I tried in f631c328e6. Long story short, it was a disaster, since
AVCodecContext.extradata is supposedly owned by the caller in decoding
scenarios, and some projects started crashing because of it. Had to be
reverted in 87588caf8c. So any solution will have to be internal but
less ugly, or an API change.
