Add changes to have the ability to turn on and off the
automatic light sensing for the device. This is fully configurable
and is by default not present. Vendors should override the ALS setting
to enable the automatic lighting controls.
These changes will add a check box to the Brightness settings menu to give control
to the user to allow the device's display lighting to be controlled via the slide bar
or the auto lighting system.
If the user selects auto then the slide bar will become invisible. Manual mode
will present the slide bar to the user.

A timeout of 0 could cause the vibration thread to run with a null pattern and
crash the system server. Instead, we should just ignore vibrations that don't
make any sense (similar to ignoring a bad pattern vibration).
There are 2 types of vibrations: simple and repeated. Simple vibrations run for
a given length of time while repeated patterns run until canceled or the calling
process dies.
If a vibration is currently running and another request is issued, the newer
request always takes precedence unless the current vibration is a simple one and
the time left is longer than the new request.
If a repeating vibration is running and a new request overrides that vibration,
the current vibration is pushed onto a stack. Once the new vibration completes,
the previous vibration resumes. IBinder tokens are used to identify Vibration
requests which means that multiple calls to Vibrator.vibrate with the same
Vibrator object will override previous vibrations on that object.
Adds stats for:
- Number of raw user events that have happened in the system.
- Number of times user activity has been reported, dividied by UID and type of activity.
- Duration of screen brightness levels in 4 buckets.
- Per-UID tracking of who has turned on Wifi and how long we can attribute it being on because of them.
