network: Adds the functionality to parse uid in netlink messages.
Netlink notifications about the state of the modem contains uid too.
This patch adds the functionality to add that. It also fixes the bug to
parse the timestamp in the message even in cases where the length is
greater than expected.

BatteryStats: Introduce Async external stats requests
Instead of calling out to external processes with a blocking IPC,
pass along a Binder on which the external process can pass back
the response. The calling process can then wait for the reply with
a timeout.
This eliminates watchdog restarts of the system_server when an external
process like telephony or bluetooth hangs.

Initial implementation of light-weight idle mode.
This mode turns on after the screen has been off for 15 minutes,
and then cycles through 15 minutes of idle and 1 minute of
maintenance, ragardless of whether the device is moving around.
It currently only impacts network access and sync/job scheduling.
It does not remove access to wake locks or alarms for any apps.
It also doesn't report in the public API that the device is in
idle mode (since it isn't modifying the behavior of the power
manager) -- this is probably what we desire, since we don't want
stuff like GCM to be reporting these frequent changes.
We'll probably at least want to have the alarm manager do some
kind of more aggressive batching of alarms in this most (not allowing
more than one wakeup every minute?). That's for the future.
Also updated batterystats to include this new information, which
means the format of some of the data has changed -- device_idle
is no longer a flag, but an enum of (off, light, full), and there
is no information about time spent in light modes.
Also added new data about the maximum duration spent in both light
and full idle modes, to get a better understanding of how those
are behaving.
And did a little cleanup of DeviceIdleController, removing the
sensing alarm which was redundant with the regular alarm.

Improve tracking of screen on reasons.
- New screen on app op to record the last time each app has
caused the screen to be turned on.
- New battery stats event that tells us the reason the screen
has been asked to turn on.
- Propagate out power manager API to specify the reason a caller
is asking to have the screen turned on.
Note that currently the window flag to turn the screen on bypasses
much of this because it is being handled in the window manager by
just directly telling the power manager to turn the screen on. To
make this better we need a new API where it can specify who it is
calling the API for.

More work on device idle mode and other power stuff.
Add idle mode support to the alarm manager. Introduce
a new concept of flags associated with alarms to tell
the alarm manager how to treat the alarm -- they allow
everything from the alarm that will bring us out of idle
mode, to alarms that are allowed when idle or should
also bring us out of idle. The standalone boolean is
now also a flag.
(Note there is currently no protection from user space
setting the flags however it wants; I will be working
on that in a follow-up change.)
When in idle mode, the alarm manager pushes all alarms
that shouldn't execute during that time over to a
separate list that is not executed until out of idle.
To help with this, I reworked a bit how Alarm objects
are managed, so that when rebatching or moving between
lists we don't have to allocated new objects but can
just use the same existing instance.
Also tweaked the sync manager to deal with idle mode,
which currently just means doing the same thing as when
low on storage -- turning off sync.
Add new ACTION_CHARGING and ACTION_DISCHARGING broadcasts
that apps can listen for to know when the device is actively
charging and discharging. These are better than the old
POWER_CONNECTED and POWER_DISCONNECTED ones because we only
report charging when we actually see that there is enough
power being provided to charge the battery (and will report
discharging if there is not enough power).
The job controller uses these new actions for scheduling
jobs that want to run while plugged in. Removed the
"stable charging" stuff while doing so, since the new
charging state serves as an even better signal for that.
Introduced two new process states: FOREGROUND_SERVICE and
TOP_SLEEPING. This will allow us to treat foreground services
specially (such as still allowing network access to them for
background music playback) while not mixing them together with
whatever happens to be the top activity while the device is
asleep.
Also some other small cleanup here and there.

First stab at device idle mode.
Introduce a new device idle controller service that
monitor's the device state and determines when to go
in to idle mode. When in idle mode, all we do right
now is turn off network access the same as we do for
power save mode. Many more things should come in the
future -- stopping the alarm manager from scheduling
(most) alarms, telling GmsCore for it to stop doing
stuff, etc.
Battery stats now has state tracking for devie idle
mode, as well as events for the reasons we can come
out of idle mode (significant motion or the device
becoming active). Also added new events noting when
packages are installed.
Renamed the "low power" event in battery stats to
"power save" because the former was just way too
confusing.
Finally, fix buffer size reading kernel wake locks.
(Stupidly, just increasing the buffer size. Ideally
we should try to be smarter and grow our buffer to
fit the data available, but I'll leave that for
another time.)

But wait, there's more!
- Keep track of sync durations in the aggregated stats.
- Add events for users that are running and in the foreground.
- Rework the activity manager's tracking of stuff using
battery in the background to be based on proc stats, which
allows it to be better about determing when it should reset
its tracking of background work.
- Also add tracking of scheduled job execution, like we are
doing for syncs.
- And once I started hooking battery stats in to
JobSchedulerService, I found a few things I couldn't stop myself
from changing: (1) make it very explicit that it doesn't start
scheduling jobs until we have reached the point in system boot
where third party apps are allowed to run, and (2) adjust
the various for loops to not use iterators.

