For now require edc ini entries to be floats @ 16Hz.

fe_stream_check_edcu_nds.
Given a timespan (w/o gaps) it checks:

 * That there is a consistent number of (*)EDCU_CHAN_(CONN|CNT|NOCON)
values.
  * There can be no non-connected channels for this test
 * It then samples a number of channels that were generated by a
 synthetic generator and verifies they have the expected values.
  * To deal with delays in epics changes being propagated, the comparison
 looks at the current second and the previous second and allows a blending
 of their values.

This is used to give a prefix to the connected/not-connected/... variables.

Introducing a new edu application.

This is a regular application, based on the edcu iocsh application, but
without being an epics iocsh.  This is oriented towards a quick deployment
of an epics->frame archiver w/o setting up an edc model.

As we only store 32bit floats in daq data stream, only deal with floats.
Then remove double->float cast in the fast copy loop.
Update the fast copy loop to be a memcpy.

simple_pv was written to support zmq, but is used by other streams and
does not require zmq.  This change moves it to its own area and makes
sure it is always built, even when zmq is not found.

Also removed an unneeded header from dix_xmit.c.  Its presence was
noticed when the includes changed for the simple_pv move.

This should allow the system to build when open-mx is present.

Tests:
 * daqd
 * nds

fe_multi_stream_test can now write out individual models mbufs (the
rmIpcStr structure) as well as a combined daq_multi_cycle_t structure.

Remove fe_stream_test, rework the zmq/local_dc tests to use
fe_multi_stream.

The channel mix wasn't properly generating mid data rate range channels.

The test is to:

* start a simulated IFO (via fe_multi_stream_test)
* start daqd
* read live data from nds
* verify the data

This updates the NDS2 client detection, reimplements fe_stream_check_nds,
and adds some test harness logic.

Adding a proposed clang-format style to the repository, along with a helper script.  This is for evaulation.

To use, "reformat_files *.c *.h".  It just makes sure that the -i and -style="file" get added to the clang-format call.

fe_stream_test is a single front end outputing a rmIpcStr to mbuf.

fe_multi_stream_test can be used to simulate fe systems in bulk, it
outputs to a dac_multi_cycle_t in mbuf, along with populating a
ini directory and master file.  This is targeted for daqd development
and testing.

This adds a fe_generator_support library which holds some common code
between the two generators.

This also adds another check to fe_stream_check, verifying the data crc.

Fix usage message in local_dc.

Remove commented out code in the makefile and associated .c code

Looking for variables with ix_ prefix and removed an usused bit.

* Renamed the cmake target ix_xmit to dix_xmit.  Copied in code from mx2ix.c, removed the
mx specific bits.
* Reformatted local_dc.c, explicitly checking for 64bit alignment in tests
* fe_stream_check requires that the dataCycleSize is 8 byte aligned.
* Adding a simple test program to the ix_stream area.

ix_test -g <num> -s - sending/server side test
ix_test -g <num> -c - recieving/client side test
ix_test -g <num> [-c] -d - recieving side, dump first 64 bytes of data

* dix_xmit waits for the input buffer to be valid before checking buffers.

If you read the input mbuf before it is ready you will likely have invalid
input and will make bad assumptions about buffer lengths and data strides.

So wait until data is ready and then start up.

* Moved ix_fb_rcv.c to dix_recv.c.  Ran clang-format on the code.  Reviewed
the program arguments.

Primary change is to load TP/EXC via for loop instead of memcpy, as memcpy caused kernel panics with Debian 10 and gcc 8.3.
Also, I beutified the code using clang-format, which accounts for the multitude of diffs.
