Vorbis Encoders

Vorbis-OptSort: This patch improves source code of the Vorbis codec library(libvorbis-1.0) to accelerate encoding time about 10% (not apply clean on 1.1.1). Consider applying it in the next version of libvorbis ;)
AoTuV beta4 encoder: Optimized encoder for higher quality. Note that this patch also include the Vorbis-OptSort patch. Quality test of AoTuV beta4 vs. libvorbis 1.1.1:
- 80Kbps comparison of many audio codec and libvorbis 1.1.1 with AoTuV beta4
  - summary
- 96Kbps summary
Optimized Ogg Vorbis Encoders: these are highly optimized encoders developed by the Ogg Vorbis Acceleration Project that are much faster than the standard builds with negligible to no effects on audio quality.
