  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
