Enable one mpirun to act as the server for another mpirun when doing MPI_Publish_name and its associated operations. The user is responsible, of course, for ensuring that the mpirun acting as a server outlives any mpiruns using it in that capacity. Add a cmd line option to mpirun --report-pid that prints out mpirun's pid. Allow the --ompi-server option to now take pid:# (or PID:#) of the mpirun to be used as the server, and then look that pid up by searching the local mpirun contact infos for it. This commit was SVN r20102.
