Ralph Castain 7c7304466c Add a binomial tree-based launch to ssh, turned "on" only when the plm_rsh_tree_spawned mca param is set to a non-zero value. This probably isn't a very optimized capability, but it does execute a tree-based launch that may scale better than linear at high node counts.
Add the daemon map capability to the ODLS to create and save a map of daemon vpid vs nodename from the launch message.

Cleanup a few places in the base plm launch support where we didn't adequately protect rml recv's from potentially executing sends.

This commit was SVN r18143.
