Added more complete support for logical displays with
support for mirroring, rotation and scaling.
Improved the overlay display adapter's touch interactions.
A big change here is that the display manager no longer relies
on a single-threaded model to maintain its synchronization
invariants. Unfortunately we had to change this so as to play
nice with the fact that the window manager wants to own
the surface flinger transaction around display and surface
manipulations. As a result, the display manager has to be able
to update displays from the context of any thread.
It would be nice to make this process more cooperative.
There are already several components competing to perform
surface flinger transactions including the window manager,
display manager, electron beam, overlay display window,
and mouse pointer. They are not manipulating the same surfaces
but they can collide with one another when they make global
changes to the displays.

This patch introduces the ability to create a Context that
is bound to a Display. The context gets its configuration and
metrics from that display and is able to provide a WindowManager
that is bound to the display.
To make it easier to use, we also add a new kind of Dialog
called a Presentation. Presentation takes care of setting
up the context as needed and watches for significant changes
in the display configuration. If the display is removed,
then the presentation simply dismisses itself.

Calling detachViewFromParent() without calling remove or attach in the
same drawing frame could, in some situations, cause a crash in the native
DisplayList code. detach/attach are intended to be very lightweight and do
not manage the native DisplayList content the same way that add/remove do.
Nor do they cause an invalidate() or requestLayout(), which would cause the
native structures to get recreated appropriately.
This fix makes this process more robust in two ways:
- DisplayLists should not get finalized (therefore destroying their native
structures) when there are still parent DisplayLists referring to them
(each DisplayList keeps references to its child DisplayLists). This will
prevent the native crash associated with unmatched detach*() calls.
- The docs for detach/attach have been enhanced to make it easier for
developers to understand how to use these methods more correctly and
successfully.

The Drive application was calling PopupWindow.dismiss from within
onMeasure. This caused dispatchDetachedFromWindow to be called
from within performTraversals. Since dispatchDetachedFromWindow
destroys much of what performTraversals uses this was a disaster
waiting to happen.
This fix adds a check for seeing if die(immediate=true) is being
called from within performTraversals. If it is then die doesn't
execute doDie immediately, but instead treats it as a call to
die(immediate=false).
Fixes bug 6836841.

Split the DisplayManager into two parts. One part is bound
to a Context and takes care of Display compatibility and
caching Display objects on behalf of the Context. The other
part is global and takes care of communicating with the
DisplayManagerService, handling callbacks, and caching
DisplayInfo objects on behalf of the process.
Implemented support for enumerating Displays and getting
callbacks when displays are added, removed or changed.
Elaborated the roles of DisplayManagerService, DisplayAdapter,
and DisplayDevice. We now support having multiple display
adapters registered, each of which can register multiple display
devices and configure them dynamically.
Added an OverlayDisplayAdapter which is used to simulate
secondary displays by means of overlay windows. Different
configurations of overlays can be selected using a new
setting in the Developer Settings panel. The overlays can
be repositioned and resized by the user for convenience.
At the moment, all displays are mirrors of display 0 and
no display transformations are applied. This will be improved
in future patches.
Refactored the way that the window manager creates its threads.
The OverlayDisplayAdapter needs to be able to use hardware
acceleration so it must share the same UI thread as the Keyguard
and window manager policy. We now handle this explicitly as
part of starting up the system server. This puts us in a
better position to consider how we might want to share (or not
share) Loopers among components.
Overlay displays are disabled when in safe mode or in only-core
mode to reduce the number of dependencies started in these modes.

This solves the problems around active pointer tracking when the

Cleaned up the implementation of Surface and SurfaceSession
to use more consistent naming and structure.

When dispatching input events to the main thread, the event is
handled directly rather than queued. If we have a timeout waiting for
the event to happen, it has to be registered before we call the
dispatcher, otherwise we'll wait for the timeout even though the event
has already been handled.

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.

