Ralph Castain f139cfd28a Fully enable the use of static ports to minimize connections on mpirun. When static ports are provided, daemons will automatically use routes defined by the selected routed module to callback to mpirun during startup, thus elimating the dedicated daemon-to-mpirun connection. Therefore, the total number of connections on mpirun will equal the fanout of the routed module (instead of #nodes in job).
Add a new tm ess module that exploits this capability.

Update the various plm modules to enable it - just a minor change reflecting an added param to a plm base function.

Additional fixes included:

1. remove an erroneous cleanup of session directories in the tool finalize procedure - tools don't create session directories to begin with!

2. fix a duplicate free when attempting to execute a non-existent app

3. cleanup an typo in the comm utilities 

4. fix comm_spawn - was perturbed by the changes in pack/unpack of orte_job_t to properly support orte-ps

Been tested on slurm and tm machines, using all tests in orte/test/mpi. May run into issue with command line length on large jobs due to inclusion of node info to support static ports - will fix this next with addition of regexp generator to compress that info.

This commit was SVN r21248.
