1. Added pid_t to the dps
2. Processes now "register" their local pid and update their location (i.e., nodename) on the registry during mpi_init
3. Added a new error code for values that exceed maximum for their data type (useful when transitioning a value from one variable to another of different size)
4. Fixed a few places where size_t was being incorrectly handled
5. Updated dps_test to cover pid_t types
This should now provide support for TotalView connection - which David is pursuing.
