API BEHAVIOR CHANGE: FLAG_FORCE_MASKED is now deprecated (or better:
obsolete) since this has now become the default behavior. New flag
FLAG_FORCE_UNMASKED gets you back to the old default of unmasking and
trimming the whole DUT before starting the test. THIS REQUIRES FW
2.19 TO WORK CORRECTLY!
Do not "reset" the PG in daqStop() since there is nothing to reset to.
