Merge remote-tracking branch 'qatar/master'

Browse Source 
* qatar/master:
  configure: add support for bdver1 and bdver2 CPU types.
  avio: make avio_close NULL the freed buffer
  pixdesc: cosmetics
  proresenc: Don't free a buffer not owned by the codec
  proresenc: Write the full value in one put_bits call
  adpcmenc: Calculate the IMA_QT predictor without overflow
  x86: Add convenience macros to check for CPU extensions and flags
  x86: h264dsp: drop some unnecessary ifdefs around prototype declarations
  mss12: merge decode_pixel() and decode_top_left_pixel()
  mss12: reduce SliceContext size from 1067 to 164 KB
  mss12: move SliceContexts out of the common context into the codec contexts
