Brian Barrett 39a6057fc6 A number of improvements / changes to the RML/OOB layers:
* General TCP cleanup for OPAL / ORTE
  * Simplifying the OOB by moving much of the logic into the RML
  * Allowing the OOB RML component to do routing of messages
  * Adding a component framework for handling routing tables
  * Moving the xcast functionality from the OOB base to its own framework

Includes merge from tmp/bwb-oob-rml-merge revisions:

    r15506, r15507, r15508, r15510, r15511, r15512, r15513
