44d13b0bab * add a bunch of (currently disabled) debugging output statements
* fix a silly bug where we weren't adding a long accumulate message to
  the pending long messages list, so we hung if a long accumulate
  occurred.  Still having some memory issues on one of the tests I'm
  running - need to move over to Linux and Valgrind after some sleep.

This commit was SVN r9108.

eb7e722588 * clean up some of the debugging in the onesided code so that I can understand
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 :)

ec7b60d501 * Fix some error checking code for Lock / Unlock at the MPI layer
* Implement win_lock and win_unlock in the pt2pt component.  Not well
  tested, but appears to move bits if properly motivated...

340bf14191 * support non-predefined datatypes for all three communication mechanisms
* 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...

44a516d966 * Clean up error checking in the MPI interface for MPI-2 onesided
* 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

762fe70bd1 * Fix uninitialized variable warning. Technically, start's group should be
a subset of win's group, so this should never happen.  But users have
  been known to screw up before, so return a reasonable error.

b1d2424013 Merge in present work on the MPI-2 onesided chapter. The current code is not
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
