  westwood_vqa: fix SND0 chunk handling
  westwood_vqa: set video stream duration
  raw: forward avpicture_fill() error code in raw_decode().
  build: Do not explicitly add the doc directory to the OBJDIRS list.
  dv: Split off DV video decoder into its own file.
  build: fix RALF decoder standalone compilation, which depends on Golomb code
  configure: Drop stray duplicate entry for --disable-fft from help output.

Conflicts:
	libavcodec/dv.c
	libavcodec/rawdec.c
