8db1f89dd1 Small change to allow CUDA-aware to work with non-reduction nonblocking collectives.
Only used when CUDA-aware feature compiled in.

24a7e7aa34 Add support for the udreg registration cache and dynamics on XE/XK/XC.
To support the new mpool two changes were made to the mpool infrastructure:

 1) Added an mpool flag to indicate that an mpool does not need the memory
    hooks to use the leave pinned protocols. This flag is checked in the
    mpool lookup.

 2) Add a mpool context to the base registration. This new member is used
    by the udreg mpool to store the udreg context associated with the
    particular registration. The new member will not break the ABI
    compatibility as the new member is only currently used by the udreg
    mpool.

Dynamics support for Cray systems makes use of the global rank provided by
orte to give the ugni library a unique rank for each process. Dynamics
support is not available under direct-launch (srun.)

c71125acfd Using MPI_* functions in iallreduce can cause comm-spawned processes to
crash. Update libnbc's iallreduce function to use ompi_* functions
instead.

c5596548b2 MPI-3: Add support for neighborhood collectives
Blocking versions are simple linear algorithms implemented in coll/basic. Non-
blocking versions are from libnbc 1.1.1. All algorithms have been tested with
simple test cases.

cb90a4a7fc Add simple algorithms to support MPI_IN_PLACE for MPI_Alltoall, MPI_Alltoallv, and MPI_Alltoallw.
Working on faster algorithms for tuned that will come at a later time.

a3e02fdaff With non-blocking collectives, a "round schedule" could fall on any address
alignment, which typically causes problems on SPARC.  Further, the pointer
manipulation to access elements in a round schedule was clumsy.  This change
introduces macros to facilitate addressing and make it more portable.

0b887ab5a1 * Remove unneeded prototype that was causing compile issues anyway
* Use proper tag space (the negatives below the blocking communicators)
  instead of the point-to-point space
* Use the PML interface instead of the MPI interface, since the MPI
  interface 1) shouldn't be used by components and 2) doesn't like
  negative tags
