* Removed unneeded zlib dependency
 * Renamed zlib to zstd in tests to reflect the change of the pub_sub library to use zstd.

Added a zlib:// transport which is placed as a filter before the pub/recv. ex:  zlib://tcp://127.0.0.1:9000.

 * Removed the mx_stream/dx_stream directories.
 * Removed cmake detection for mx/omx.
 * Removed some checks for older C++ atomics.

 * restructure code so the main logic is in a library.
 * add basic build setup for go
 * renamed the executable as go does not like non test things to end in _test.go

 * simple process management when a test needs multiple processes
 * temp directory management (and cleanup)
 * scriptable
 * less verbose than bash

 * Updated cps_xmit/recv, cds_pub_sub, local_dc to work with posix shmem or mbuf
 * Add tests that use posix shmem for daqd, cps_recv/xmit, cds_pub_sub, local_dc

Try to keep things to one build of the code, most/all of this can be done at run time.

 * Remove the GPSCLOCK cmake config option
 * Revert edcu.c and sdf_monitor.c.  These are not used anymore and should just be dropped (for another commit).
 * Removed dead symmetricom/gps code from standalone_edcu.cc.
 * Updated the gps logic used by standalone_edcu.cc (gps.hh) to use gpsclock instead of the system time if /dev/gpstime is not available.
 * Minor refactor of the controllerAppUser.c and controllerIopUser.c to reduce the number of ifdefs (for ease of reading)
 * Reworked local_dc.c to use gpsclock to use /dev/gpstime if available or gpsclock if it is not available.

This code can be used when models run in userspace and without GPS hardware.
It removes the dependency on the special device file /dev/gpstime.
GPS time is obtained in userspace from the system clock.
Enable at compile time by defining USE_GPSCLOCK.
When building a model, add userspacegps=1 to the CDS parameters.

This was done to allow the use of pyepics instead of caget to check for epics status.

Also removes the bash based test.

Cds_pub_sub now understands input from rmipc:// (FE mbuf inputs) and output to daqm:// (daqd memory buffers, daq_multi_cycle_t in a mbuf).

* The socket has been renamed from pipe to daqd_socket
* Defaults to a working dir of /var/run/nds
 * socket path is then /var/run/nds/daqd_socket
 * jobs dir is then /var/run/nds/jobs
* Set the --socketdir option on nds to specify the working dir

This is being done to help with some systemd unit files.

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.

Ran clang format.

Use transport-independent RPC package (tirpc) if available,
otherwise use RPC headers if still available.
Mostly for non-Debian compiles, as Debian asserts non-default
flag in glibc to retain the old RPC support

This allows disconnected channel lists to be extracted from the edc.

Local_dc reads RT model data from mbuf (rmIpcStr) concentrates the data
into one block and stores it in an output mbuf (daq_multi_cycle_data_t).

In a standalone system this would be the data concentrator.  On a larger
system, this prepares data for a streamer process.

This also adds a basic test for local_dc which starts several local
simulated FE streams, concentrates their data and checks that each
channel is available in the output with the expected values.

This removes fe_data_concentrator.
This updates code in fe_stream_test.
This adds a new fe_stream_check, renaming the old (and disabled) one
to fe_stream_check_nds.

This also enables cmake based testing.

!!Warning the tests fail unless mbuf and gpstime are enabled!!

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.

Added cmake detection for dolphin.  Currently the cmake is hardcoded for
an IX adapter and the sisci library.

Added ix_fb_rcv and zmq_rcv_ix_xmit as cmake built targets.

Updated the ix_stream/zmq_stream makefiles to use the zmq_transport files.

Minor changes to make sure that zmq_fe/zmq_thread/zmq_rcv_ix_xmit/ix_fb_rcv
populate headers and lay out data in the same way.

Added test code to ix_fb_rcv to read data from an mbuf instead of dolphin
to allow debugging on a non-dolphin system. -B sets the source mbuf name.

Allowed added the -b flag to zmq_rcv_ix_xmit/ix_fb_rcv to allow overriding
the mbuf that is used.

Found that ix_fb_rcv was always copying the 1st buffer/stride/cycle from the
daq_multi_cycle_data_t structure in the dolphin, fixed it to push out the
cycle it was claiming to copy over.

With flex <= 2.5 yyin/yyout are pointers, with 2.6+ they are member
objects of the generated lexer.  Adapt the build system to detect which
is in use, and the code to work with both variants in flex.

Among other items allows daqd to build on both Debian 8 & 9.

This is to give us integration with modern tooling, out of tree builds, and easier packaging.

This is not yet ready for production.
