New "app ops" service.
Initial implementation, tracking use of the vibrator, GPS,
and location reports.
Also includes an update to battery stats to also keep track of
vibrator usage (since I had to be in the vibrator code anyway
to instrument it).
The service itself is only half-done. Currently no API to
retrieve the data (which once there will allow us to show you
which apps are currently causing the GPS to run and who has
recently accessed your location), it doesn't persist its data
like it should, and no way to tell it to reject app requests
for various operations.
But hey, it's a start!
