Cleanup ompi/dpm operations
Do some code cleanup in the connect/accept code. Ensure that the OMPI
layer has access to the PMIx identifier for the process. Add macros for
converting PMIx names to/from strings. Cleanup a few of the simple test
programs. Add a little more info to a btl/tcp error message.
