* Don't need the 2 process case -- we'll send an extra message, but
at very little cost and less code is better.
* Use COMPLETE sends instead of STANDARD sends so that the connection
is fully established before we move on to the next connection. The
previous code was still causing minor connection flooding for huge
numbers of processes.
* mpi_preconnect_all now connects both OOB and MPI layers. There's
also mpi_preconnect_mpi and mpi_preconnect_oob should you want to
be more specific.
* Since we're only using the MCA parameters once at the beginning
of time, no need for global constants. Just do the quick param
lookup right before the parameter is needed. Save some of that
global variable space for the next guy.
