startup sequencer: when START_MODELS is false, run startup sequencer, but don't link start_world.target to multi-user.target.  All the unit files should be created, but models, edc, local_dc and cps_xmit won't start.

GDSTP screen "IO" time modified to show most of ADC read time in microseconds.

Closes #280

awgtpman: stream and awg buffers now allocated based on model rate.

awgtpman: stream and awg buffers now allocated based on model rate.  This keeps memory usage low on slow systems, while allocating big enough buffers for fast systems.

fix x2sqz build failure related to goto->goto change

Closes #268

See merge request cds/advligorts!256

Some models have dangling "From" tags that are not linked to anything.  RCG now issues a warning and just deletes the tag.

RCG: add_line() used by remote_tags() in Parster3.pm now creates different 'Branch' and 'Line' objects as required by find_branch().  This change fixes remove_busses(), which was operating on the second segment of complex lines, but neede the first.

"TOTAL" time now reads this same IO time plus the time to run through all 'UNDERSAMPLE' or 'clock_div' model calculations.

For most models that amounts to only one calculation, but for a fast ADC model running at 524 Hz, but spitting out data at 65 Hz, that's all 8 calculations.

Fix RCG so that Goto -> From pairs can lead directly into another Goto.

synchronization frequency output from -b option made to pull from correct register.

rcg: Changed add_line so that it will work if the parent line, perhaps erroneously, has children (they won't get deleted).  "remove_destination" sets empty string instead of "undef" to destination label.

Add several diagnostics registers to the LPTC driver and to the related /sys file system

See merge request cds/advligorts!252

gpstime: lptc_info script now handles all "on board" registers including temperature, voltages and currents.

internal power supply registers /sysfs output changed to look like a comma separated array, same as the external supply.

Corresponding packaging changes are needed.

Fix dolphin_timer_xmit to update cycles at the right rate: 2^16 Hz

See merge request cds/advligorts!254

Fix dolphin_timer_xmit to send cycleNum/clock_div.  This brings PCI timing back down to 65k for fast iop xmiters.

rcg: Fix made for rcg failure when a goto -> from pair leads directly into another goto.  The RCG was creating multiple output lines for the same node, which is generally ok but breaks an assumption made in the Goto-From removal code.  See gitlab #268 for full explanation.

lptc_info.py prints useful diagnostics information about the first LIGO PCIe Timing Card that it finds attached to the PCIe bus.
It decodes various registers produced by the card and expressed in /sys/kernel/gpstime/lptc, including slot-specific registers.

gpstime module must be installed to use.  If an LPTC is not attached, then gpstime will not create the /sys/kernel/gpstime/lptc directory nor its contents.

LPTC driver and gpstime: Many more diagnostics register functions added for the LPTC driver.  These values are also brought out into the /sys file system in /sus/kernel/gpstime/lptc when gpstime is running.

Some functions added to lptc driver to expose diagnostics registers.

lptc specific diagnostics and slot-specific registers brought out in /sys/kernel/gpstime/lptc

some functions that belong to ligoPcieTiming_core.c were moved there from ligoPcieTiming.c

Added LIGO PCIe timing card to gpstime.  Some changes made to the ligo timing...
