Merge remote-tracking branch 'qatar/master'

* qatar/master:
  avcodec: remove AVCodecContext.dsp_mask
  avconv: fix a segfault when default encoder for a format doesn't exist.
  utvideo: general cosmetics
  aac: Handle HE-AACv2 when sniffing a channel order.
  movenc: Support high sample rates in isomedia formats by setting the sample rate field in stsd to 0.
  xxan: Remove write-only variable in xan_decode_frame_type0().
  ivi_common: Initialize a variable at declaration in ff_ivi_decode_blocks().

Conflicts:
	ffmpeg.c
	libavcodec/utvideo.c
