#7967: ID3v2 comment unsupported

Summary of the bug: id3v2enc.c does not encode "comment" metadata using
ID3v2 tag "COMM", it instead drops though and gets encoded using the
"TXXX" catch-all. The metadata mapping table in id3v2.c needs to be
updated with the "COMM" tag for the "comment" key; and
id3v2_check_write_tag in id3v2enc.c should not expect valid tags to start
with "T" since "COMM" is an obvious exception to that constraint.
How to reproduce:
{{{
% ffmpeg-i mp3_with_COMM_id3v2_tag.mp3 -f ffmetadata -c copy -map_metadata
0 -id3v2_version 3 -write_id3v1 1
incorrect_mp3_with_comment_mapped_to_TXXX_tag.mp3
ffmpeg version
built on ...
}}}
Patches should be submitted to the ffmpeg-devel mailing list and not this
bug tracker.
