Call noteWifiScanStartedFromSource() when a scan is started.
Call noteWifiScanStoppedFromSource() when a scan is finished.
The current implementation tracks to UID that requested the scan, and
correctly tracks the duration of the scan. It ignores scan requests
that occur when a scan is already in progress. It does not distinguish
between active and passive scans.
Repurpose all the noteScanWifiLockAcquired/Released() plumbing
for WIFI scan tracking. The WIFI scan locks were never reported
to the user. Use noteFullWifiLock() when WIFI scan locks are used -
this makes sense because the power draw for a WIFI scan lock
should be about the same as for a full WIFI lock.

Replace TrafficStats calls by reading values from xt_qtaguid kernel
module. To keep BatteryStatsImpl changes lightweight, cache recently
parsed stats. Tracks mobile ifaces from ConnectivityService.
Refactor xt_qtaguid parsing into factory outside of NMS. Add stats
grouping based on UID, and total based on limiting filters like iface
prefix and UID.

We now write battery history directly into a buffer, instead of
creating objects. This allows for more efficient storage; later
it can be even better because we can only write deltas.
The old code is still there temporarily for validation.

We now distribute "wifi started" time across all apps that are
holding WIFI locks that cause it to be started. But only when
WIFI would not normally be running. Also have a mechanism to
distribute other WIFI work that has happened across those processes
based on their use.
Also fixed a bug where we were not retaining the CPU speed step
stats across boots...!

This fixes a problem where applications could ask the location
manager to do very heavy-weight things (like... say... update
location every minute), which would get accounted against the
system instead of the application because ultimately it is the
system making the heavy calls (wake locks, etc).
To solve this, we introduce a new class WorkSource representing
the source of some work. Wake locks and Wifi locks allow you
to set the source to use (but only if you are system code and thus
can get the permission to do so), which is what will be reported
to the battery stats until the actual caller.
For the initial implementation, the location manager keeps track
of all clients requesting periodic updates, and tells its providers
about them as a WorkSource param when setting their min update time.
The network location provider uses this to set the source on the
wake and wifi locks it acquires, when doing work because of the
update period.
This should also be used elsewhere, such as in the GPS provider,
but this is a good start.

- Now track wake locks in battery history.
- Now track sensors in battery history.
- Some filtering of sensory data.
- Fixes to some data that wasn't cleared when resetting battery stats.
- Print amount discharged since last charge.
And the big part -- keep track of wake locks held per process,
and kill processes that hold wake locks too much while they are in
the background. This includes information in the battery stats
about the process being killed, which will be available to the
developer if the app is reported.

We now clear the battery stats when unplugging after the
battery is full. This allows us to use the "total" stats as
a new "since last charged" stat. Total is gone. I never used
it, it was worthless. Since last charged is a lot more
interesting.
The battery history now collects a lot more stats, and keeps
control over how much it can collect. Printing is now more
descriptive.
The kinds of stats have been renamed to SINCE_UNPLUGGED and
SINCE_DISCHARGED. The other two stats are still there, but
no longer printed; a future change will eliminate them
completely along with all of their state.
Change-Id: I4e9fcfcf8c30510092c76a8594f6021e9502fbc1
Modify OOM adj classes a bit, to take into account the new
heavy weight app type, and give "foreground services" their
own category to have a bettery chance to manager them when
things go wrong.
Also add some new code to battery stats to keep a history
of changes to the battery level.
Change-Id: I29f5ab6938777e1a7eafd7d8c38b5e564cc9f96a
Decouples the input dispatch thread from the battery-stats object lock regime,
to avoid the possibility of ever blocking the input dispatch thread on its
behalf. The stats object is widely used and can sometimes be locked for a
very long time (on the order of seconds) during certain extensive dump
operations.
This change does not alter the data format of the battery stats' externalized
representations.
Fixes bug #2530346

Track phone service state changes and use a separate timer for out-of-service
since the hunting can timeout on some devices.
Store the timeout value in the config.xml, as it is device/network specific.
Settings App will also change to use the hunting duration to compute the cost
of zero signal.
More CPU speed stepping happening with newer devices, so we need
to qualify CPU time with the CPU speed, since power consumption
varies greatly by speed. Apps that peg the CPU should get a higher
penaltly.
Also, fix for 2062930: NPE at VolumePreference.onKey()
This adds the PowerProfile class and data file that provides power consumption numbers
for different subsystems. Also added Audio/Video subsystems to track on a per UID basis.
This introduces a new class in the base platform for performing a clean
shutdown (which was copied from the classes in the policies). It
includes new features to send a shutdown broadcast for applications
to do cleanup, and ot have the activity manager pause the current
activity before proceeding with the shutdown. These facilities are
also use to write at the most recent stat files for sync, battery
and user activity.
There are three major classes of changes here:
- Avoid writing lines where their values are often empty, false, or some other typical thing.
- Use partial writes to the PrintWriter to avoid creating temporary strings.
- Use StringBuilder where we need to generate real String objects (and where possible cache the result).
The usage stats service now collects per-activity launch time stats. There are a number of fixes and improvements to its statistics management and collection; it now operates its calendar in GMT and ensures that for checkin purposes it always reports one day and only one complete day to the checkin service.
Also change the checkin option from "-c" to "--checkin" since it is really a special thing.
2 levels as recorded at plug and unplug events. During charge cycles this would be useful because it would tell us
what the start and end levels were in the last discharge cycle. However during a discharge cycle this information could
be misleading as it would give you the level at the last unplug event (beginning the the discharge cycle) and last plug
event (end of the previous discharge cycle).
Now we are still keeping track of 2 values, but they are "discharge cycle start level" and "discharge cycle current level".
During a discharge cycle this will give you the level the current discharge cycle started at, and the current level. During
a charge cycle the same data will be supplied as before (the start/end of the last discharge cycle).

Automated import of CL 144333
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.
