e865a751bd * First whack at making the onesided component endian safe. Needs a endian-safe
datatype engine to really give it a whirl ;).

285581dff2 More endian-related cleanups:
- 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

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
