f4411c4393 Enable use of OFI fabrics for launch and other collective operations. Update the PMIx repo to the latest master to get the required support for the server to "push" modex info, and to retrieve all its own "modex" values for sending back to mpirun. Have mpirun cache them in its local modex hash as OFI goes point-to-point direct and doesn't route - so the remote daemons don't need a copy of this connection info. 
Remove the opal_ignore from the RML/OFI component, but disable that component unless the user specifically requests it via the "rml_ofi_desired=1" MCA param. This will let us test compile in various environments without interfering with operations while we continue to debug

952726c121 Update to latest PMIx master - equivalent to 2.0rc2. Update the thread support in the opal/pmix framework to protect the framework-level structures. 
This now passes the loop test, and so we believe it resolves the random hangs in finalize.

Changes in PMIx master that are included here:

* Fixed a bug in the PMIx_Get logic
* Fixed self-notification procedure
* Made pmix_output functions thread safe
* Fixed a number of thread safety issues
* Updated configury to use 'uname -n' when hostname is unavailable

Work on cleaning up the event handler thread safety problem
Rarely used functions, but protect them anyway
Fix the last part of the intercomm problem
Ensure we don't cover any PMIx calls with the framework-level lock.
Protect against NULL argv comm_spawn

206aec6083 By default, apply signals to all direct children _and_ any children they might have spawned (so long as they remain in the same process group). Provide an MCA param (odls_base_signal_direct_children_only) to indicate that the signal is to go _only_ to our direct children, and not be delivered to any children spawned by those procs.

919d7fcf49 We cannot use OFI to determine when daemons can finalize as we don't see the "sockets" go away. So always use the OOB for the mgmt conduit - this provides the necessary termination signal AND ensures that IOF and other mgmt messages go solely across TCP. 
Cleanup the way we look for matching OFI addresses by using the opal_net_samenetwork helper function. This now works for multi-network environments, but only using the socket provider
