Now the per-package proc stats data is also per-app-version-code.
In addition to changing the data structure to have one more
SparseArray and passing a version code all over, this also required
improving how we reset the stats so that we can prune a multi-package
process record back to a single package. Otherwise, as you install
updates to apps, the proc stats data would continue to explode as
the data for each of those app's processes got turned to a
multi-package due to tracking the old and new versions at the
same time.
This also bumps the checkin version code, since the package entries
also include a new field for the app version code.
