This commit updates osc/pt2pt to allocate peer object as they are
needed rather than all at once. Additionally, to help improve the
memory footprint a new synchronization structure has been added.

* Combine polling of the long requests and buffer requests into
one type, and in one place
* Associate the list of requests to poll with the component, not
the individual modules
* add progress thread that sits on the OMPI request structure
and wakes up at the appropriate time to poll the message
list. Not the best, but without some asynch notification
from the PML that a given set of requests has completed, there
isn't much better
* Instead of calling opal_progress() all over the place, move
to using the condition variables like the rest of the project.
Has the advantage of moving it slightly futher along in the
becoming thread safe thing
* Fix a problem with the passive side of unlock where it could
go recursive and cause all kinds of problems, especially
when progress threads are used. Instead, have two parts of
passive unlock -- one to start the unlock, and another to
complete the lock and send the ack back. The data moving
code trips the second at the right time.

replied that the window is unlocked.

- moved hton64 and ntoh64 from the bunch of places it had been copied
into one header file
- properly set and use the btl_tcp's nbo option to put things in
network byte order on the wire if both sides don't have the same
endianness
- Put the OB1 PML's headers (with a couple exceptions I need to discuss
with Tim) in network byte order on the wire if both sides don't have
the same endianness
- since it was needed for the TCP BTL, move the orte_process_name_t
HTON and NTOH macros from the TCP OOB to ns_types.h

* 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
