Corrected the signatures of the collectives used by the Fortran 2008
interface to state correct intent for inout arguments and use the
ASYNCHRONOUS attribute in non-blocking collective calls.

ASYNCHRONOUS attribute in non-blocking collective calls. Also corrected
the C-bindings in Fortran accordingly

Specifically mention our intended behavior about /usr and /usr/lib
(and why we don't add /usr/lib[64] and /usr/local/lib[64] to RPATH).

Implements recursive doubling algorithm for MPI_Iexscan.
The algorithm preserves order of operations so it can be used both
by commutative and non-commutative operations.
The MCA parameter 'coll_libnbc_iexscan_algorithm' was added for dynamic
algorithm selection.

Fix the test that determined whether we output "writeable" or
"read-only" for MCA vars (it was checking the wrong flag).

Disable async receive for CUDA under OpenIB. While a performance
optimization, it also causes incorrect results for transfers
larger than the GPUDirect RDMA limit. This change has been validated
and approved by Akshay.

- do not generate bindings for pompi_FOO_f symbols
(they are simply not used anywhere)
- move ompi_FOO_f bindings out of mpi_f08.mod into
ompi_mpifh_bindings.mod that is only used at build time

We previously needed to have empty targets because AM couldn't handle
having an AM_CONDITIONAL was targets in the "if" statement but not in the
"else". :-(
That now appears as an old automake bug that has been fixed,
so cleanup some Makefile.am
Thanks Jeff for the pointer.

The parameter passed to NBC_Return_handle() was incorrectly casted
and not dereferenced.

This can be returned when running on QEMU user-mode emulation,
which does not support getsockopt with SO_RCVTIMEO.

The embedded PMIx Automake minimum version is already 1.13.4, so to
autogen.pl Open MPI successfully, you already have to have Autoamek
1.13.4. So we might as well make it official (i.e., bump Open MPI's
Automake minimum to match the Automake minimum in the embedded PMIx).
