Get the direct routed component to work with both TCP and USOCK OOB components. We previously had setup the direct component so it would only support direct-launched applications. Thus, all routes went direct between processes. However, if the job had been launched by mpirun, this made no sense - what you wanted instead was to have each app proc talk directly to its daemon, but have the daemons all directly connect to each other.
...
So we need all the routing code for dealing with cross-job communications, lifelines, etc. The HNP will be directly connected to all daemons as they must callback at startup, and so we need to track those children correctly so we know when it is okay to terminate.
We still have to support direct launch, though, as this is the only component we can use in that scenario. So if the app doesn't have daemon URI info, then it must fall back to directly connecting to everything.

Fix a couple of minor issues. Ensure usock isn't used if the session dirs aren't setup. Protect an oddball case where orte_xml_fp is NULL.

Re-enable the usock oob component. Ensure the TCP component promotes messages for other procs to the OOB base so that other components have a chance to send the relay. Seems to be passing MTT, so let's see how it works for others.

Add unix socket component to OOB - no longer require active network for local operations. Demonstrate inter-transport crossover.

VERY tentatively schedule this for 1.7.5 - only to be applied if we see no troubles AND the branch is ready in advance.

Enable use of unix domain sockets for local OOB communications, thereby removing the requirement for an active network interface when running strictly on a single node. Update the overall OOB system to support cross-transport movement of messages so that the OOB can move a received message to another transport for transmission.
