Michael Niedermayer a7acab6cda Merge remote-tracking branch 'qatar/master'
* qatar/master:
  vc1dec: Remove separate scaling function for interlaced field MVs
  vc1dec: Invoke edge_emulation regardless of MV precision
  x86: Use consistent 3dnowext function and macro name suffixes
  g723_1: scale output as supposed for the case with postfilter disabled
  g723_1: increase excitation storage by 4
  g723_1: fix upper bound parameter from inverse maximum autocorrelation
  g723_1: make scale_vector() behave like the reference
  g723_1: fix off-by-one error in normalize_bits()
  g723_1: save/restore excitation with offset to store LPC history
  wmapro: prevent division by zero when sample rate is unspecified
  x86: proresdsp: improve SIGNEXTEND macro comments
  x86: h264dsp: K&R formatting cosmetics
  LICENSE: Document all GPL files

Conflicts:
	libavcodec/g723_1.c
	libavcodec/wmaprodec.c
	libavcodec/x86/h264dsp_mmx.c
