6c583e9048 avcodec/opusdec: Fix delayed sample value
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.

1ae092587f avcodec/opusdec: Clear out pointers per packet
This is safer than to assume that all error pathes cleared them and
nothing will use uncleared pointers.

ffa05e0802 avcodec/opusdec: switch to swresample
This also fixes linking failures in doc/examples which where apparently
caused by the linking order between avcodec and avresample

  lavc: add a native Opus decoder.

Conflicts:
	Changelog
	configure
	libavcodec/version.h

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)
