Michael Niedermayer c3c2db49a7 Merge remote-tracking branch 'qatar/master' 
* qatar/master:
  cook: expand dither_tab[], and make sure indexes into it don't overflow.
  xxan: reindent xan_unpack_luma().
  xxan: protect against chroma LUT overreads.
  xxan: convert to bytestream2 API.
  xxan: don't read before start of buffer in av_memcpy_backptr().
  vp8: convert mbedge loopfilter x86 assembly to use named arguments.
  vp8: convert inner loopfilter x86 assembly to use named arguments.

Conflicts:
	libavcodec/xxan.c
