Recording has been tested but reading the recorded files has not. Initial commit.

These timestamps are set in _cmRtDspExecCallback() by cmApBufGetIO().
_cmRtSysEnable() now calls cmApBufOnPortEnable() to allow cmApBuf to be
aware of the audio stream starting and stopping.

the cmApBufGetIO() calls in _cmAsDspExecCallback().
_cmAudioSysEnable() now calls cmApBufOnPortEnable() to that cmApBuf() can
be aware to when audio streaming is starting and stopping.

cmApBufUpdate() sets an input/output timestamp on each device according to the audio packet timestamp.
cmApBufGetIO() returns the timestamp associated with each returned buffer.
Added cmApBufOnPortEnable() to zero the timestamp when a port is enabled.
This implementation of the audio timestamping processes is a hack because
only the first timestamp is stored (after a call to cmApBufOnPortEnable())
and all subsequent timestamps are generated by incrementing this value according
to the incoming/outgoing sample count.

This was required to address a strict-aliasing violation in the release build.

The original function is in _cmDspSysPgm_TimeLine2().

computation in _cmMpMIDISystemReadProc().

(dyn,even,tempo,cost) as they are computed.

no available channels are available.

which can be used with specific on/off values and symbols.

Changed container values from integers to flags so they can be mixed with
basic data types when used with var-arg based functions.
Added cmErr_t* arg's to all var-arg based functions.

to support window size on the Goertzel detector.

in _cmDspGoertzelReset.

from the system frame rate (procSmpCnt) to cmGoertzel.

Added comments.
Fixed bug in filling record buffer.

spat lab mac.

overwrote 'rc' and thereby prevented the functio from returning the correct result code on fail.
