This change adds several traits and properties to AccessibilityNodeInfo
aiming to allow better description of native Android components to
accessibility services as well as mapping web content to native Android
node info tree.

This change adds simple APIs that enable an Android application
to generate a PDF document by drawing content on a canvas.

isAttachedToWindow does what it says on the label and provides a
standard, public API for checking a view's attachment state. This
removes the need for tracking this out of band in response to
onAttachedToWindow/onDetachedFromWindow in custom view
implementations.
hasLayout returns true whenever the view has been through at least one
call to layout() since the last time it was attached to or detached
from a window. This allows for standard checks in code that needs to
behave differently if first layout has not completed yet, such as
whether or not to no-op an animation in order to set up initial state.

Add TransitionManager.beginDelayedTransition() to handle starting a transition
on the next frame for a given scene root based on all changes that
take place between the first call to that method and the next animation frame.
Issue #9321937 Transitions: consider batching up multiple scene actions

- New core API classes in android.hardware.photography
- android.media.Image and android.media.ImageReader classes for
application access to direct hardware image buffers.
- Additions to android.graphics.ImageFormat to describe new image
types needed by new camera API.
- Some documentation included; very little implementation.

Small fixes in CrossFade to handle more general situations.
Also, added API to CrossFade to enable different behaviors during
the transition.

Moves from exposing the internal structure of a drawable state list
to only exposing the data. Adds getCapacity() and mutate() as
package-private APIs to support various drawable subclasses.

1. Before we were firing an accessibility event from the common
predecessor of views with accessibility related state changes
every X amount of time. These events designate that the tree
rooted at the source is invalid and should not be cached.
However, some of the state changes do not affect the view tree
structure and we can just refresh the node instead of evicting
and recaching nodes infos for views that did not change. Hence,
we need a way to distinguish between a subtree changed over a
node changed.
Adding a new event type will not work since if say two siblings
have local changes and their predecessor fires a window state
change event, the client will drop the subtree rooted at the
parent including the two views with changes. Subsequent, more
specialized events emitted from the two changed siblings will
be useless since the parent which did not changed is already
evicted from the cache. Conversely, if the specialized events
are fired from the two siblings with local changes and they
are refreshed in the cache the subsequent window state change
event from the common predecessor will force the refreshed
nodes to be evicted.
Hence, to enable distinction between node being changed and
a subtree baing changed while not changing existing behavior,
we will fire only window content change event with an additional
argument specifying what changed - node or a subtree for now.
Also if the changes are local to a view we fire the window
content changed event from the view. So, the two siblings will
fire such an event independently and the client will know that
these are local changes and can just refresh the node. If the
changes are structural, then we fire the window state change
event from the common predecessor.
2. Added the input type of a text view as one of the properties
reported by an AccessibilityNodeInfo. It is nice to prompt the
user what input is expected.
3. Added a bundle for optional information to AccessiiblityNodeInfo.
For example, it will be used for putting web specific properties
that do not map cleanly to Android specific ones in WebView.
4. AccessibilityInteractionController was not taking into account
whether the current accessibility focused node is shown before
returing it. Hence, a disconnected node would be returned and
caching it puts our cahche in an inconsistent state.

Added new field (+setter and getter) to SynthesisRequest with
Uid of a calling process. TTS service will be able to discover
packages names associated with caller using
PackageManager.getPackagesForUid.
This will allow to block buggy or poorly designed programs from
an unintentional DDoS attacks against TTS service.

The new ArrayMap class is more efficient for small collections.
Transitions use maps all over the place to collect/use property
values in setting up the transition animations. Changing to ArrayMap
should be more efficient, especially in terms of memory allocations
and GCs.

Remove some abstraction-breaking magic in ActionBarView and replace it
with proper resolution of the icon/logo when creating a window. The
old implementation relied on the ActionBarView's context being an
Activity.
