Due to a somewhat high volume of complains, phase inversion has
been made optional with RFC8251. This allows for better bass
frequency response when partially downmixing to play on systems
with an LFE speaker.

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.

Make ff_opus_parse_extradata free allocated memory on error instead of
expecting callers to free it in that case.

The intention is to have both encoding and decoding functions

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.

Fixes out of array access
Fixes: ffmpeg_opus_crash1.ogg
This solution is likely not optimal in terms of error concealment but
its simple and fixes the out of array access.

This is safer than to assume that all error pathes cleared them and

Fate tests pass with both avresample as well as swresample based opus decoder, but

if theres an alternative or if they could be avoided, they also dont match the
