and standard ADC at 64kHz within the same I/O chassis.

getmodelrates() refactored and awgtpman can learn model rate from files.

See merge request cds/advligorts!92

patched in Jonathan's test and case refactoring.  Renamed getmodelrate() to get_model_rate_dcuid() Created some tests for get_model_rate_dcuid().  Fixed Bug where slower models always had multiplier set to one.  awgtpman now sets multiplier based on 2kHz if model is slow. Improved includes a bit.

add /etc/advligorts/systemd_env to rts-awgtpman@.service.  Awgtpman now needs IFO and SITE variables to find model rate.

awgtpman calls getmodelrate(), which has been changed to fix two issues: the previous implementation could change the case of environment variables and crashed if either the IFO or SITE environment variables were undefined.

refactored getmodulerate() into /util/modelrate.c.  Affects local_dc, mx_stream, pub_sub_stream.  I was unable to build mx_stream due to missing openmx.  local_dc builds but is not tested.  pub_sub_stream builds and pasts ctest, but it also passed when getmodelrate() was an empty function.

Update a comment to correct a name.  Put a magic number into a constant.

1) For now, the RCG will accept either ifo= or site=, eg ifo=X2 or site=X2 to designate the IFO in the cdsParameter block. This
    obviates the need for immediate changes to present Matlab control models. All new models, and eventually all old models,
    should use the ifo= designator as the site= designator will be deprecated in a TBD future release.
2) At compile time, if a model still contains the site= designator, a warning message will be written to alert user to change to ifo=.
     This is simply a warning for now.
3) I have gone thru all the RCG Perl code to change site to ifo, where appropriate.  I think things are consistent now ie site is a
     location eg lho, llo, lao, etc. and ifo is the IFO designator eg ifo=H1, L1, A1, etc.

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

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).

Created cds_pub_sub from cps_recv
Added a sub plugin for the rmIpcStr based mbufs from the FE systems.

- Added check in ADC initialization code.
- Passed back as a new ADC status bit (3)
- Added status bit to GDS_TP screen ADC status
- Since difficult to remember what bits mean, ADC status bit info
  added with labels to the auto generated MONITOR_ADC screens.
- Note that this bit is only reported by IOP models.

provides a listing of available Parameter block settings.

IOP: setting virtualiop=1 will force all IPCs defined in the model to
	become SHMEM type regardless of model definintion.
USER APP: setting use_shm_ipc=1 will force all IPCs defined in the model to
        become SHMEM type regardless of model definintion.

Parameter block options.

Close Issue #87 - delete setup sub-folder, already moved to new cds/rts-admin project

Fix a typo in installing mbuf_probe, put it in bin not BIN

See merge request cds/advligorts!85

   - Deprecated old, non-functional on Debian 10, controllerVirtual.c.
   - Parameter block entry "virtualIOP=1" sets the appropriate compile flags.
   - controllerIOP.c modified with addition of RUN_WO_IO_MODULES option
   - Added timing control in time_slave_io.c
Further changes are still required to feed data into the ADC inputs.  As is,
ADC inputs are statically set to value of channel number eg channel 31= 31.

Closes #98.  Check for dcuids that are not normal and abort.
