SQL support for phandle verifier, etc. Changes to use phandle verifier from foundation to distinguish processes when pids are recycled. Remove some workarounds which attempted to use process creation timestamps to do the same thing. Also, use msg_mon_node_down2 to log the reason why the node is brought down. And removed some unneeded special case code to free the shared segment semaphore at the startup of mxssmp.
Enable basic Runtime Management System (RMS) The goal of these initial changes is to get the shared memory segment created, build and start the persistent server processes mxssmp and mxsscp, make EXE processes register in the shared segment and let mxssmp cleanup the shared segment as the processes stop. Later I will address specific features of RMS that support Query Invalidation.
