38b0d22243 Some cleanups to the pt2pt component
* Remove unused declaration
  * remove unused variable warning when not using progress threads
  * If we're using progress threads, we want to lock, not trylock
    when in progress, since it was called from the wakeup thread
    and not the progress function

This commit was SVN r14739.

2b4b754925 Some much needed cleanup of the point-to-point one-sided component...
* 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.

63e5668e29 Number of one-sided fixes:
* 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

14f338b7df Fix for lock/unlock epoch issues. Previously, we did not handle the case
where a window was in both the passive and active side of a lock sequence.

8fc278c3a3 Rest of the fix for #325. It uses a bit more space, but now we can reasonably
tell if the remote proc should be in an exposure epoch or not.

0ba0a60ada * Merge in new version of the pt2pt one-sided communication component,
implemented entirely on top of the PML.  This allows us to have a
  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)
* Old pt2pt component was renamed "rdma", as it will soon be having
  real RDMA support added to it.

Work was done in a temporary branch.  Commit is the result of the

d5e0ea3590 * Post and Start should only check their epoch types for conflicts, otherwise
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...

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

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
