  x86: Don't declare a non-static function as inline
  
  This fixes building with clang in msvc mode, which does support
  gcc style inline assembly.

• amfenc : Retain a reference to D3D frames used as input during the encoding process

  amfenc: Retain a reference to D3D frames used as input during the encoding process
  
  This fixes frame corruption issue when decoder started reusing frames
  while they are still in use of encoding process
  
  Issue with frame corruption  was reproduced using:
  
      avconv.exe -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i input.h264 -an -c:v h264_amf output.mkv
  
  It is recommended to use -extra_hw_frames 16 option in case if hw frames
  number in pool is not enough

• lavc/qsvdec : set complete_frame flags for progressive picture

  lavc/qsvdec: set complete_frame flags for progressive picture
  
  Set the flag MFX_BITSTREAM_COMPLETE_FRAME when it is a progressive picture.
  This can fix vc1 decoding segment fault issues because can't set the start
  code correctly.
  
  See: ./avconv -hwaccel qsv -c:v vc1_qsv -i /fate-suite/vc1/SA00040.vc1
  -vf "hwdownload, format=nv12" -f rawvideo /dev/null
  
  v2: fix some h264 interlaced clips regression
  a. field_order of some h264 interlaced video (e.g: cama3_vtc_b.avc) is marked as AV_FIELD_UNKNOWN
     in h264_parser.c. This is not a completed frames.
     So only set the MFX_BITSTREAM_COMPLETE_FRAME when it is progressive.
  b. some clips have both progressive and interlaced frames (e.g.CAPAMA3_Sand_F.264),
     the parsed field_order maybe changed druing the decoding progress.
  
  This patch has been verified for other codecs(mpeg2/hevc/vp8).

  libaom: remove references to RGB pixfmts
  
  Support for it was apparently never in the codebase, and the enum
  values were recently removed from the public headers [1]
  
  Fixes build with latest libaom build.
