Jeff Squyres 628125599d Fix the TCL btl module endpoint matching during setup for the scenario
when running an MPI job spanning a node that has two TCP NICs and a
node that has one TCP NIC.  Previously, for the 2 NIC/module process,
we would return the first peer IP address if we couldn't find a subnet
match with any of the peer's published IP addresses -- this was to
support running OMPI across subnet boundaries.  Changed the behavior
to only do that behavior if the IP address we're trying to match is
public (i.e., not 10.x.y.z, 192.168.x.y, or 172.16.x.y) *and* any of
the remote peer's addresses are public (working on the assumption that
if we both have public addresses, they're routable to each other).

This definitely will not work in all scenarios, such as when we go to
WAN kinds of executions, and will need to be revisited at that time.

This commit was SVN r9119.
