This change adds a generic Property facility to the SDK, which allows an
easy way to reference fields (private or otherwise) in a general way.
For example, animations can use this facility to animate 'properties'
on target objects in a way that is more code- and compiler-friendly than
the existing String-based approach (for objects which have implemented
Properties, of course). The animator classes have been updated to use
this new approach (in addition to Strings, which are still more generally
useful for objects which have get/set functions but not Property objects).
The change also includes new Property objects on View (which can now be
used in creating animations on Views).
There is an unrelated change on GLES20RecordingCanvas to change the way we
cache bitmaps, which avoids spurious garbage by using an ArrayList instead of
a HashSet.

1. Views are represented as AccessibilityNodeInfos to AccessibilityServices.
2. An accessibility service receives AccessibilityEvents and can ask
for its source and gets an AccessibilityNodeInfo which can be used
to get its parent and children infos and so on.
3. AccessibilityNodeInfo contains some attributes and actions that
can be performed on the source.
4. AccessibilityService can request the system to preform an action
on the source of an AccessibilityNodeInfo.
5. ViewAncestor provides an interaction connection to the
AccessibiltyManagerService and an accessibility service uses
its connection to the latter to interact with screen content.
6. AccessibilityService can interact ONLY with the focused window
and all calls are routed through the AccessibilityManagerService
which imposes security.
7. Hidden APIs on AccessibilityService can find AccessibilityNodeInfos
based on some criteria. These API go through the AccessibilityManagerServcie
for security check.
8. Some actions are hidden and are exposes only to eng builds for UI testing.

The PhoneWindowManager is now responsible for determing this,
since it needs to do this before we can generate the configuration
since we need to take into account the system bar size we will use.
Also the Display should now report the screen height without
including the system bar.

First step of improving app screen size compatibility mode. When
running in compat mode, an application's windows are scaled up on
the screen rather than being small with 1:1 pixels.
Currently we scale the application to fill the entire screen, so
don't use an even pixel scaling. Though this may have some
negative impact on the appearance (it looks okay to me), it has a
big benefit of allowing us to now treat these apps as normal
full-screens apps and do the normal transition animations as you
move in and out and around in them.
This introduces fun stuff in the input system to take care of
modifying pointer coordinates to account for the app window
surface scaling. The input dispatcher is told about the scale
that is being applied to each window and, when there is one,
adjusts pointer events appropriately as they are being sent
to the transport.
Also modified is CompatibilityInfo, which has been greatly
simplified to not be so insane and incomprehendible. It is
now simple -- when constructed it determines if the given app
is compatible with the current screen size and density, and
that is that.
There are new APIs on ActivityManagerService to put applications
that we would traditionally consider compatible with larger screens
in compatibility mode. This is the start of a facility to have
a UI affordance for a user to switch apps in and out of
compatibility.
To test switching of modes, there is a new variation of the "am"
command to do this: am screen-compat [on|off] [package]
This mode switching has the fundamentals of restarting activities
when it is changed, though the state still needs to be persisted
and the overall mode switch cleaned up.
For the few small apps I have tested, things mostly seem to be
working well. I know of one problem with the text selection
handles being drawn at the wrong position because at some point
the window offset is being scaled incorrectly. There are
probably other similar issues around the interaction between
two windows because the different window coordinate spaces are
done in a hacky way instead of being formally integrated into
the window manager layout process.

Wrote initial suite of tests for ThrottleService, checking a variety
of edge cases. Checks going over limits, updating policies, and reset
after cycle elapses.
Moved NTP code in ThrottleService into new TrustedTime interface,
which makes it easier to understand, and allows tests to provide custom
clocks.

Don't hold locks while running create or remove callbacks. That gets a bit
ugly because it means a create could be unwanted by the time it returns.

Dynamically changing a max cache size is clumsy; almost everyone
should set this when they create the cache.
Fix SQLiteDatabase to copy entries into a new cache when the size
is changed. In pratice this will always be immediately after the
SQLiteDatabase is created. Since the cache field is no longer
final, change the guard on the cache field to the SQLiteDatabase
instance itself.

IntentResolver frequently iterates over hundreds of different IntentFilters
and spends much of its time creating iterators and comparing strings.
This change avoids reduces the amount of garbage created by eschewing
iterators where possible. The FastImmutableArraySet type on its own
provides a 2.5x speed boost compared to repeatedly iterating over a HashSet.
In absolute terms, during orientation changes we spent about 160ms resolving
11 intents and performing 1129 calls to IntentFilter.match. Now we spend
half of that time.

...Invalid index 0, size is 0 at

It looks like if an arrow key is dispatched between the time the
list view is told its data set has changed and it does the resulting
layout pass, we could try to move the position to a now invalid
index. This may prevent that from happening.
Also put in a better error message if saving state of a fragment
whose target is no longer in the fragment manager.
And fix a bug in PackageManager where we could return a null from
queryIntentActivities().
And add a new API to find out whether a fragment is being removed,
to help fix issue #3306021: NPE at
android.app.AlertDialog.getDefaultDialogTheme(AlertDialog.java)
Next, for new HC apps we can delay committing data to
storage until the activity is stopped.
Finally, use the new multi-threaded AyncTask executor in a few
places, so we don't have worked blocked by long-running tasks from
the application.

* Define Base64DataException
* Throw it from Base64InputStream & Base64OutputStream
* This enables callers to disambiguate "bad data" from "broken stream",
which makes it more possible to do proper retry logic.
