More procstats work: separate global proc account, more dumping.

We now keep track of the time actually process run independently
of the time packages run in process, so we can give an accurate
summary of how long each physical process runs.

New command line options can be supplied to restrict printing to
a specific package, dump in a new csv format, control what is
printed in the csv format, and print a checkin report.

Add toString methods to ArrayMap and ArraySet.
