be1e6e7503 Merge remote-tracking branch 'qatar/master' 
* 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.

abe76b851c ffv1enc: Make ffv1.3 non experimental 
The fate tests change as they used 1.2 previously
The increased size is due to:
32bit CRCs per slice by default (can be disabled),
it adds slice headers to allow decoding one slice without the others
an additional slice size field is added to make it possible to find
slices within corrupted surroundings.

these add up to about 57bit per slice more
at 50 frames and 4 slices thats 1425 byte
