Ralph Castain f014284f91 Update resilient recovery mapping algorithm to be a bit more sophisticated. Track the prior node a proc was on so we avoid ricochet effect. Also avoid putting recovering proc onto node that is already occupied by a peer as this degrades fault tolerance. ...

Test to ensure that num_procs was provided for the resilient mapper - it cannot be used with options like npernode.

WARNING: Work on the temp branch being merged here encountered problems with bugs in subversion. Considerable effort has gone into validating the branch. However, not all conditions can be checked, so users are cautioned that it may be advisable to not update from the trunk for a few days to allow MTT to identify platform-specific issues.

rmaps_resilient_component.c

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.

rmaps_resilient.h

Add a resilient mapping capability - currently maps by fault groups (if provided), still need to add the remapping capability for failed procs.
