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/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.
Updated from master cherry pick: the OFI BTL does not exist on the
v4.0.x branch. Therefore, did not include the OFI BTL changes on
master in this cherry pick.

Similar to #6286 rounding number of bytes into a single precision floating point value to round up the result of a division is a potential risk due to rounding errors.
- remove floating point operations for `round up`
- removes floating point conversion for round down (native behavior of integer division)

This commit fixes a problem reported on the mailing list with
individual writes larger than 512 MB.
The culprit is a floating point division of two large, close values.
Changing the datatypes from float to double (which is what is being
used in the fcoll components) fixes the problem.

The intention of lowering the priority when all processes are local
was to favor Vader BTL. However, in builds including the OFI MTL it
gets selected instead.

PR #5450 addresses MPI_IN_PLACE processing for basic collective algorithms.
But in conjunction with that, we need to check for MPI_IN_PLACE in tuned paths
as well before calling ompi_datatype_type_size() as otherwise we segfault.
MPI spec also stipulates to ignore sendcount and sendtype for Alltoall and
Allgatherv operations. So, extending the check to these algorithms as well.

Change default provider selection logic for the OFI MTL. The
old logic was whitelist-only, so any new HPC NIC provider would
have to ask users to do extra work or wait for an OMPI release
to be whitelisted. The reason for the logic was to avoid
selecting a "generic" provider like sockets or shm that would
frequently have worse performance than the optimized BTL options
Open MPI supports.
With the change, we blacklist the (small, relatively static) list
of providers that duplicate internal capabilities. Users can use
one of thse blacklisted providers in two ways: first, they can
explicitly request the provider in the include list (which will
override the default exclude list) and second, the can set a new
empty exclude list.
Since most HPC networks require special libraries and therefore
an explicit build of libfabric, it is highly unlikely that this
change will cause users to use libfabric when they didn't want to
do so. It does, however, solve the whitelisting problem.
