Ralph Castain	98580c117b	Introduce staged execution. If you don't have adequate resources to run everything without oversubscribing, don't want to oversubscribe, and aren't using MPI, then staged execution lets you (a) run as many procs as there are available resources, and (b) start additional procs as others complete and free up resources. Adds a new mapper as well as a new state machine. ... Remove some stale configure.m4's we no longer need. Optimize the nidmaps a bit by only sending info that has changed each time, instead of sending a complete copy of everything. Makes no difference for the typical MPI job - only impacts things like staged execution where we are sending multiple (possibly many) launch messages.

Ralph Castain	431d5361ed	For those who really preferred our prior mode of operation that mapped procs and only launched daemons on the nodes that had procs on them, introduce the "novm" state machine component. This recreates the old mode of operation by re-ordering the launch sequence so that we allocate, then map, and then launch daemons only on the reqd nodes (instead of across the entire allocation). ...
