This commit expands the OPAL_THREAD macros to include 32- and 64-bit
atomic swap. Additionally, macro declararations have been updated to
include both OPAL_THREAD_* and OPAL_ATOMIC_*. Before this commit the
former was used with add and the later with cmpset.

This commit fixes typos on the C side of the request-based RMA binding. We
were not returning the request on success but on failure. Thanks to
@alazzaro for reporting and @ggouaillardet, and @vondele for tracking
this down.
Fixes part of open-mpi/ompi#1869

This commit introduces a new algorithm for MPI_Comm_split_type. The
old algorithm performed an allgather on the communicator to decide
which processes were part of the new communicators. This does not
scale well in either time or memory.
The new algorithm performs a couple of all reductions to determine the
global parameters of the MPI_Comm_split_type call. If any rank gives
an inconsistent split_type (as defined by the standard) an error is
returned without proceeding further. The algorithm then creates a
communicator with all the ranks that match the split_type (no
communication required) in the same order as the original
communicator. It then does an allgather on the new communicator (which
should be much smaller) to determine 1) if the new communicator is in
the correct order, and 2) if any ranks in the new communicator
supplied MPI_UNDEFINED as the split_type. If either of these
conditions are detected the new communicator is split using
ompi_comm_split and the intermediate communicator is freed.

This commit simplifies the communicator context ID generation by
removing the blocking code. The high level calls: ompi_comm_nextcid
and ompi_comm_activate remain but now call the non-blocking variants
and wait on the resulting request. This was done to remove the
parallel paths for context ID generation in preperation for further
improvements of the CID generation code.

the coll_array functions are truly only used by the fcoll modules, so move
them to fcoll/base. There is currently one exception to that rule (number of aggreagtors
logic), but that function will be moved in a long term also to fcoll/base.
This commit fixes a bug in the RDMA compare-and-swap implementation
that caused the origin value to always be written even if the compare
should have failed.
