Make gds broadcasts work

See merge request cds/advligorts!119

Historically, there have been two main types of broadcasts in daqd, the DC data stream (the 10Gb udp broadcast) and the GDS frame transfer.  When DATA_CONCENTRATOR was defined only the DC data stream is used.  This mode has been removed from the daq architecture.  So the only remaining broadcast mode should be the GDS frame transfer.

The big difference between the two broadcast methods is the data source.  For the DC stream the source is the main circular buffer.  For the GDS the data source is a frame file that the framer_io function mmaps and pushes as a block of memory.

There were several modes of operation for the daqd, and DATA_CONCENTRATOR was picked when collapsing the daqd down to one binary.  So remove support for the DC data stream.
 * Removes support for broadcasting testpoints
 * Removes the udp broadcast logic for the DC stream
 * Removes a number of #if DATA_CONCENTOR macro guards
 * Removes a number of #if GDS_TESTPOINT macro guards

 The final flow of the broadcast data is now as follows:

 the parser sees the request for the net-writer with a broadcast address.
 This triggers a net writer to be created, a producer thread to start, a circular buffer to be created.  The producer copies data from the main circular buffer and unlocks the main circular buffer it puts into the new circular buffer with a nowait put operation (which is allowed to fail).  Nothing has ever emptied this, so a consumer thread is not launched (it didn't do anything anyways).

From the user perspective, key changes are in the model Parameter block settings:
- An IOP model should now be designaeted with iop_model=1
	- Previously set by adcMaster=1
- A user control application should have the adcSlave=1 parameter removed.
	- If iop_model=1 is not in the Parameter block, then RCG assumes
	  this is a user control application model.
- IOP models that send/rcv timing over the Dolphin network
	- The transmitter model Parameter block needs dolphin_time_xmit=1
	- A recevier IOP model Parameter block needs dolphin_time_rcvr=1

Partial cleanup of the code to change the verbage and names in comments and code.

Work to remove slave from the code.  This is not a complete cleanup, but it goes through

 * src/daqd
 * src/gds
 * src/gdsConfig
 * src/mx_stream

Code to allow models to continue running up to 61msec in event of
a Dolphin network hangup.  Required additional IOP Parameter
setting to be invoked.

Change an || to an &&, so the loop that waits for work or a stop signal exits when one of those conditions is met.

hangups for up to 61msec.

Make awg prefer TARGET environment variable and clean up behavior WRT param paths and model rates.

awgtpman now prefers to use the TARGET environment variable for the target directory.
If not present, /opt/rtcds/<site>/<ifo> will be used.
If neither TARGET nor SITE and IFO are set, awgtpman will refuse to load
and print a helpful error.

awgtpman will look in $TARGET/target/gds/param for the parameter files
to get the model rate.
awgtpman will now fail with a helpful error when the model rate cannot be found.
If the '-r' option is set, then awgtpman will uses exclusively the command line arguments to
determine model rate and won't check the param files.
awgtpman will ignore command line arguments for setting the model rate unless '-r' is given.

Prevent install from updating testpoint.par with epics-only models.

tests if kernel module was created before updating testpoint.par.  This prevents epics only models from ending up in testpoint.par.

Daqd not exiting issue 96

See merge request cds/advligorts!115

 * Spelling fix, changing to stop_function_t from stop_funtion_t.
 * Corrected the timed circular buffer get to timeout.

Move all the trender threads to being tracked by a thread handler and having a uniform stop signal.

Add a timed_get function to the circular buffer which will allow queries to the circualr buffers to time out.  This is used to allow the trender to see a stop request.

Converting it to use atomics.

This is done as part of expanding the wrapping of the pthread... calls with C++.  Starting on a interface to better track threads.

Awgtpman purge site map

See merge request cds/advligorts!114

Merge branch 'awgtpman-purge-site-map' of ssh://git.ligo.org/erik.vonreis/advligorts into awgtpman-purge-site-map

Added back in site_prefix and archive.  Removed awgapi.h and awgapi.c for being unused.  cleaned up readChnInfo() in gdschannel.c, but it now no longer tries to open a non-existant channel database file.

support: update wrapper scripts to check SITE/IFO and export TARGET vars

See merge request cds/advligorts!112

updates awgtpman command line args, checks SITE/IFO exist, and exports
TARGET env var.

Fix for #120.  Removes the unused '-d' command line options.

Closes #120

See merge request cds/advligorts!111

Also removes some other unused variables.
