place things are single threaded. OFI providers may start spawn threads,

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).

Adds the capability to select a NIC based on hardware locality.
Creates a list of NICs that share the same cpuset as the process,
then selects the NIC based on the (local rank) % (number of NICs).
If no NICs are available that share the same cpuset, the selection process
will create a list of all available NICs and make a selection based on
(local rank) % (number of NICs)

Change ompi_mtl_ofi_get_endpoint() to call the active PML's
add_procs() rather than the OFI MTL add_procs() directly when
discovering a new process during operation.
Functionally, this has no impact in correct operation. However,
the current behavior means that the heterogenous and active PML
checks are not being executed in the dynamic discovery case.

This fix is from John L. Byrne (john.l.byrne@hpe.com).
When OFI Libfabric binds objects to endpoints, before the object can
be successfully closed, the endpoint must first be freed. For scalable
endpoints, objects can also be bound to transmit and receive contexts,
and for objects that are bound to contexts, we need to first free the
contexts before freeing the endpoint. We also need to clear the memory
registration cache.
If we don't clean up properly, then fi\_close may not be able to close
the domain because the dom will have a non-zero ref count.

Some versions of Libfabric contain a bug in EFA where FI_REMOTE_COMM and
FI_LOCAL_COMM are not advertised. In order to workaround this, we need to call
fi_getinfo() without those capability bits to see if EFA is available first.
Also move around some of the provider include/exclude list logic so we can skip
this workaround if applicable.

Make sure to get an RDM provider that can provide both local and
remote communication. We need this check because some providers could
be selected via RXD or RXM, but can't provide local communication, for
example.
Add OPAL_CHECK_OFI_VERSION_GE() m4 macro to check that the Libfabric
we're building against is >= a target version. Use this check in two
places:
1. MTL/OFI: Make sure it is >= v1.5, because the FI_LOCAL_COMM /
FI_REMOTE_COMM constants were introduced in Libfabric API v1.5.
2. BTL/usnic: It already had similar configury to check for Libfabric
>= v1.1, but the usnic component was checking for >= v1.3. So
update the btl/usnic configury to use the new macro and check for
>= v1.3.

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.

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.

processes is more than available contexts. This fixes issue #6182.

1. __STDC_VERSION__ isn't necessarily defined (e.g., by C++
compilers). So check to make sure it is defined before we actually
check the value.
2. If we're in C++11 (or later), use static_assert().
3. Split the static assert macro in two macros:
* THIS_SYMBOL_WAS_REMOVED_IN_MPI30(...): Insert a valid expression
(i.e., 0, because it's only used with MPI_Datatype values, and
since MPI_Datatype is a pointer, 0 is a valid RHS expression)
before invoking the static assert so that we don't get a syntax
error instead of the actual static assert error.
* THIS_FUNCTION_WAS_REMOVED_IN_MPI30(...): No need for the valid
expression; just invoke the assert functionality.
Also remove an errant "\".
Thanks to Constantine Khrulev and Martin Audet for identifying the
issue and suggesting to use C11's static_assert().
