[Vorbis] "aoTuV" beta5.5 released

[Aoyumi]

This is the library of Ogg Vorbis I conformity.
  I performed original tuning (part of encoding) for the reference
source code of Ogg Vorbis of Xiph.Org to origin.

***** Changed part from beta5 *****
   # The noise control of the Impulse block was expanded. This is
effective with the outstanding sample of the pre-echo.
   # The pre-echo reduction code came to work at a lower bit rate.
   # Noise Normalization was reviewed. As a result, the bug is revised.
   # The detailed tuning was done again.