Also modify history dump so that when we hit a RESET or START
command, we clear our previous history data, so the next event
will include new data. This means if you are scanning through
the output, you must at this point clear any binary stats you
have like "running" or "wake_lock" or else you will continue to
think they are on until whatever point later they get turned on
and then back off.

Battery stats: track actually running time
Use the uptime while creating the battery stats history to
generate a new event indicating when the CPU is actually running.
We can do this in combination with the new event reporting when
the CPU comes awake, looking at the difference between the
uptime and elapsed time at that point to determine when it last
when to sleep.
Also use this information to generate a new set of aggregated
states, the uptime caused by each wake reason.
Finally use new radio down timestamp to adjust the times we
compute for radio use. Note that this information is not (yet)
being used to adjust how these are recorded in the history.

Reduce wake lock noise in battery history.
When the work source of a wake lock was changed, this would
cause the old wake lock to be released in battery stats before
the new one was acquired (the power manager would correctly
keep holding the associated wake lock). This resulted in a
pointless entry in the battery history showing the last wake
lock being released and a new one acquired.
This change adds a new path in to battery stats to report
when a wake lock has changed, allowing it to acquire the
new wake locks first before the old ones, so it can't drop
down to zero wake locks. This also provides better timing
information, as the same current time can be used for both
operations.
In addition, added a new kind of history entry for the
current time, so you can tell when in actual world clock
time the battery data is happening.

Hold a wake lock while dispatching network activity events.
Also add new API for determining whether the current data network
is active, and thus better scheduling network operations. This
API is designed to not be tied to a mobile network -- regardless
of the network, apps can use it to determine whether they should
initiate activity or wait. On non-mobile networks, it simply always
reports as the network being active.
This changed involved reworking how the idle timers are done so
that we only register an idle timer with the current default
network. This way, we can know whether we currently expect to
get callbacks about the network being active, or should just always
report that it is active. (Ultimately we need to be getting this
radio active data from the radio itself.)

Start tracking radio up time.
We now always turn on network state tracking for mobile,
and push this information down to battery stats.
In battery stats we use this to both log the changes in
the history and keep track of the total time the mobile
radio was active.
Power computation is switched over to using this information
to help determine power use, which will hopefully make it
more accurate (not counting inaccuracies in knowing when it
actually goes down).
Note yet done is aggregating this data per-uid, to better
emphasize which apps are causing the radio to be up. Right
now we just spread the total time across all uids weighted
by the total number of packets they have sent and received.
Also put in the battery stats infrastructure for bluetooth to
address issue #12973036: Improve power_profile.xml

Improve logging of first wake lock, history size.
We now try to have a better label for the first wake lock
that is acquired in the log. This is done in two ways:
- The alarm manager now sorts the alarms it is going to
execute so that wakeup alarms are first, which are more
important w.r.t. which one should be logged.
- There is a new power manager facility to make a wake lock
as "unimportant for logging," which just means in battery
stats that a wake lock acquired after that can be considered
the actual one to log. This is only used by the alarm manager
to mark its TIME_TICK alarms as unimportant for logging.
Also reworked the battery history code to be cleaner and a bit
smaller. There is no longer a separate EVENT command, instead
the event code and tag are just another thing that can be included
in an UPDATE command.
The bits used in the first history int are also re-arrange, so
that only the ones that really change a fair amount in the state
bits are up at the top and there is no longer space used for
the command code (since now it is always just UPDATE). This
allows us to have more room for the time delta at the bottom,
to better avoid situations where we need to write an int delta.

Battery stats improvements.
- Adjust total power use when there is unaccounted power so that our
percentages don't end up > 100%.
- Fix accounting of isolated uids to be against the owning real app
uids.
- Rework how we put cpu use into the battery stats to no longer need
this uid name cache that can confuse the uid it is associated with.
- Finish implementing events in the history, adding a string pool and
reading/writing/dumping them.
- Add first two events: processes starting and finishing.
- Fix alarm manager reporting of wakeup alarms to be adjusted by the
WorkSource associated with the alarm, so they are blamed on the
correct app.
- New "--history" dump option allows you to perform a checkin of
only the history data.
- Fixed BitDescription bug that would cause incorrect printing of
changes in some states.

Accumulate network statistics based on deltas.
Network stats are now read out of the kernel in one sweep, instead of
reading per-UID. We now accumulate the delta traffic between each
stats snapshot using the well-tested SamplingCounter pattern.
Since Wi-Fi and mobile traffic have different costs, track each
separately. Avoids counting misc interfaces like loopback and
ethernet under total.

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!

Include WIFI scan's in Battery Stats.
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.

Improve power tracking of WIFI use.
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...!

Track client requests through location manager.
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.

Various battery info things:
- 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.

Various improvements to battery stats collection
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.

AI 144333: Change the way the battery level tracking code works in BatteryStats. Before we simply kept track of the last
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).
