bugfix: provider selection would not differentiate between ipv4
and ipv6 addresses which would cause some nodes to be unable
to communicate between each other. Adding a check for address
format to provider selection to ensure that all nodes use the
same address format.

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.
Here's the change in ofi mtl mca parameters. Before commit:
MCA mtl ofi: parameter "mtl_ofi_provider_include" (current value: "psm2", data source: environment, level: 1 user/basic, type: string)
Comma-delimited list of OFI providers that are considered for use (e.g., "psm,psm2"; an empty value means that all providers will be considered). Mutually exclusive with mtl_ofi_provider_exclude.
MCA mtl ofi: parameter "mtl_ofi_provider_exclude" (current value: "shm,sockets,tcp,udp,rstream", data source: default, level: 1 user/basic, type: string)
Comma-delimited list of OFI providers that are not considered for use (default: "sockets,mxm"; empty value means that all providers will be considered). Mutually exclusive with mtl_ofi_provider_include.
After commit:
MCA btl ofi: parameter "btl_ofi_provider_include" (current value: "", data source: default, level: 1 user/basic, type: string, synonym of: opal_common_ofi_provider_include)
Comma-delimited list of OFI providers that are considered for use (e.g., "psm,psm2"; an empty value means that all providers will be considered). Mutually exclusive with mtl_ofi_provider_exclude.
MCA btl ofi: parameter "btl_ofi_provider_exclude" (current value: "shm,sockets,tcp,udp,rstream", data source: default, level: 1 user/basic, type: string, synonym of: opal_common_ofi_provider_exclude)

MCA mtl ofi: parameter "mtl_ofi_provider_exclude" (current value: "shm,sockets,tcp,udp,rstream", data source: default, level: 1 user/basic, type: string, synonym of: opal_common_ofi_provider_exclude)
Comma-delimited list of OFI providers that are not considered for use (default: "sockets,mxm"; empty value means that all providers will be considered). Mutually exclusive with mtl_ofi_provider_include.
MCA mtl ofi: parameter "mtl_ofi_verbose" (current value: "0", data source: default, level: 3 user/all, type: int, synonym of: opal_common_ofi_verbose)

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)

As discussed in open-mpi/ompi#2519 the common component does not depend
on libfabric yet. This commit introduces this dependency by just calling
fi_version().

This PR renames the common library for OFI libfabric from
libfabric to ofi. There are a number of reasons this
is good to do:
1) its shorter and replaces 9 characters with three for
function names for what may eventually be a fairly extensive interface
2) OFI is the term used for MTL and RML components that use
the OFI libfabric interface
3) A planned OSC component will also use the OFI term.
4) Other HPC libraries that can use OFI libfabric tend to use
the term "ofi" internally and also in their configure options
relevant to OFI libfabric (i.e. MPICH/CH4, Intel MPI, Sandia SHMEM)
There seem to be comments in places in the Open MPI source
code that indicate that this common library will be going away.
Far from it as we will want to be able to share things like
AV objects between OMPI and possibly OSHMEM components that
use the OFI libfabric interface.
This PR also adds a synonym to the --with-libfabric(-libdir)
configury options: --with-ofi and with-ofi-libdir.
