...content provider and updating its oom adj
This introduces the concept of an "unstable" reference on a content
provider. When holding such a reference (and no normal stable ref),
the content provider dying will not cause the client process to be
killed.
This is used in ContentResolver.query(), .openAssetFileDescriptor(),
and .openTypedAssetFileDescriptor() to first access the provider
with an unstable reference, and if at the point of calling into the
provider we find it is dead then acquiring a new stable reference
and doing the operation again. Thus if the provider process dies
at any point until we get the result back, our own process will not
be killed and we can safely retry the operation.
Arguably there is still the potential for a race -- if somehow the
provider is killed way late by the OOM killer after the query or
open has returned -- but this should now be *extremely* unlikely.
We also continue to have the issue with the other calls, but these
are much less critical, and the same model can't be used there (we
wouldn't want to execute two insert operations for example).
The implementation of this required some significant changes to the
underlying plumbing of content providers, now keeping track of the
two different reference counts, and managing them appropriately. To
facilitate this, the activity manager now has a formal connection
object for a client reference on a content provider, which hands to
the application when opening the provider.
These changes have allowed a lot of the code to be cleaned up and
subtle issues closed. For example, when a process is crashing, we
now have a much better idea of the state of content provider clients
(olding a stable ref, unstable ref, or waiting for it to launch), so
that we can correctly handle each of these.
The client side code is also a fair amount cleaner, though in the
future there is more than should be done. In particular, the two
ProviderClientRecord and ProviderRefCount classes should be combined
into one, part of which is exposed to the ContentResolver internal
API as a reference on a content provider with methods for updating
reference counts and such. Some day we'll do that.

The window manager now performs the crop internally, evaluating
it every animation from, to be able to update it along with
the surface position.

- Fading out recents first, then scaling up app
thumbnail
- Fade Recents out over 130ms
- Delay the window animation for 200ms first,
then animate for 200ms (previously we didn't delay
and then animated for 300ms)

This will be used to determine which parts of a window a completely
hidden by system UI elements (status bar, nav bar, system bar) so
that they can be clipped out from rendering.

On some hardware allocating a new graphics buffer is quite
expensive, which blocks updates to the UI. This can cause
glitches when performing window animations.
To reduce these glitches, the view hierarchy will now only
allow itself to be drawn once if its window is being shown
while the window manager is animating, not resuming draws
until it is told that the animation is done.

Simplified input injection API down to just one call.
Removed all input state reading API. It was only used by the
window manager policy and required a permission that applications
could not obtain. READ_INPUT_STATE is now unused and deprecated.

The status bar and navigation bar are two completely separate
elements, with their own semantics. The system bar now classifies
itself as a navigation bar, since that is really how it behaves.
This required rewriting the HDMI resizing code, so that it is
all done by PhoneWindowManager since that is what is responsible
for the size of the navigation bar (and thus now system bar). This
actually gets rid of a fair amount of code, and means we can also
do the same thing for a pure navigation bar.
Likewise the system bar now has the navigation bar ability to be
hidden when requested by system UI flags. To get the behavior
we want on Xoom, we only allow the nav bar to be hidden when it
will help provide a better aspect ratio for showing widescreen
videos.
Finally the nav/system bar now animates when hidden and shown.

- Added a new custom PNG chunk that carries the layout padding ints.
- Extract the padding ticks from .9.png images and store in the chunk.
- Load the padding information at runtime into Bitmap and NinePatchDrawable.
- The new chunk is ordered first so that it doesn't cause a problem in older
versions of the platform.

Not perfect yet by far, but something.

Since JB, com.android.internal.R does not contain all the resources,
instead only the ones that are accessed through Java.
This means we need to dynamically generate IDs for resources that are
private and only accessed from other XML resources. This is done
through the DynamicIdMap class.
Also add a PolicyManager and a PowerManager since those are now
needed by ViewRootImpl?!?

This will be used to allow new features to be requested... such as,
say, a special kind of animation. Right now there are no options
defined.

XmlPullAttribute can query for attributes and return them in a given

This change makes it much easier to make sense of the messages that
get posted to the ViewRootImpl's handler by encapsulating their point
of dispatch within the ViewRootImpl itself.
As part of this change, the View.AttachInfo now carries a reference
to the ViewRootImpl itself, which simplifies some code that used
to try to find the ViewRootImpl by getting the root view's parent.
In principle, it might have been nice to hide the ViewRootImpl from
the View hierarchy but in practice the two were coupled in many ways.

Instead of using a simple ImageView for the icon, this uses the platform
layout/action_bar_home which uses a custom class to position and resize
the icon (and also supports the Up icon that we don't yet support).
This ensures that the icon is properly positionned and sized like
on devices.

Added new API to enable cancelation of SQLite and content provider
queries by means of a CancelationSignal object. The application
creates a CancelationSignal object and passes it as an argument
to the query. The cancelation signal can then be used to cancel
the query while it is executing.
If the cancelation signal is raised before the query is executed,
then it is immediately terminated.
