This merge adds Checkpoint/Restart support to Open MPI. The initial
frameworks and components support a LAM/MPI-like implementation.
This commit follows the risk assessment presented to the Open MPI core
development group on Feb. 22, 2007.
This commit closes trac:158
More details to follow.

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

be used in MPI_Alloc_mem operations. Note that we found an interesting bug in
which if memory was allocated by the sm mpool (via mmap) and then registered
via the mvapi mpool, the registration would fail on certain systems.
Added mca param mpool_base_use_mem_hooks, set to 1 to enable the memory hooks
so that memory is deregistered if the user frees it behind our back. This is
only useful if the mca param mpi_leave_pinned is also set to 1. Otherwise all
registrations are deregistered within the MPI library or via
MPI_Free_buf. After testing we should probably set both mpi_leave_pinned and
mpool_base_use_mem_hooks to default to 1.

- move mpool and allocator frameworks back to ompi (from opal)
- specialize the ompi_free_list class to use an mpool instance
- un-specialize opal_free_list to *not* use mpool; just use malloc/free
