Ralph Castain 01ba861f2a When direct launching applications, we must allow the MPI layer to progress during RTE-level barriers. Neither SLURM nor Cray provide non-blocking fence functions, so push those calls into a separate event thread (use the OPAL async thread for this purpose so we don't create another one) and let the MPI thread sping in wait_for_completion. This also restores the "lazy" completion during MPI_Finalize to minimize cpu utilization. ...

Update external as well

Revise the change: we still need the MPI_Barrier in MPI_Finalize when we use a blocking fence, but do use the "lazy" wait for completion. Replace the direct logic in MPI_Init with a cleaner macro

pmix_s2_component.c

Fix singleton operations when running under a SLURM allocation. Sadly, SLURM's PMI will return success even if the PMI server isn't actually available. This leads to erroneous selection of pmix and ess components. So add a further requirement (namely, that we see a job_step envar) to the SLURM pmix components along with some modification of ess selection code to avoid the problem
