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.

This change is essentially a rewrite of the main input dispatcher loop
with the target identification folded in. Since the input dispatcher now
has all of the window state, it can make better decisions about
when to ANR.
Added a .5 second deadline for processing app switch keys. This behavior
predates Gingerbread but had not previously been ported.
Fixed some timing inaccuracies in the ANR accounting that could cause
applications to ANR sooner than they should have.
Added a mechanism for tracking key and motion events that have been
dispatched to a window so that appropriate cancelation events can be
synthesized when recovering from ANR. This change helps to keep
applications in sync so they don't end up with stuck buttons upon
recovery from ANRs.
Added more comments to describe the tricky parts of PollLoop.

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.

Adds a fire-and-forget save method (startCommit) to the
SharedPreferences.Editor, which is the way most people use it anyway.
This commit adds the implementation. The previous commit added the
interface and docs:

In addition, this change:
-- adds a generic "runPendingWorkFinishers" mechanism to
ActivityThread to wait on async operations that are still
in flight and use it for this.
-- ties runPendingWorkFinishers into Activity.onPause,
BroadcastReceiver, and Service.
-- makes sSharedPreferences keyed on name, not File, to avoid
unnnecessary allocations
-- documents and guarantees what thread
OnSharedPreferenceChangeListener callbacks run on
-- makes a few things in frameworks/base use startCommit(), notably
Preference.java (which was ignoring the return value anyway)

* rename setThreadBlockingPolicy to setThreadPolicy (opens the way to
using StrictMode for non-blocking-related things in the future?)
* add allowThreadDiskWrites() and allowThreadDiskReads() to modify the
current policy mask and return the old one. this will allow turning
off part of StrictMode during certain regions of code. (for
instance, writing to disk in Activity onPause...)

Remove auto-generated AIDL files and replace them with manually edited
.java and .cpp/.h files so that binder calls can be made from either
Java or C++.
Update the makefiles to not attempt to generate the AIDL files and also
remove the old auto-generated .java files.
Put all the storage-related C++ things in libstorage so that we don't
pollute other libraries.

- 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.

This change involves adding a new method to IWindowManager,
monitorInput() that returns an InputChannel to receive a copy of all
input that is dispatched to applications. The caller must have
the READ_INPUT_STATE permission to make this request (similar to
other window manager methods such as getKeycodeState).

The system_server shouldn't touch files on the SD card. This change
moves the things that touch the SD card out to the
DefaultContainerService so that it will get killed if the SD card goes
away instead of the system_server.

We can't use Parcel.writeValue() to write the ParcelFileDescriptor, otherwise
it leaks when returning the value to the caller (the flag gets lost). Change
the way DropBoxManager.Entry gets serialized so that it uses a bit of its own
flags value to track whether the data is a byte[] or a ParcelFileDescriptor.
Modify the dropbox unit test to add extensive checking of Entry serialization
and deserialization under various circumstances, and to include a regression
test to ensure that FD leaking doesn't happen.

Make the initialValue() of the ThreadLocal be null, so checking it doesn't

Now, when Thread A has a strict mode policy in effect and does a
Binder call to Thread B (most likely in another process), the strict
mode policy is passed along, but with the GATHER penalty bit set which
overrides other policies and instead gathers all offending stack
traces to a threadlocal which are then written back in the Parcel's
reply header.

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.
