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.

We weren't logging strictmode violation in the system_server process
in non-user builds (only system apps), even though the rest of the

Also add a missing lock in ActivityManagerService.

The activity manager looks for cases where one app launches immediately
after another. If this happens, a brief toast is shown telling the user
when app is actually running and what was originally starting.

For the duration of the wake lock, 50% of all CPU usage is now
accounted against the app(s) holding partial wake locks, evenly
distributed between them. This is only while the device is on
battery and screen off.

There was a flaw in the service management, when the same activity
is doing a bindService() for the same service IBinder. In this case
the activity would correctly keep a list of all generated connections,
however some other data structures would assume there is only one
connection per IBinder, and thus only remember the last.
When that last connection was unbound, the service would be destroyed
since it thought there were no more connections. Then when the
activity was finished, it would try to destroy the service again and
end up with an ANR because the service was already gone and would
not respond.

It would grant the permission to the temporary ActivityRecord,
not the real one, so it never got cleaned up.
Also allow granting of permissions to services because... well,
it would be really really useful. And it introduces some
refactoring that we'll need to support cut/paste.

- 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.

The NotificationManager tries to crash the calling app, but
in the case of a service calling startForeground, the caller
is the ActivityManager, so system_server goes down.
NotificationManagerService#enqueueNotificationInternal is a
new internal-only method that accepts a UID/PID to use when
punishing bogus notifications (such as the one in
http://b/2869787).

This was originally written as an in-case-we-need-it facility, but was
never actually used in production. It also soaked up a surprising amount
of cpu on occasion, as well as doing sketchy things like demoting the
system_server's primary looper thread to the background cgroup at times.

Introdude a new ActivityStack class that holds all of the

for having multiple activity stacks, though at this point
there should be no change in functionality and the activity

An Activity can declare itself to be "immersive" either by
setting android:immersive="true" in AndroidManifest or by
calling setImmersive(true).
Immersive activities "should" not be interrupted, for
example by Notifications with an associated
fullScreenIntent. (In the future we may even prevent any
non-system application from successfully calling
startActivity() if the foreground activity is immersive.)
Notifications with FLAG_HIGH_PRIORITY set will be shown to
the user in some less-obtrusive way if the frontmost
activity is immersive.

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.

This is a new public API for developers to opt-in to strict rules
about what they're allowed to do on certain threads. (this is the
public face of the @hide dalvik.system.BlockGuard, added recently...)
In practice this will be used for developers to opt-in to declaring
that they don't want to be allowed to do various operations (such as
disk I/O or network operations) on their main UI threads. (these
operations are often accidental, or even when they are fast come with
a good chance of being slow or very slow in some cases....)
Implementation wise, this is just a thread-local integer that has a
bitmask of the things that aren't allowed, and more bits for saying
what the violation penalty is. The penalties, of which multiple can
be chosen, include:
* logging
* dropbox uploading for analysis/reporting
* annoying dialog
* full-on crashing
These are all only very roughly implemented at this point, but all
parts now minimally work end-to-end now, so this is a good checkpoint
commit before this gets too large.
Future CLs will polish all the above 4 penalties, including
checksumming of stacktraces and minimizing penalties for duplicate
violations.

Don't bring up Launcher until after boot complete
The preboot upgrade handling was bringing up the acore process with a default
application object, then the normal "start the HOME app" code was bringing up
Launcher2 [hosted in acore] in anticipation of boot completion... but then it
saw that the host process was alive and continued with Launcher2's init.
Launcher2 depends on a custom application object, however, so it crashed
immediately.
This change ensures that the HOME app is not actually initted at that level
until after boot has completed, at which point its proper application class
can be instantiated.

It looks like there was a subtle bug where Process.setOomAdj() could
return false just because the given process doesn't exist, even though
it is documented to only return false if OOM killing is not supported
at all. This would cause the activity manager to fall into its code
path of trying to clean up processes itself, which it does a much
poorer problem at. I am thinking we may be seeing this problem more
now that the activity manager is killing background processes itself
when there are too many of them.
In addition, this change cleans up and reduces some of the logging
around killing processes.
Finally, try to improve process LRU management a bit by taking
into account process dependencies. Any dependent processes are
pulled up in the LRU list with the processes that is actually
moving. Also, we bring a process up if someone accesses its content
provider.

With the .apk file names now changing during an update, we need
