- Improve wake lock work source updates to also update the current
history tag, in case the new work source gets recorded in the
history.
- Fix bug in recording radio active time that was not distributing
any time to apps.
- No longer hold a wake lock while dispatching data conn active call,
since it comes with its own timestamp.
- Fix issue where the top app was not being cleared while the screen
was off.
- Remove obsolete STATS_LAST stats type.
- Fix bug that was not clearing the total run time when resetting
the stats.

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.

- Add new audio restriction layer to app-ops. Restrictions add
additional constraints to audio operations at a stream-level.
Restrictions do not affect the persistable state, and are purely
additive: that is, they can only impose additional contstraints, not
enable something that has already been disabled. Restrictions
also support a whitelisted set of exempt package names.
- Add new audio stream-level checks to app-ops.
- Implement a provisional OP_PLAY_AUDIO suppression to three
java entry points MediaPlayer, AudioTrack, & SoundPool.
- Enhance vibrator api to take stream information as an optional
hint - the constants correspond to AudioManager stream types.
OP_VIBRATE now supports the stream-level restriction check.
- Simplify Vibrator subclasses by adding default implementations
for two .vibrate calls.
- Migrate NoMan's zen-mode control to use the new app-ops
stream-level restriction mechanism.

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.

Depends on a modification to libsuspend so that we can get
a callback each time the device wakes up, to read the current
wakeup reasons from the kernel. These are then stuffed in
to a new field in the battery history.
Also add new dump options --history-start and --charged
to better control what is dumped.
Finally the alarm manager uses a "*walarm*" tag for history
item wake locks that are coming from a wakeup alarm.

Battery stats used to revolve around a single time base
it maintained, "battery uptime and realtime." This is derived
from the system's uptime and realtime, but only increments while
the device is on battery. It is used to update its timers for
things like the screen being on, wake locks, etc only while the
device is not plugged in to power.
This change formalizes that time base into a separate class that
maintains all of its state. This is used to introduce a new
time base, "battery screen off," which only increments while the
device is on battery *and* the screen is off. Wake locks are now
based on this time base, so we don't count them while the screen
is on -- it is misleading to have them increment while the screen
is on because the device is defined to always stay awake anyway
during that time, so what they are doing is irrelevant.

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.)

We now compute radio active time per application, by distributing
the active time across all applications each time the radio goes
down, weighting it by the number of packets transferred.
Per-app radio power use is now computed using this radio active
time.
This also gives us a new metric "ms per packet", which give an
idea of how effectively an application is using the radio. This
is collected and reported as a new set of stats in the human-
readable checkin. (It can be computed from the raw checkin data).
Also improve sync reporting to include the sync source as used
in wake locks, not just the component name.

* commit '5f652b9fdfbcc279353955f7ef86b72d2ef9f5fb':
open("/dev/rtc0") failure in AlarmManagerService.setTime() should be non-fatal
Move time setting code from SystemClock to AlarmManagerService
* changes:
open("/dev/rtc0") failure in AlarmManagerService.setTime() should be non-fatal
Move time setting code from SystemClock to AlarmManagerService
On devices using /dev/rtc instead of /dev/alarm, updating the
time-of-day clock and RTC are separate syscalls. Hence the clock and
RTC could be left in inconsistent states if two threads called
SystemClock.setCurrentTimeMillis() simultaneously.
By moving this code into AlarmManagerService, we can put a global lock
around AlarmManagerService.setTime() and prevent the race condition.
Note that access to SystemClock.setCurrentTimeMillis() is now gated by
android.permission.SET_TIME, where before it was gated by filesystem
permissions (i.e., could the process write to /dev/alarm or /dev/rtc).
