 6.3.1 of H.266 (V3), vertical subpicture
boundaries are always tile boundaries however the same cannot be said
for horizontal subpicture boundaries.  Furthermore, it is possible to
construct an illegal bitstream where vertical subpicture boundaries are
not coincident with tile boundaries.  In these cases, the condition of
the while loop would never be satisfied resulting in an OOB read on
col_bd/row_bd.

Patch fixes this issue by replacing != with <, thereby not requiring
subpicture boundaries and tile boundaries to be coincident.

removing some people who have not been active where others where active

For most we will need to contact people and ask if they are still available as maintainers
(but for cases where patches are ignored for many months even with pings sent to the maintainer
 entries should be set to unmaintained)
