Cleanup and fix bugs in the MPI dynamics section. Modify the dpm API so it properly takes ports instead of process names (as correctly identified by Aurelien). Fix race conditions in the use of ompi-server. Fix incompatibilities between the mpi bindings and the dpm implemenation that could cause segfaults due to uninitialized memory.

Fix the ompi-server -h cmd line option so it actually tells you something!

Add two new testing codes to the orte/test/mpi area: accept and connect.
