also add common verbose variable.
Note the verbosity thing is a little tricky owing to the way the MCA frameworks and components are registered and
and initialized. The BTL's are registered/initialized prior to the MTL components even getting registered.

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)

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.

The 2 sided communication support is added for non-tagmatching provider
to take advantage of this BTL and PML OB1. The current state is
"functional" and not optimized for performance.
Two sided support is disabled by default and can be turned on by mca
parameter: "mca_btl_ofi_mode".

This commit added new transport layer to be used with osc rdma module.
This BTL provides put, get, atomic and fetch atomic operations. It can
be used with multiple hardware vendors as long as they have their
provider under Libfabric and have the right capabilities.
