Milestone #9608: Down Converter Test
ACNET devices for plotting DDC buffers
ACNET devices that we can use to plot the DDC buffers at the end of the 0x20 cycle.

Verified that we can program a raw measurement and readout with the state machine then read it out with the ACNET raw data devices.
Had to fight a bit with the ees-buildroot environment in order to build bpmacsys on adlinuxdev for the first time.
Will now move on to implementing the DDC readout devices using the raw readout devices as a template.

Receiving bad offset/length errors when attempting to read more than 100 points from Z:HIABOO test device (TBT I data).
Forgot about the cdev configuration file (bbpmts.conf) that also includes a maximum length (was set to 101).
Set the TBT ACNET devices to the maximum length: 32764 (not sure why, but I can't use 32768).

Interpreting the offset as a page number won't work with Synoptic array plots. The Array widget will divide the request for 8000+ samples into four requests of 2048 or less. This assumes that the offset is a real array index and ultimately leads to a seg fault.
E-mailed Linden asking if we could change this behavior. Will find out from Charlie when his "big array" support in ACNET will be finished...
