Ralph Castain a2919174d0 Bring the RML modifications across. This is the first step in a revamp of the ORTE messaging subsystem to support fabric-based communications during launch and wireup phases. When completed, the grpcomm and plm frameworks will each have their own "conduit" for communication - each conduit corresponds to a particular RML messaging transport. This can be the active OOB-based component, or a provider from within the RML/OFI component. Messages sent down the conduit will flow across the associated transport.
Multiple conduits can exist at the same time, and can even point to the same base transport. Each conduit can have its own characteristics (e.g., flow control) based on the info keys provided to the "open_conduit" call. For ease during the transition period, the "legacy" RML interfaces remain as wrappers over the new conduit-based APIs using a default conduit opened during orte_init - this default conduit is tied to the OOB framework so that current behaviors are preserved. Once the transition has been completed, a one-time cleanup will be done to update all RML calls to the new APIs and the "legacy" interfaces will be deleted.

While we are at it: Remove oob/usock component to eliminate the TMPDIR length problem - get all working, including oob_stress
