RV bring-up: RVT "system time" heartbeat messages now get printed every 20 s! The problem was a slight Nucleus API incompatibility between what the RVF code from TCS211 expected and what our FreeNucleus implements: in the TCS211 version of Nucleus it was OK to pass 0 for the initial_time parameter to NU_Create_Timer(), but our version flags such usage as an error. RVF used 0 as the dummy initial_time value when initializing the legacy RV timers with NU_DISABLE_TIMER. Implemented fix: using a dummy value of 1 instead.
