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.

Ticket 158 --> https://svn.open-mpi.org/trac/ompi/ticket/158
* use one-sided datatype check instead of send/receive and check both
the origin and target datatypes
* allow error handler to be set on MPI_WIN_NULL, per standard
* Allow recursive calls into the pt2pt osc component's progress
function
* Fix an uninitialized variable problem in the unlock header
This commit was SVN r12667.
* Print a warning error message if a target is not in an exposure epoch
and an update is received. This results in the app continuing with
that call having never happened, rather than evil hangs.

full argument checking (allowing that MPI_PROC_NULL is legal, of course).
Only after the argument checking do we shortcut. Fixes trac:237, which
was caused by moving the MPI_PROC_NULL test in MPI_Bsend_init,
but not allowing for MPI_PROC_NULL when checking rank.

you can't be in a post and a start at the same time, and that is clearly
legal to do
* Fix interptretation of when the epochs start for MPI_Fence. Only start
an epoch if communication actually occurs, otherwise it isn't actually
an epoch. I don't know who thought that wording in the MPI standard
was a good idea, but can't change it now...

- 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)
This commit was SVN r8985.
* Implement fortran handle -> c handle tracking
* Remove some unneeded locking around free lists (the free list
macros do their own locking)
* Try to be a bit more memory friendly with the w_mode setting /
checking

complete, but stable enough that it will have no impact on general development,
so into the trunk it goes. Changes in this commit include:
- Remove the --with option for disabling MPI-2 onesided support. It
complicated code, and has no real reason for existing
- add a framework osc (OneSided Communication) for encapsulating
all the MPI-2 onesided functionality
- Modify the MPI interface functions for the MPI-2 onesided chapter
to properly call the underlying framework and do the required
error checking
- Created an osc component pt2pt, which is layered over the BML/BTL
for communication (although it also uses the PML for long message
transfers). Currently, all support functions, all communication
functions (Put, Get, Accumulate), and the Fence synchronization
function are implemented. The PWSC active synchronization
functions and Lock/Unlock passive synchronization functions are
still not implemented
