Comment 30 for bug 383240

I started pulling r19955 and r19956, but r19956 has a bunch of changes to the AAC decoder which don't apply probably because I need more aac.c changes. aac.c saw a bunch more commits in the recent history, it's a very active file. I don't think it's reasonable to try to backport its changes.

Then there's the problem that the changes touch dsputil.h which API is used all over the place. I'm not too happy to change it as it might impact other decoders or even other applications, but almost all interesting changes touch it.

So I dropped revs after 19957 except r20151 and am trying another build.
