Ralph Castain 5120e6aec3 Redefine the rmaps framework to allow multiple mapper modules to be active at the same time. This allows users to map the primary job one way, and map any comm_spawn'd job in a different way. Modules are given the opportunity to map a job in priority order, with the round-robin mapper having the highest default priority. Priority of each module can be defined using mca param.
When called, each mapper checks to see if it can map the job. If npernode is provided, for example, then the loadbalance mapper accepts the assignment and performs the operation - all mappers before it will "pass" as they can't map npernode requests.

Also remove the stale and never completed topo mapper.
