Fix resource usage tracking for map/bind operations
Tracking solely at the slot level doesn't adequately protect against overlapping CPU assignments and other more complex mapping requests. Modify the resource usage tracking to operate at the CPU level and combine the mapping/binding operation into a single pass. Ranking must still be done as a second pass, but restrict the options to simplify implementation and avoid confusion. Update the help output to reflect the changes. Allow the DVM to also support "do-not-launch" directives for testing purposes, and to accept simulated node/topologies. Fix a few other minor problems along the way.
