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.

1. completely and cleanly separates responsibilities between the HNP, orted, and tool components.
2. removes all wireup messaging during launch and shutdown.
3. maintains flow control for stdin to avoid large-scale consumption of memory by orteds when large input files are forwarded. This is done using an xon/xoff protocol.
4. enables specification of stdin recipients on the mpirun cmd line. Allowed options include rank, "all", or "none". Default is rank 0.
5. creates a new MPI_Info key "ompi_stdin_target" that supports the above options for child jobs. Default is "none".
6. adds a new tool "orte-iof" that can connect to a running mpirun and display the output. Cmd line options allow selection of any combination of stdout, stderr, and stddiag. Default is stdout.
7. adds a new mpirun and orte-iof cmd line option "tag-output" that will tag each line of output with process name and stream ident. For example, "[1,0]<stdout>this is output"
This is not intended for the 1.3 release as it is a major change requiring considerable soak time.
This commit was SVN r19767.
