Merge remote-tracking branch 'qatar/master'

* qatar/master:
  x86: dsputil: prettyprint gcc inline asm
  x86: K&R prettyprinting cosmetics for dsputil_mmx.c
  x86: conditionally compile H.264 QPEL optimizations
  dsputil_mmx: Surround QPEL macros by "do { } while (0);" blocks.
  Ignore generated files below doc/.
  dpcm: convert to bytestream2.
  interplayvideo: convert to bytestream2.
  movenc: Merge if statements
  h264: fix memleak in error path.
  pthread: Immediately release all frames in ff_thread_flush()
  h264: Add check for invalid chroma_format_idc
  utvideo: port header reading to bytestream2.
