This is the daqd memory format, daq_multi_cycle_data_t in daq_core.h.

The zmq streamers where kept around as a off the shelf method to move data for small (test) systems.  However the pub/sub code appears to work better, and has no distribution limitations either.  So remove the zmq code in favor of the pub/sub.

Previously the simple_pv library had provided a pipe to serialize framed json data to as a way to export debug information.  Then an external process dc_cas.py would read from the pipe and reflect the data into EPICS.  This is a reworking of the code to remove the external process and provide an interface to export int and string values into EPICS.

* Removes dc_cas.py
* Removes the old simple_pv.c
* Adds in a simple abstraction around an EPICS pCas server (C and C++ interfaces provided)

This brings in:
* Updates to the cmake build to support FrameCPP 2.6+
* Various startup scripts for Debian8 & Gentoo 3.0
* Daqd files updated to match branch 3.5
* Moved over the ix/zmq/mx stream work from 3.5
* The split of daq_core.h into daq_core.h & daq_core_defs.h to
centralize declarations.

It is now README-cmake.txt.

Fixed some errors and added sample instructions for installing cmake from source.
