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.

This commit changes values of existing `OMPI_DATATYPE_MPI_*` macros.
This change does not affect ABI compatibility of `libmpi.so` and the

On the other hand, `ompi_datatype_t::id` values of existing datatypes

The type `short float` is proposed for the C language in ISO/IEC JTC
1/SC 22 WG 14 (C WG) for mainly IEEE 754-2008 binary16, a.k.a.
half-precision floating point or FP16.
By this commit, `short float` and `short float _Complex` are detected
in `configure` and used in Open MPI internal code. `MPI_SHORT_FLOAT`
and its complex number version are not added yet.

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.

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)

Moving to a model where we have users actively _enable_ SEP feature for use
rather than opening SEP by default if provider supports it. This allows us to
not regress (either functionally or for performance reasons) any apps that were
working correctly on regular endpoints.
Also, providing MCA to specify number of OFI contexts to create and default
this value to 1 (Given btl/ofi also creates one by default, this reduces the
incidence of a scenario where we allocate all available contexts by default and
if btl/ofi asks for one more, then provider breaks as it doesn't support it).
While at it, spruce up README on SEP content.

generate-opt-funcs.pl to generate specialized functions for

-> Added new perl module *.pm files for send,isend,irecv,iprobe,improbe
which are loaded by generate-opt-funcs.pl to create new source files
that correspond to the name of the .pm file to be used as part of
MTL OFI.
-> Added mtl_ofi_opt.pm.template and updated README with details on the
specialization features and how to add additional specialization
support.
-> Added new opt_common/mtl_ofi_opt_common.pm containing common
functions for generating the specialized functions used by
all other *.pm modules.
-> Added new mtl_ofi.h which includes the definitions for the
function symbol table for storing the specialized functions along
with the definitions for the initialization functions for the
corresponding function pointers.
-> Based off the OFI provider capabilities the specialized function
pointers are assigned at mtl_ofi_component_init to the corresponding
MTL OFI function.
-> mca_mtl_ofi_module_t has been updated with the symbol table
struct which is assigned at component init.

For cases when the number of local processes is greater than the number of
available contexts, the SEP initialization phase would calculate the number of
contexts to provision for each rank to be 0 and would eventually crash.
Fix the issue here by using regular endpoints in the event the number of local
processes is more than available contexts. This fixes issue #6182.

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