For the non thread-grouping paths, only the first (0th) OFI context
should be used for communication. Otherwise this would access a non existant
array item and cause segfault.
While at it, clarifiy some content regarding SEPs in README (Credit to Matias Cabral

Update the OPAL_CHECK_OFI configury macro:
- Make it safe to call the macro multiple times:
- The checks only execute the first time it is invoked
- Subsequent invocations, it just emits a friendly "checking..."
message so that configure output is sensible/logical
- With the goal of ultimately removing opal/mca/common/ofi, rename the
output variables from OPAL_CHECK_OFI to be
opal_ofi_{happy|CPPFLAGS|LDFLAGS|LIBS}.
- Update btl/ofi, btl/usnic, and mtl/ofi for these new conventions.
- Also, don't use AC_REQUIRE to invoke OPAL_CHECK_OFI because that
causes the macro to be invoked at a fairly random time, which makes
configure stdout confusing / hard to grok.
- Remove a little left-over kruft in OPAL_CHECK_OFI, too (which
resulted in an indenting change, making the change to
opal_check_ofi.m4 look larger than it really is).
Thanks Alastair McKinstry for the report and initial fix.
Thanks Rashika Kheria for the reminder.

Now that all use of libibverbs is gone from Open MPI, and all
verbs-based configury is also removed, update README to remove all
references to --with-verbs.
Signed-off-by: Jeff Squyres <jsquyres@cisco.com>
Now that all components that use libibverbs are gone, remove
OPAL_CHECK_VERBS and the confusingly-named OPAL_CHECK_OPENFABRICS
(which really just checked for verbs things -- not all the possible
OpenFabrics APIs/libraries).
The only code left in Open MPI that calls verbs is hwloc -- and that's
just the APIs that takes an IBV device and returns topological
information about it. Since nothing in the Open MPI code base uses
the "ibv_*" API any more, we have no need for this hwloc functionality
so we'll even remove the --with-verbs configure options.

So long sshmem/verbs! After many years of (mostly) faithful service,
it is time to remove the sshmem verbs component. It has been fully
replaced by other components, such as the UCX PML and OFI MTL.

PMIx is removing the --enable-embedded-libevent and
--enable-embedded-hwloc flags as they are confusing users. Instead, we
will use the --enable-embedded-mode to handle both of these options.
Update the embedded configury to handle it.

It doesn't seem like the BTL was using uninitialized pointer. But simply
setting the rcache pointer to NULL after destroying it makes the valgrind
errors go away.

The issue was a little complicated due to the internal stack used in the
convertor. The main issue was that in the case where we run out of iov
space to save the raw description of the data while hanbdling a
repetition (loop), instead of saving the current position and bailing out
directly we reading of the next predefined type element. It worked in
most cases, except the one identified by the HDF5 test. However, the
biggest issue here was the drop in performance for all ensuing calls to
the convertor pack/unpack, as instead of handling contiguous loops as a
whole (and minimizing the number of memory copies) we copied data
description by data description.

When compiling mpi.h with a modern C++ compiler and a high degree of
pickyness (e.g., -Wold-style-cast), casting using (void*) in the
OMPI_PREDEFINED_GLOBAL and MPI_STATUS*_IGNORE macros will emit
warnings. So if we're compiling with a C++ compiler, use C++'s
static_cast<> instead of (void*).
Thanks to @shadow-fax for identifying the issue.

This commit fixes a bug introduced in
f62d26ddbc8cda4d985cceee531a2ec32406d1f6. That commit changed how
vader allocates fragment memory from the shared memory
segment. Unfortunately, the values used for the fragment sizes did not
include space for the fragment header. This can cause an overrun of
data from one fragment to the header of the next fragment.

Some macros defined by the embedded hwloc ends up in opal_config.h
because hwloc configury m4 files are slurped into Open MPI. These
macros are not required here, and they might conflict with an external
hwloc install, so simply #undef them in hwloc/external/external.h
after including <opal_config.h> but before including the external
<hwloc.h>.

ACCUMULATE, unlike REDUCE, can use with derived
datatypes with predefinied operations, with some
restrictions outlined in MPI-3:11.3.4. The derived
datatype must be composed entierly from one predefined
datatype (so you can do all the construction you want,
but at the bottom, you can only use one datatype, say,
MPI_INT).
