Josh Hursey d2ef0d445a Add some basic timing hooks so I can extract a few more detailed performance

numbers for tuning.

Switch the bookmark_recv to be non-blocking. If this is blocking then for
process counts >= 32 slight process delays were causing cascading performance
delays in the protocol. This lead to checkpoints either taking about 3 sec or
45 sec (or more) for 64 procs due to the cascading delays. With the nonblocking
receive version this is no longer the case we get the speedup we expect for this
part of the protocol.

More tuning to come.

This commit was SVN r16137.

attribute

Make it so the universe size is passed through the ODLS instead of through a gpr trigger during MPI init. This matches what is currently being done with the app number.
