Added cmFrqTrk to cmSpecDist and did initial real-time testing.

Initial addition of cmFrqTrk to cmSpecDist. (not yet tested).

read 'procSmpCnt' blocks until the end-of-file is reached.

the same name as an existing node attempts to synchronize.

instead of #ifdef OS_64.

to use cmRtNetSyncMsg_t.hdrByteCnt.

Changed cmRtNetMsg_t.endptId to dstEndPtId.

cmRtNetEndpointIsValid(),cmRtNetEndPointId(),cmRtNetEndPointLabel().

Added srcEndPtId to all 'sending' functions.

_cmRtNetRecv() now sets cmRtNetMsg_t.srcNodeIdx.

rather than at cmRtNetEndPointRegister().

cmNetAlloc().  rtSubIdx is no longer required to locate a remote endpoint
because IP/"node label" is enough information to determine the rtSubIdx.
Several changes were made to simplify the interface to cmRtNet based on this
observation.

Added comments.

Removed the use of useBuiltInFl from _cmDspSysPgm_Stereo_Through().
