Merge remote-tracking branch 'qatar/master'

* qatar/master:
  swscale: convert yuv2yuvX() to using named arguments.
  swscale: rename "dstw" to "w" to prevent name collisions.
  swscale: use named registers in yuv2yuv1_plane() place.
  lavf: fix aspect ratio mismatch message.
  avconv: set AVFormatContext.duration from '-t'
  cljr: implement encode2.
  cljr: set the properties of the coded_frame, not input frame.
  dnxhdenc: switch to encode2.
  bmpenc: switch to encode2().

Conflicts:
	libavcodec/bmpenc.c
	libavcodec/cljr.c
	libavformat/utils.c
	tests/ref/vsynth1/cljr
	tests/ref/vsynth2/cljr
