07b78340dd opus_celt: rename structures to better names and reorganize them
This is meant to be applied on top of my previous patch which
split PVQ into celt_pvq.c and made opus_celt.h

Essentially nothing has been changed other than renaming CeltFrame
to CeltBlock (CeltFrame had absolutely nothing at all to do with
a frame) and CeltContext to CeltFrame.
3 variables have been put in CeltFrame as they make more sense
there rather than being passed around as arguments.
The coefficients have been moved to the CeltBlock structure
(why the hell were they in CeltContext and not in CeltFrame??).

Now the encoder would be able to use the exact context the decoder
uses (plus a couple of extra fields in there).

FATE passes, no slowdowns, etc.

7d3baebe40 opus_parser: fix leaking channel_maps on error
Make ff_opus_parse_extradata free allocated memory on error instead of
expecting callers to free it in that case.

14e5580246 opusdec: properly handle mismatching configurations in multichannel streams
The substreams can have different resampling delays, so an additional
level of buffering is needed to synchronize them.

Fate tests pass with both avresample as well as swresample based opus decoder, but
are disabled (reference files are very large so i want to think a day or 2 about
if theres an alternative or if they could be avoided, they also dont match the
official samples)
