Fixing memory leaks in the accessiiblity layer.
1. AccessibilityInteractionConnections were removed from the
AccessiiblityManagerService but their DeathRecipents were
not unregistered, thus every removed interaction connection
was essentially leaking. Such connection is registered in
the system for every ViewRootImpl when accessiiblity is
enabled and inregistered when disabled.
2. Every AccessibilityEvent and AccessiilbityEventInfo obtained
from a widnow content querying accessibility service had a
handle to a binder proxy over which to make queries. Hoewever,
holding a proxy to a remote binder prevents the latter from
being garbage collected. Therefore, now the events and infos
have a connection id insteand and the hindden singleton
AccessiiblityInteaction client via which queries are made
has a registry with the connections. This class looks up
the connection given its id before making an IPC. Now the
connection is stored in one place and when an accessibility
service is disconnected the system sets the connection to
null so the binder object in the system process can be GCed.
Note that before this change a bad implemented accessibility
service could cache events or infos causing a leak in the
system process. This should never happen.
3. SparseArray was not clearing the reference to the last moved
element while garbage collecting thus causing a leak.

Fixing errors in position information of scrollable views reported for accessibility.
1. ScrollView/HorizontalScroll view were reporting only the scroll X and Y but
failed to convey the max scroll along X and Y so the position can be determined.
2. WebView was not reporting correctly its scroll position for accessibility.
3. Some descendants of AdapterView were reporting incorrect position information.
4. Updated the accessibility docs with some details about the scroll information.
5. Cleaned up duplicated code.

The logic for not populating text to some accessibility events is scattered.
1. Some accessibility evenents should not and were not dispatched for
text population but there was no centralized location for enforcing
this - rather the system was firing them in a specific way or there
were conditions in a few places enforcing that. Now this is centralized
and clean.
2. Updated the documentation with some new event types the were lacking.
3. Explicitly stated in the documentaition which events are dispatched to
the sub-tree of the source for text populatation.

Touch exploration separate setting and API to poll the latter state.
1. Seperated touch exploration to be a seperate setting rather being
magically enabled by the system of accessiiblity is on the there
is at leas one accessibility service that speaks enabled. Now
there is a setting for requesting touch exploration but still the
system will enabled it only if that makes sense i.e. accessibility
is on and one accessibility service that speaks is enabled.
2. Added public API for checking of touch exploration is enabled.
3. Added description attribute in accessibility service declaration
which will be shown to the user before enabling the service.
4. Added API for quick cloning of AccessibilityNodeInfo.
5. Added clone functionality to SparseArray, SparseIntArray, and
SparseBooleanArray.

Added scroll and text selection change accessibility events.
1. Added scrolling accessibility event to provicde feedback
when a view is scrolled.
Note: We need scroll events for ICS since even though we have
touch exploration the user does not know when something
is scrollable and not feedback is provided while scrolling.
bug:4902097
2. Added a text selection change event to provide feedback
for selection changes including cursor movement.
Note: We need the text selection change events for ICS since
even though the IME supports navigation in text fields
the user receives no feedback for the current selection/
cursor position.
bug:4586186
3. Added a scrollable property to both AccessibilityEvent and
AccessibilityNodeInfo. The info has to describe the source
in terms of all properties that make sense for accessibility
purposes and the event has this property (kinda duplicated)
since clients will aways want to know if the source is
scrollable to provided clue to the user and we want to avoid
pulling the info of the source for every accessibility event.

Final polish of the interrogation feature.
1. Added a new event type for notifying client accessibilitiy
services for changes in the layout. The event is fired at
most once for a given time frame and is delivered to clients
only if it originates from the window that can be interrogated.
2. Exposed the findByText functionality in AccessibilityNodeInfo.
This is very useful for an accessibility service since it allows
searching for something the user knows is on the screen thus
avoiding touch exploring the content. Touch exploring is
excellent for learning the apps but knowing them search is
much faster.
3. Fixed a bug causing an accessibiliby service not to receive
the event source in case of more than one service is registered
and one of them does not have paermission to interrogate the window.
The same event was dispatched to multiple services but if one
of them does not have interrogation permission the event is
modified to remove the source causing subsequent serivices not
to get the later.
4. Moved the getSource setSource methods to AccessibilityRecord
instead in AccessibilityEvent.
5. Hiden some protected members in AccessibilityRecod which should
not be made public since getters exist.
6. Added the View absolute coordinates in the screen to AccessibilityNodeInfo.
This is needed for fast computation of relative positions of
views from accessibility - common use case for the later.
7. Fixed a couple of marshalling bugs.
8. Added a test for the object contract of AccessibilityNodeInfo.

Interrogation of the view hierarchy from an AccessibilityService.
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.

Accessibility serviceconfiguration via meta-data
Note: This is a part of two CL change and contains the
system changes without updates to the settings.
1. Added a mechanism for configuring an accessibility service via
XML file specified in a meta-data tag (similar to IMEs).
2. Added property for specifying a settings activity for an
accessibility service.
3. Refactored the APIs in AccessibilityManager to return
lists of AccessiblityServiceInfo instead ServiceInfo
since the former describes an AccessibilityService in
particular (similar to IMEs).

Touch exploration feature, event bubling, refactor
1. Added an Input Filter that interprets the touch screen motion
events to perfrom accessibility exploration. One finger explores.
Tapping within a given time and distance slop on the last exlopred
location does click and long press, respectively. Two fingers close
and in the same diretion drag. Multiple finglers or two fingers in
different directions or two fingers too far away are delegated to
the view hierarchy. Non moving fingers "accidentally grabbed the
device for the scrren" are ignored.
2. Added accessibility events for hover enter, hover exit, touch
exoloration gesture start, and end. Accessibility hover events
are fired by the hover pipeline. An accessibility event is
dispatched up the view tree and the topmost view fires it.
Thus predecessors can augment the fired event. An accessibility
event has several records and a predecessor can optionally
modify, delete, and add such to the event.
3. Added onPopulateAccessibilityEvent and refactored the existing
accessibility code to use it.
4. Added API for querying the currently enabled accessibility services
by feedback type.

Text in accessibility events not consistent
bug:2513822
Text added to accessibility events is truncated to max
length. However, the fromIndex and toIndex properties
are relative to the text before being truncated, thus
potentially our of bound. Removed the max length
limitation because test very rarely is longer that
500 characters and in the cases in which text is longer
than 500 character it will not be a real problem to
pass a bit more data through an IPC (very rarely).
