Added two public methods to Debug. These methods return a String
indicating the caller (getCaller()) or callers (getCallers(int depth))
of the calling method. The String indicates the class, method and line
number of the caller(s). Similar to using Throwable.fillInStackTrace()
but much more concise.

Added a getVibrator() method to InputDevice which returns a Vibrator
associated with that input device. Its uses the same API as the
system vibrator which makes it easy for applications to be modified
to use one or the other.

Moved the core logic of Vibrator into SystemVibrator, potentially
allowing for the creation of other Vibrator subclasses.
Fixed several places where we were creating new Vibrator
instances unnecessarily instead of getting it from the Context.
It is safe to make Vibrator abstract because its constructor
was hidden from the SDK so it was not possible to subclass it.

Packages can be enabled/disabled per user.
This requires maintaining stopped/launched states and
enabled / disabled components and packages per user.
Refactored pm.Settings and PackageSettingsBase to keep
track of states per user.

Changed intent resolution to handle individual user restrictions.
Bunch of IPackageManager calls now have a userId argument.
Make AppWidgetService handle removals of packages.
Added some tests for pm.Settings and PackageManager.

StrictMode posts a message to estimate how long the main thread was

An "UpdateLock" works similarly to a wake lock in API: the caller is
providing a hint to the OS that now is not a good time to interrupt
the user/device in order to do intrusive work like applying OTAs.
This is particularly important for headless or kiosk-like products
where ordinarily the update process will be automatically scheduled
and proceed without user or administrator intervention.
UpdateLocks require that the caller hold the new signatureOrSystem
permission android.permission.UPDATE_LOCK. acquire() and release()
will throw security exceptions if this is not the case.
The "is now convenient?" state is expressed to interested parties
by way of a sticky broadcast sent only to registered listeners. The
broadcast is protected; only the system can send it, so listeners
can trust it to be accurate. The broadcast intent also includes a
timestamp (System.currentTimeMillis()) to help inform listeners that
wish to implement scheduling policies based on when the device became
idle.
The API change here is a tiny one: a dump(PrintWriter) method has been
added to the TokenWatcher class to facilitate getting information out
of it for dumpsys purposes. UpdateLock itself is still @hide.

Instead of acquiring and releasing a barrier using an up/down
counter, we post a message to the queue that represents the
barrier. This is a more natural representation of the barrier
and better matches what we want to do with it: stall messages
behind the barrier in the queue while allowing messages earlier
in the queue to run as usual.
Refactored the MessageQueue a little bit to simplify the quit
logic and to better encapsulate the invariant that all
messages within the queue must have a valid target. Messages
without targets are used to represent barriers.

The synchronization barrier enables selectively blocking
execution of synchronous messages until the barrier is released.
Asynchronous messages may continue running in the meantime.
The barrier is intended to be used to implement more sophisticated
scheduling policies related to view hierarchy traversals. While
traversals are pending, most messages posted to the message queue
must be held up. This is to satisfy the invariant that traversals
will occur before subsequently posted messages are handled.
The exception to this rule are "asynchronous" messages that represent
external events or interrupts that come from other components such
as VSYNC pulses, input events or sensor events. Because these messages
are typically delivered at arbitrary times, they are independent of
traversals or other typical synchronization boundaries.
Messages can now be flagged as asynchronous to indicate that they
are weakly ordered.

Services now must explicitly opt in to being accessed by isolated
processes. Currently only the activity manager and surface flinger
allow this. Activity manager is needed so that we can actually
bring up the process; SurfaceFlinger is needed to be able to get the
display information for creating the Configuration. The SurfaceFlinger
should be safe because the app doesn't have access to the window
manager so can't actually get a surface to do anything with.
The activity manager now protects most of its entry points against
isolated processes.

This reserves a range of uids (for each user) in which these processes
run. These uids are not associated with an application, so they
effectively run with no permissions. When a Service requests to
run in such a process through android:isolatedProcess="true", each
time it is brought up a new isolated process is started with its
own unique uid.
What we have so far gives us the basic infrastructure; more work
remains to further lock down what these uids have access to.
