18AI32 ADC module. Need to go back at some point and add proper
1PPS sync code for this module.

Bug Fix: Chnage to main.c checkFileCrc to not use /usr/bin/chkSum to avoid code hangup

See merge request cds/advligorts!137

if bootserver locks up.
- Changed the checkFileCrc routine to do perform file checksum, consistent with other
  CDS code.
- Added a file modification time check.
Sequence now :
   - check file mod time
   - If mod time changed, then read file and compute CRC
   - If CRC changed, then report modified file
   - If CRC did not change, file not modified so reset modtime

release

Minor updates to the daq_wiper script

See merge request cds/advligorts!129

Update local_dc to better support running a standalone edc.

Closes #136

See merge request cds/advligorts!135

 * Fixed a logic error that kept the rate from being looked up when it was not specified
 * Updated the dcu/rate extraction logic to work with a full model name
 * Added a model name trimming function to remove the optional dcuid/rate from the name, to help make the intent of some code cleaner in local_dc.c
 * Updated tests

Standalone edc's don't need a par file.  We use par files to get dcuid's and model rates.  This update expands local_dc to allow specifying a dcuid & rate on the command line.

Added some unit testing code to local_dc
Updated the standalone edc test to use inline dcuid notation
Converted local_dc to use the arg library

Cleanups and fixes for the standalone_edc

Closes #135

See merge request cds/advligorts!134

 * Allow _C- for raw/commissioning frames
 * Remove an '+' that was left in when converting from string concatenation to path joins.

 * Convert to using os.path instead of manual path creation
 * Estimate the number of TB of data per day and use that as a default amount of free space to hold to.

 * fix the systemd unit to use the corect argument for the listen interface 'l' instead of 'I'
 * convert the standalone_edc to use the args library, and update the documentation
 * add a '_daq' to the end of the edc's mbuf name, so that it is similar to the models
   * Note this is transparent to the user, the '_daq' should not be added on (either to the name passed into the edc or to local_dc)
 * Updated the edc test to not specify '_daq' anywhere.

Added 20bit DAC timing diags for test

Closes #133, Fix for a stack smash in standalone_edc.

The boost spsc queue has a suprising api.  Change the pop call to give a specific maximum to the number of items popped.

of controllerIop.c to adc_info.c.

- Addition of FE_STAT MEDM screen with items formally in /proc files.
- Fix to channel hopping error message.

Correct the path of the sphinx generated pdf file.

Minor tweaks to the sphinx gitlabci setup to make it work

See merge request cds/advligorts!132

sphinx documentation skeleton

Have the cmake install process install a frame wiper and daq ini file archiver.

See merge request cds/advligorts!131

Request that services start after remote-fs.target is reached.

These are utility scripts used when running the daqd.

checkdaqconfig - freezes the config, archiving it by time & contents
daq_wiper - this deletes old frames to keep disks from filling on a frame writer

Done for:
 * daqd
 * nds
 * local_dc
 * edc

This is the python3 script used at LHO for frame wipping.  Moving it from userapps to the advligorts repository.

This script is responsible for running every hour and freeing up space on the disk system for new frames.

Sphinx is a documentation generator using reStructuredText:

https://www.sphinx-doc.org/en/master/index.html
https://www.sphinx-doc.org/en/master/usage/restructuredtext/index.html

This builds out the initial skeleton of the documentation.  Changes
can be tested by running make in the documentation tree:

 $ cd doc2
 $ make html

The generated pages are available at

 doc2/_build/html/index.html

This also include gitlab CI to build the documentation at publish it
at the gitlab documentation pages:

- Added daq_prefix option for Parameter block.  This allows proper
  creation of GDSTP screen DAQ info for systems that do not connect
  to the standard DAQ-DC0.

- Fix for 1PPS sync.

- Removed GeFanuc RFM code from controllerIOP.c as no longer supported.
- Update to ADC startup when using external clock w/o 1PPS sync.
