  Give all anonymously typedeffed structs in headers a name
  fate: Add parseutils test
  parseutils-test: Drop random colors from parsing test
  vf_pad/scale: use double precision for aspect ratios.
  build: error on variable-length arrays
  ppc: swscale: rework yuv2planeX_altivec()
  ppc: fmtconvert: kill VLA in float_to_int16_interleave_altivec()
  x86: dsputil: kill VLA in gmc_mmx()
  libspeexenc: Updated commentary to reflect recent changes
  libspeexenc: Add an option for enabling DTX
  doc/APIchanges: fill in missing dates and hashes.
  lavr: bump major to 1 and declare it stable.
  lavr: change the type of the data buffers to uint8_t**.
  lavc: deprecate the audio resampling API.
