1. Now when an interrogating client requires an AccessibilibtyNodeInfo
we aggressively prefetch all the predecessors of that node and its
descendants. The number of fetched nodes in one call is limited to
keep the APIs responsive. The prefetched nodes infos are cached in
the client process. The node info cache is invalidated partially or
completely based on the fired accessibility events. For example,
TYPE_WINDOW_STATE_CHANGED event clears the cache while
TYPE_VIEW_FOCUSED removed the focused node from the cache, etc.
Note that the cache is only for the currently active window.
The ViewRootImple also keeps track of only the ids of the node
infos it has sent to each querying process to avoid duplicating
work. Usually only one process will query the screen content
but we support the general case. Also all the caches are
automatically invalidated so not additional bookkeeping is
required. This simple strategy leads to 10X improving the
speed of the querying APIs.
2. The Monkey and UI test automation framework were registering a
raw event listener for accessibility events and hence perform
connection and cache management in similar way to an AccessibilityService.
This is fragile and requires the implementer to know internal framework
stuff. Now the functionality required by the Monkey and the UI automation
is encapsulated in a new UiTestAutomationBridge class. To enable this
was requited some refactoring of AccessibilityService.
3. Removed the *doSomethiong*InActiveWindow methods from the
AccessibilityInteractionClient and the AccessibilityInteractionConnection.
The function of these methods is implemented by the not *InActiveWindow
version while passing appropriate constants.
4. Updated the internal window Querying tests to use the new
UiTestAutomationBridge.
5. If the ViewRootImple was not initialized the querying APIs of
the IAccessibilityInteractionConnection implementation were
returning immediately without calling the callback with null.
This was causing the client side to wait until it times out. Now
the client is notified as soon as the call fails.
6. Added a check to guarantee that Views with AccessibilityNodeProvider
do not have children.

Added a new method ContentObserver.onChange(boolean, Uri) that
receives the changed content Uri. This can help applications make
better decisions about how to interpret a change notification.

Improved the documentation a little bit.
Fixed a bug in ContentService wherein if a ContentObserver was
passed as an argument and its deliverSelfNotifications() method
returned true, then notifyChange would tell all observers that
the change was a self-change even though it was only a self-change
from the perspective of the provided observer.
Deprecated ContentObservable.notifyChange since it is never
used and in general it shouldn't be because we want the notification
to be posted to the handler.

Using a runnable to schedule the action, interrupted by any other
touch event, enabling a catch of a double tap to trigger text selection

This ensures that the SQLite library is always correctly configured
and initialized before other framework or application code has
a chance to use it. This is important because initialization has
to happen at most once so we need to get it right and prevent races.
This change makes it possible to omit the SQLite auto-initialization
workaround from the SQLite library, potentially saving a few cycles
here and there.

Create a LocalLog class for logging within a service for dumping in dumps.
Use it in the NativeDaemonConnector so we can get some insight into what
is happening in these lockups.

When text can indeed be selected, we should always initiate
a text selection on long press. When the WordIterator fails
(for instance if the text is entirely made of punctuation
characters, maybe also with foreign languages), we select
one character.

This error code was introduced at some point to help track when
a database could not be closed because a statement was not finalized.
Now that the DB wrappers have been rewritten, it is technically no longer
poossible for this to happen, so we can remove this.

Bug 5749557
Not clear how we can get an AOOB in that case.
tmp will always have the right length, and indeed the stack
trace attached to that bug shows a correct size of 10.
However, there is an index issue when we build the new
completion array. i is not the correct index to use.
Note however that the original buildDropDown method mentioned
is no longer present in the file. I tried to backtrack, but
the use of arraycopy always seemed correct.

Modified SQLiteConnection and SQLiteSession to support
reentrant execution of SQLite operations, as might occur
when a custom function is invoked by a trigger.
