Extend the regular expression parsing support
Do a little cleanup - only resusage needs the node/proc info, so remove it from the sensor base
Minor cleanup of the node state definitions - using the enum allows the debuggers to pretty-print the value
Restore locality computation to the nidmap code - don't know how/when it was removed, but that was not good
