Josh Hursey 88aa45dd52 Commit to bring online OpenIB, MX, and shared memory support for Open MPI's checkpoint/restart functionality. Some tuning is still needed, but basic functionality is in place.
There is still a problem with OpenIB and threads (external to C/R functionality). It has been reported in Ticket #1539

Additionally:
* Fix a file cleanup bug in CRS Base.
* Fix a possible deadlock in the TCP ft_event function
* Add a mca_base_param_deregister() function to MCA base
* Add whole process checkpoint timers
* Add support for BTL: OpenIB, MX,  Shared Memory
* Add support Mpool: rdma, sm
* Sundry bounds checking an cleanup in some scattered functions

This commit was SVN r19756.
