Ralph Castain 9a57db4a81 To support comm_spawn in fully routed environments, daemons need to know the route to all procs in their job family. They already had this information, but were not retaining it. The infrastructure to do so has existed for some time - just never had the time to complete it.
This commit does that by ensuring that daemons retain knowledge of proc location for all procs in their job family. It required a minor change to the ESS API to allow the daemons to update their pidmaps as data was received. In addition, the routed modules have been updated to take advantage of the newly available info, and the encode/decode pidmap utilities have been updated to communicate the required info in the launch message.

This commit was SVN r20022.
