Ralph Castain a4c8e8c28a Cleanup the proposed change: 
* qos framework is moving to the scon layer and is no longer required in ORTE

* remove the rml/ftrm component as we now have multiple active components, and so the wrapper needs to be rethought

* no need for separating the "base" from "API" module definition. The two are identical

* move the "stub" functions into their own file for cleanliness

* general cleanup to meet coding standards

* cleanup some logic in the stubs
