* Make sure that the pval always writes to the correct portion of the
lval. This only matters on 32 bit big endian machines.
* On 32 bit machines when assigning to pval, the other 4 bytes of lval
weren't being written, which could lead to bogus data
We use macros so that there aren't casts all over the code and the pval
assignment can occur to the correct 4 bytes. Refs trac:587

I do something else" rule screws me up again. If we're in a FENCE, but
not in ACCESS | EXPOSE, put us in ACCESS|EXPOSE, as we are now known we
now in a real Fence epoch. Yay silly MPI standards

we were reusing data structures between PW and SC. Instead, we now
have explicit post_msg and complete_msg counters for completion.

* Only register the rdma osc callback once, as it turns out that some
btls (MX) do somethng more than update a table during the register
call, and each register call sucks up valuable fragments...

long ago) supposed to be used as a cache for accessing the PML procs. But in
all of the PMLs the PML proc contain only one field i.e. a pointer to the ompi_proc.
This pointer can be accessed using the c_remote_group easily. Therefore, there is no
meaning of keeping the PML procs around. Slim fast commit ...

* Print a warning error message if a target is not in an exposure epoch

one-sided interface even when we are using the CM PML and MTLs for
point-to-point transport (and therefore not using the BML/BTLs)

completely safe, so it must be explicitly enabled by the user, either with

what is going on
* Fix a dumb error where if a lock was released and another was pending, I
would send a lock *request* to the queued process, rather than giving
him the lock and sending him a lock *ack*. Turns out requests and
acks are different things :)
This commit was SVN r9103.
* Implement win_lock and win_unlock in the pt2pt component. Not well
tested, but appears to move bits if properly motivated...
This commit was SVN r8922.
* rework the thread locking so that it at least makes sense to me. Still
need to do a bunch of testing before I'm happy with it, but it's a tad
bit closer...
This commit was SVN r8918.
* 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
