Respect the returned AVFrame from avcodec_decode_video

Description

Currently, we only respect tempFrame in DecodeBand? for VP3, and for some reason enabling it for other codecs doesn't work right. This will be necessary in the future, when we enable more decoders and I merge frame-multithreading, so we should try to always use them. To avoid buffer copies, we should still override (re)get_/release_buffer and implement retain counting so that frames are still around until DrawBand?.

I still don't understand how this stuff all works, but several other codecs (ffmpeg-mt anything, FFV1) just crash when they're used. Will investigate some tricks with reordered_opaque.
