Ralph Castain 4636125e2d Modify the RMGR components to allow job setup with a given jobid, and add another attribute so that we can setup triggers without launching.
Add some debugging output to the ODLS default module, and the orted.

Remove the nodename data from the ODLS info report - that info is already stored in the registry by the RMAPS framework upon completing the mapping procedure.

Add another test program that does an ORTE-only dynamic spawn (gasp!). Looks just like comm_spawn - just no MPI involved.

Modify the ODLS to release the processor when we "kill" local procs in a more scalable fashion. It previously had a sleep in it that Jeff's prior commit removed. However, he introduced some Windows code into the non-Windows component (protected by "if"s, but unnecessary). This is a more general solution he proposed - included here so I could get things to compile properly.

This commit was SVN r12579.
