score follower input.

identifier for each incoming MIDI message. This is then used as the 'muid'
arg. to cmScMatcherExec() to support definitively matching score events and
particular MIDI events.

fed to cmScMatcher are now tracked along with the note.  This allows score events
to be definitevly matched to a particular note-on event when the event
comes from a MIDI file.

their own type: kPedalEvtScId and pedal down messages are assigned the
pedal event duration in cmScEvent_t.durSecs.

reflect the meaning of the score markers.

the length of time the pedal is held down and the 'pitch' field is set
to the MIDI id of the pedal.

sustain pedal messages with the length of time the sustain pedal is held down.

Added kNoteNoSpid and kFailSpId messages to the score tracking processor callback.

score processing algorithms without changing the processor.
Created the shell code for generating performance editing data.

Comment out calls to cmFrqTrk.

Changed fieldWidth and decPlCnt from unsigned to int in PrintF()
Added #ifdef OS_OSX conditional compile around ilaenv_() in LUInverse().

Removed dead code _cmDspSys_TlXformChain1().

1) Added two new audio inputs (ai2p,ai3p) and mixers (mx0p,mx1p)
to allow contact mic's to be mixed with air mic's.
2) Added two new audio outputs (a02p,a03p) which are duplicates of
   ao0p and ao1p.
3) Added all pass filters to all four audio outputs to decorrelate output.
4) Added Bypass button to bypass the all pass filters.

Commented out cmFrqTrkPrint() in cmSpecDistInit().

On failure of cmThreadMutexWaitOnCondVar() in _cmRtThreadCallback() the
correct result code is now reported.
