Merge remote-tracking branch 'qatar/master'

* qatar/master:
  h264: K&R formatting cosmetics
  s3tc.h: Add missing #include to fix standalone header compilation.
  FATE: add capability for audio encode/decode tests with fuzzy psnr comparison
  FATE: allow a tolerance in the size comparison in do_tiny_psnr()
  FATE: use absolute difference from a target value in do_tiny_psnr()
  FATE: allow tests to set CMP_SHIFT to pass to tiny_psnr
  FATE: use $fuzz directly in do_tiny_psnr() instead of passing it around
