* qatar/master:
  mpegvideo_enc: use the AVFrame API properly.
  ffv1: use the AVFrame API properly.
  jpegls: use the AVFrame API properly.
  huffyuv: use the AVFrame API properly.

Conflicts:
	libavcodec/ffv1.c
	libavcodec/ffv1.h
	libavcodec/ffv1dec.c
	libavcodec/ffv1enc.c

Changes to ffv1 are more redone than merged due to them being based on
an ancient codebase and a good part of that having being done already
as well.