Add a View.toString() method.
Rename all of the View private flags to have a PFLAG prefix to
avoid going insane trying to figure out which constant goes with
which flag.
Activity.dump() now includes a summary of the activity's view
hierarchy, using the View.toString() method.
All exceptions thrown by FragmentManager now perform a dump of
the owning activity state, where appropriate.

The major goal of this rewrite is to make it easier to implement
power management policies correctly. According, the new
implementation primarily uses state-based rather than event-based
triggers for applying changes to the current power state.
For example, when an application requests that the proximity
sensor be used to manage the screen state (by way of a wake lock),
the power manager makes note of the fact that the set of
wake locks changed. Then it executes a common update function
that recalculates the entire state, first looking at wake locks,
then considering user activity, and eventually determining whether
the screen should be turned on or off. At this point it may
make a request to a component called the DisplayPowerController
to asynchronously update the display's powe state. Likewise,
DisplayPowerController makes note of the updated power request
and schedules its own update function to figure out what needs
to be changed.
The big benefit of this approach is that it's easy to mutate
multiple properties of the power state simultaneously then
apply their joint effects together all at once. Transitions
between states are detected and resolved by the update in
a consistent manner.
The new power manager service has is implemented as a set of
loosely coupled components. For the most part, information
only flows one way through these components (by issuing a
request to that component) although some components support
sending a message back to indicate when the work has been
completed. For example, the DisplayPowerController posts
a callback runnable asynchronously to tell the PowerManagerService
when the display is ready. An important feature of this
approach is that each component neatly encapsulates its
state and maintains its own invariants. Moreover, we do
not need to worry about deadlocks or awkward mutual exclusion
semantics because most of the requests are asynchronous.
The benefits of this design are especially apparent in
the implementation of the screen on / off and brightness
control animations which are able to take advantage of
framework features like properties, ObjectAnimator
and Choreographer.
The screen on / off animation is now the responsibility
of the power manager (instead of surface flinger). This change
makes it much easier to ensure that the animation is properly
coordinated with other power state changes and eliminates
the cause of race conditions in the older implementation.
The because of the userActivity() function has been changed
so that it never wakes the device from sleep. This change
removes ambiguity around forcing or disabling user activity
for various purposes. To wake the device, use wakeUp().
To put it to sleep, use goToSleep(). Simple.
The power manager service interface and API has been significantly
simplified and consolidated. Also fixed some inconsistencies
related to how the minimum and maximum screen brightness setting
was presented in brightness control widgets and enforced behind
the scenes.
At present the following features are implemented:
- Wake locks.
- User activity.
- Wake up / go to sleep.
- Power state broadcasts.
- Battery stats and event log notifications.
- Dreams.
- Proximity screen off.
- Animated screen on / off transitions.
- Auto-dimming.
- Auto-brightness control for the screen backlight with
different timeouts for ramping up versus ramping down.
- Auto-on when plugged or unplugged.
- Stay on when plugged.
- Device administration maximum user activity timeout.
- Application controlled brightness via window manager.
The following features are not yet implemented:
- Reduced user activity timeout for the key guard.
- Reduced user activity timeout for the phone application.
- Coordinating screen on barriers with the window manager.
- Preventing auto-rotation during power state changes.
- Auto-brightness adjustment setting (feature was disabled
in previous version of the power manager service pending
an improved UI design so leaving it out for now).
- Interpolated brightness control (a proposed new scheme
for more compactly specifying auto-brightness levels
in config.xml).
- Button / keyboard backlight control.
- Change window manager to associated WorkSource with
KEEP_SCREEN_ON_FLAG wake lock instead of talking
directly to the battery stats service.
- Optionally support animating screen brightness when
turning on/off instead of playing electron beam animation
(config_animateScreenLights).

This allows you to, say, make a Context whose configuration
is set to a different density than the actual density of the device.
The main API is Context.createConfigurationContext(). There is
also a new API on ContextThemeWrapper that allows you to apply
an override context before its resources are retrieved, which
addresses some feature requests from developers to be able to
customize the context their app is running in.
