1. This change converts the accessibility manager service to
maintain a state per user. When the user changes the services
for the user that is going away are disconnected, the local
accessibility managers in the processes for this user are
disabled, the state is swapped with the new user's one, and
the new user state is refreshed.
This change updates all calls into the system to use their
user specific versions when applicable. For example, regisetring
content observers, package monitors, calls into other system
services, etc.
There are some components that are shared across users such
as UI created by the system process and the SystemUI package.
Such components are managed as a global state shared across
all users and are updated accordingly on a user switch. Since
the SystemUI is running in a normal app process this change
adds hidden APIs on the local window manager to allow the
SystemUI to notify the accessibility layer that it will run
accross users.
Calls to AccessibiltyManager's isEnabled(), isTouchExplorationEnabled()
and sendAccessibilityEvent return false or a are a nop for a
background user sice he should not send accessibility events,
and should not perform touch exploration.
Update the internal accessibility tests due to changes in the
AccessibilityManager.
This change also fixes several issues that were encountered
such as calling out the accessibility manager service with a
lock held.
Removed some incorrect debugging code from the TouchExplorer
that was leading to a system crash.

Split WindowManagerImpl into two parts, the WindowManager
interface implementation remains where it is but the global
communications with the window manager are now handled by
the WindowManagerGlobal class. This change greatly simplifies
the challenge of having separate WindowManager instances
for each Context.
Removed WindowManagerImpl.getDefault(). This represents the
bulk of this change. Most of the usages of this method were
either to perform global functions (now handled by WindowManagerGlobal)
or to obtain the default display (now handled by DisplayManager).
Explicitly associate each new window with a display and make
the Display object available to the View hierarchy.
Add stubs for some new display manager API features.
Start to split apart the concepts of display id and layer stack.
since they operate at different layers of abstraction.
While it's true that each logical display uniquely corresponds to a
surface flinger layer stack, it is not necessarily the case that
they must use the same ids. Added Display.getLayerStack()
and started using it in places where it was relatively easy to do.

Introduce IRingtonePlayer, which handles playback for both Ringtone
objects and Notifications. SystemUI now hosts this player, which it
registers with AudioService. It also keeps MediaPlayer instances
warm, and cleans them up after stop() or Binder death.
Move both Ringtone and NotificationManagerService to play back audio
through this new interface.

The status bar and navigation bar are two completely separate
elements, with their own semantics. The system bar now classifies
itself as a navigation bar, since that is really how it behaves.
This required rewriting the HDMI resizing code, so that it is
all done by PhoneWindowManager since that is what is responsible
for the size of the navigation bar (and thus now system bar). This
actually gets rid of a fair amount of code, and means we can also
do the same thing for a pure navigation bar.
Likewise the system bar now has the navigation bar ability to be
hidden when requested by system UI flags. To get the behavior
we want on Xoom, we only allow the nav bar to be hidden when it
will help provide a better aspect ratio for showing widescreen
videos.
Finally the nav/system bar now animates when hidden and shown.

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.

There is now one SystemUIService, which starts the status bar service.
Pretty soon there will be other things running in here too. This way
we don't need to have each of them started by something individually.
This also moves the choice between tablet and phone status bar into
SystemUI.apk, which seems like a much better place for it.
