Added a couple of micro-optimizations to avoid calling wake() unnecessarily
and reduce JNI overhead slightly.
Fixed a minor issue where we were not clearing the "next" field of Messages
returned by the MessageQueue so the Message would hold on to its successor
and potentially prevent the GC from collecting it if the message were leaked
somehow.

This is implemented based on whether we are using the "nosdcard"
product. Needed to tweak aapt to allow use of the product attribute
with other resource definition tags besides strings.

This makes it more future-proof and maintainable, not exposing the
internal bitpacking state.
The implementation is unchanged (the policy is still just an int we pass
around).
Also starts to introduce VmPolicy, for things which are process-wide,
not per-thread. As an initial user, make SQLite's Cursor finalization
leak warnings use StrictMode.

Don't keep tracking OBBs when the volume they're located on goes away.
Remove them from our state tracking maps and then send a notification to
any listener that is still around.
Add a dump handler to MountService so the state of the mount lists
can be inspected.
Change the API to just make a callback directly to the change listener
when mount is called when it's already mounted or unmount called when
it's already unmounted.

Add a callback for users of the StorageManager API to be able to receive
notifications when the requested operation completes for mountObb and
unmountObb.
Add NDK API to get to ObbInfo like the Java API has.
Also update the docs for the API and remove the "STOPSHIP" comments.

Don't kill processes for excessive wake lock use, even if they
are in the background, as long as they have running services.
Also fix some problems with this, such as not noting the kill
in battery stats.
And add killing of processes for cpu usage as well, along with
some optimizations to computing CPU usage.
And fix BatteryWaster to be better behaving for testing these
cases.
Add new "monitor" command to am to watch as the activity manager
does stuff (so we can catch things at the point of ANR).
Finally some miscellaneous debug output for the stuff here, as
well as in progress debugging of an ANR.

Avoids allocating new idle handler arrays on each iteration since
we only need one to copy into.
Coalesced the synchronized blocks.
Hoisted the call to Binder.flushPendingCommands() outside of the
synchronized block.

- New API for iterating over history that will allow a better implementation
in the future.
- Now do writes asynchronously.
Also improve the documentation for Activity.onRetainNonInstanceState().

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.

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...)

- Actually aggregate discharge amounts.
- Actually print the unplugged battery info when currently plugged in.

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.

* Add flags field in OBB footer to support overlays.
* Remove unused 'crypto' and 'filesystem' fields in obbtool (could
later be supported in the "flags" field of the OBB footer).
* Add notes to document OBB classes before shipping.

Add a constant to android.os.Build that returns a device-specific
alphanumeric serial number. It's optional -- it may be blank --
though CTS will require it to be present for non-telephony devices.

- 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.

Merge commit '8c65ee2d509db7dcb50ce4530d52eb5bdca3f917' into gingerbread
* commit '8c65ee2d509db7dcb50ce4530d52eb5bdca3f917':
Add a method to let a properly permissioned app directly
manipulate the user activity timeout. We should come up
with a better API for this, but this is for a last minute
power manager hack to turn off the screen sooner after a
phone call ends.

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.
