* New/improved bootstrapping technique for DLLs
* First cut of the MPI handle debugging interface. It is still
evolving, but the interface is getting more stable.
* Some minor bugs were fixed in the unity topo component (brought to
light because of the new MPI handle debugging stuff).
Fixes trac:1209.

* 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.

r10877:
add warm up connection option.. of course this only warms up the first
eager btl but this should be adequate for now..
r10881:
Consulted with Galen and did a few things:
- Fix the algorithm to actually make the connections that we want
- Rename the MCA param to mpi_preconnect_all
- Cleanup the code a bit:
- move the logic to a separate .c file
- check return codes properly

API is still a bit unstable and may change.
- Add a primitive "first use" component that simply has each process
"touch" the pages that they want to use, thereby [hopefully] locking
them locally to a specific processor
- Add hooks in ompi_mpi_init to enable memory affinity when processor
affinity is used.
- Added hooks in ompi_mpi_finalize to shut down memory affinity when
it was initialized during ompi_mpi_init.
- Added right hooks in ompi_info to display maffinity components.
