Merge remote-tracking branch 'qatar/master'

* qatar/master:
  audio_frame_queue: Clean up ff_af_queue_log_state debug function
  dwt: Remove unused code.
  cavs: convert cavsdata.h to a .c file
  cavs: Move inline functions only used in one file out of the header
  cavs: Move data tables used in only one place to that file
  fate: Add a single symbol Ut Video decoder test
  vf_hqdn3d: x86 asm
  vf_hqdn3d: support 16bit colordepth
  avconv: prefer user-forced input framerate when choosing output framerate

Conflicts:
	ffmpeg.c
	libavcodec/audio_frame_queue.c
	libavcodec/dwt.c
