Also fix a bug where, when parceling the stats, we were
computing the final duration values too late. We need to
do that before we write the long table.

ProcessStats is now called ProcessCpuTracker.
ProcessTracker is now ProcessStatsService, and its inner State

This ProcessStats is moved to the framework, so we will be able
to use it elsewhere.
