  swscale: split out x86/swscale_template.c from swscale.c.
  swscale: enable hScale_altivec_real.
  swscale: split out ppc _template.c files from main swscale.c.
  swscale: remove indirections in ppc/swscale_template.c.
  swscale: split out unscaled altivec YUV converters in their own file.
  mpegvideoenc: fix multislice fate tests with threading disabled.
  mpegts: Wrap #ifdef DEBUG and av_hex_dump_log() combination in a macro.
  build: Simplify texi2html invocation through the --output option.
  Mark some variables with av_unused
  Replace avcodec_get_pix_fmt_name() by av_get_pix_fmt_name().
  svq3: Check negative mb_type to fix potential crash.
  svq3: Move svq3-specific fields to their own context.
  rawdec: initialize return value to 0.
  Remove unused get_psnr() prototype
