1. The function for finding where the accessibility focus in a virtual
node tree presented by an AccessibilityNodeProvider is not needed
API since the framework already keeps track of the accessibility
focused virtual node in order to draw the focus rectangle. This API
adds unnecessary complexity to developers of AccessibilityNodeProviders.

Improve the API around ActionProvider visibility overriding. Allow the
application to notify whatever is hosting the ActionProvider that
visibility has changed in a way that is friendly to alternate support
library-style reimplementations of MenuItem.
Allow MediaRouter.Callback implementations to add or remove themselves
or other Callbacks during dispatch of callback events.
Make MediaRouteActionProvider track the visibility of corresponding
menu items more accurately.

* Add ActionProvider#overridesItemVisibility and isVisible.
These methods allow an ActionProvider to override the
visibility of a MenuItem that it is bound to. If a MenuItem
has been explicitly hidden by the application, it will not
be visible.
* Change MediaRouteActionProvider to not require a MediaRouter
callback, to avoid extra lifecycle management headaches.

1. Currently we are providing accessibility focus search algorithm in the
framework and we are also setting accessibility focus from hover. It
appears that implementing a focus search strategy that works for all
accessibility services is non trivial task if feasible. Based on
feedback from the developers of two such services at Google - TalkBack
and BarilleBack - the built in focus search does not quite match what
they need and they would like to implement a custom strategy.
Hence, having APIs for accessibility focus search in the framework does
not make. Therefore, we are hiding this APIs and later will take out the focus
search logic and allow the accessibility service to implement search.
Also putting accessibility focus from hover is tightly integrated with
the focus search since the set of views that get accessibility focus
from hover should be the same as the set of views returned by the
focus search routine. Therefore, we are letting the accessibility service
decide where to put accessibility focus when it gets an accessibility
hover event.

This reverts commit 858491ba13
It turns out that Surface Flinger is supposed to generate fake vsyncs while the screen is off, but sometimes it wasn't working due to a bug. That bug has now been fixed by the following change: I7c6abc23bb021d1dfc94f101bd3ce18e3a81a73e
When the screen is off, we might not receive real vsync pulses from
the hardware which would cause posted Choreographer callbacks to not run.
This is bad because messages in the Looper might be blocked behind a barrier
that is scheduled to be removed by one of those Choreographer callback
(see ViewRootImpl.doTraversals). Until the barrier is removed, those messages
will not run. To prevent starvation of the Looper, we synthesize fake vsync
pulses at a reduced rate whenever the display hardware stops generating them.
This change should fix a variety of rare non-deterministic bugs where
the system might appear to be unresponsive while the screen is off,
and spurious ANRs reported shortly after the screen is turned back on.

Timeout after 2.5 seconds.
Because communication with an IME occurs asynchronously
using oneway binder calls, it's possible for an input event
that was delegated to the IME to be dropped on the floor.
When this happens, the app (not the IME!) will get blamed
for the problem and will ANR forever.
Even if an event is not dropped on the floor, we should
eventually time out event dispatch to the IME if it's
being too slow.
This patch implements a timeout on all events delegated
to the IME. When the timeout expires, the event is marked
as having not been handled by the IME and the application
gets a crack at it. We also write a message to the log when
this occurs.
Ensure that we do not invoke the event finished callback
while holding the InputMethodManager's lock to avoid
potential deadlocks.
Fixed a minor bug where the InputMethodManager would not
remember the id of the current input method. This caused
the log messages and dumpsys state to print "null" as the
current input method id.

Bug #6642475
When expanding the status bar, create one layer per notification instead of
a single giant layer for the pile of notifications. This prevents layer
creation failure when the total height of the notifications is larger
than the maximum allowed texture size in OpenGL ES 2.0.
This change only enables layers on notifications that will be visible
once the notification area is fully expanded.

...MediaPlayer.setScreenOnWhilePlaying seem broken
We need to correctly clear the keep screen on flag when the view
hierarchy request is gone... and to do that, we need to keep the
actual state of the flag requested by the app. Also when the app
changes its state, we need to compute the proper value based on
both the app request and any requests in the view hierarchy.

When an ANR occurs, log the associated reason.
When an event takes too long to process (currently more than 2 seconds)
log basic information about the event including how long it actually
took.
Dump the contents of the inbound, outbound and wait queues as part

Detect wonky vsync timestamps (should they occur) and
warn loudly about them.
Warn when too many frames are skipped. The threshold is pretty
conservative right now (only warn if at least 30 frames are skipped)
but it can be adjusted using system property. Even skipping just a
couple of frames is enough to generate noticeable jank.
The threshold is currently intended to help track down bigger problems
such when an app does too much work on the UI thread.

Bug #6596807
A crash would occur in the following situation:
- WebView registers a functor with the hardware renderer
- The hardware renderer gets disabled
- WebView attemps to unregister its functor
Unregistering the functor fails because the hardware renderer is now disabled.
When the renderer becomes enabled again, the functor is invoked, which leads
to a native crash.
This change simply allows functors to always be unregistered, even when the
renderer is disabled. A disabled renderer only means that it will not be used
for rendering; as such, unregistering a functor is a valid operation and
should be allowed.

1. The character and word iterators were use the application
context to keep track of locale changes. However, for widgets
the context from which the app context is obtained is custom
created therefore the app context is null and the iterators
code does not expect that. Now we are caching the locale
and update it when the configuration changes.
