This is based on jpeg2000 but differs because of
problems with the design from jpeg2000 with currently
supported files

More files can be decoded after this commit, though they
show heavy artifacts

Adding an arbitrary amount of padding bytes at the end of the
ID3 metadata fixes cover art display for some software (iTunes,
Traktor, Serato, Torq).

For reference (ID3 metadata):

[ Apic frames ]                      -> cover doesn't show up
[ Apic frames, Padding ]             -> ok
[ Apic frames, ID3 frames ]          -> ok
[ ID3 frames, Apic frames ]          -> cover doesn't show up
[ ID3 frames, Apic frames, Padding ] -> ok

Checking seek table crc in decoder is pointless, as seek table is not used in
decoder anyway, so also stop storing seek table into extradata.

Fixes Ticket2606

This function is never called with values large enough for the
error condition to occur

This fixes a TODO item and unifies both decoders structures
It also fixes undefined behavior due to aliasing violations

I choose 2 fields instead of a union because mistakely using the
wrong type with a union will lead to hard to debug "wrong output"
while with 2 fields mistakely using the wrong type will crash
with a null pointer derefernce which is much easier to debug

2 of the changes are replaced by assert0s, as they should
be impossible.
The actual bug is likely caused by a invalid block_align
which is checked for and thus impossible in ffmpeg.
