      Most checked-in files had a comment with a filename and
      last-modified string automatically updated by the
      subversion version control tool. These became obsolete
      when we migrated the repository to git. Remove them.

      Commit a first cut of 5.1 tuning. · 8ca7e056

      One last thing to try, aside from a longer training run, would be to use pairwise L/R 
      codebooks on uncoupled data in higher q modes, where the 'stereo abuse' strategy worked well, 
      probably due more to codebooks backend than the stereo coupling pairs.

      reel back low midrange noise bias ever so slightly.  This eliminates
      the 'cupping' noise in the low midrange that's somewhat more noticable
      than other blocking noise.

      Lower absolute ATH to no more than -130dB, -140 nominal.  Carsten has
      found enough conterexamples at this point to disprove the rationale
      for a lowest-possible ATH in masking; the only value it has left is to
      give a bottom end to the dB range to avoid FP underflows.

      Elimintae two minor bugs; zero-bark wraparound in noise_hybridmp was
      slightly off, and <0 fixed evelope computation should be allowed to
      dip below zero (and be bounded later).

      Turn off HF dipole stereo.  The elliptical stereo from rc3, despite
      slightly more centered hiss, simply works better.

      Lots more preecho tuning after detailed feedback from Juha (JohnV).  I
      think I pass all his test cases now.  General behavior is much
      tighter, less hacked, even yet a bit faster.

      Continued preecho tuning/fixes.  Gone to average dB with even/odd
      smoothing, and cranked the sensitivity back up to ala rc3.  Result:
      when rc3 and current are working 'properly', current trips _slightly_
      more impulse blocks but also catches many more audible cases.  Current
      also seems more resistent to false positives.

      New preecho detection/short block trigger code, replacing an IIR
      subbander filterbank with a fourier based subbander.  The primary
      intent is lower memory usage and greater speed, but this technique
      should also provide slightly superior results.
