awgtpman: deletion of unneeded #if directives in awgtpman.  Those deleted here seem to be trivially unneeded.  There are many more that require some research.

In addition to cleaning up #if 0 and #if 1 directives, the following symbol assumptions were made:

OS_VXWORKS undefined
TARGET = 0
RMEM_LAYOUT = 2
GS_UNIX_TARGET defined
PORTMAP = 1
OS_SOLARIS undefined
_LINUX defined
_CONFIG_DYNAMIC undefined
__GNUC__ defined
linux defined
P__DARWIN undefined
__CYGWIN__ undefined
RTLINUX undefined
__linux__ defined
P__SOLARIS undefined
HAVE_CONFG undefined
SITE undefined

Simplified awg data mbuf handles excitation data streaming from awg to models

See merge request cds/advligorts!215

awgptan: build working with explicit sized integers.  mbuf analyze improved to show the first working awg slot.

rcg, awgtpman: simplified awg data mbuf works for streaming to IOP.  user models build but aren't tested.

awg data used to be in the mbuf named <model_name> along with test points, epics data and a DAQ info structure.

data is now passed through <model_name>_awg.  The entire mbuf is mapped with the AWG_DATA structure.

There's no longer any need to calculate offsets.  Access code is much simpler.  Expansion or reconfiguring of the mbuf layout will be straightforward.

Awgtpman GDS reconciliation, new build

contains the rate at which the IOP is sending data to user application
models. This was added to support awgtpman when IOP is passing data at
other than normal 65536 samples/sec.

awgtpman: removed relative paths from some target_include_directory() calls.  Added some missing headerfiles that should have been in the last commit

GDS/AWGTPMAN: missing header files included in src/gds/awgtpman/dtt.  Also gmutex files added to src/gds/base.  These are used by NDS and are separate from awgtpman. Now builds in a pristine container with only mk-build-deps isntalled.

Awgtpman reconciled with GDS replaces previous awgptman.  Build changed to DTT style awg build.  The main difference is that rpc files are built out of tree.

A GDS linkage to daqd has been removed.  This will need to be addressed in a future commit.

checkdaqconfig: filling another hole in the master file parsing.

checkdaqconfig: filling another whole in the master file parsing that would cause an exception.  Also, updated the test file to work with the latest version of pytest.

Daqd update, serve data from circular buffers before going to disk if possible.

Consolidated the online and in memory logic in the net_writer into one location, making sure the absolute gps request gets a termination block.

Updated the nds live test to also test doing a in buffer test with absolute gps times.

Previously requests that did not have a start/delta time could go from the buffer by default, and a start/delta would read from frame first and then finish up in reading from ram.
The implications are that short reads that use absolute gps times that fall in the time span the data is available but where a frame has not been written yet will fail as it will attempt
to read a frame, fail, then return.  This pushes a check up front to see if the start/delta is caught completely in the in memory buffer and then attempts to read that before falling back to reading from frames.

 * Changes needed to make passed in parameters const char* instead of char*.
   * This included cleaning up a number of other functions that should have been able to work with const char*
 * extracted some network address and parsing functions from the daqd and net_writer class into standalone functions.
   * This was done to allow unit testing as it otherwise pulled in all of daqd.
 * In the start * writer code, replaced the gotos with returns as we are now in a standalone function.
