Fixes a black flash that occurred when the device was docked
because the UiModeManagerService was launching the Somnambulator
to start the dream when docked. This caused an unnecessary
activity transition and could in fact make dreaming less
reliable than if the UiModeManagerService started the dream itself.
Moved common code from UiModeManagerService and Somnambulator
to Sandman to ensure it is kept in sync.

7296314 Crashing dreams are stuck
7296510 Transition from lock screen to dreaming is really bad
The window layer for dreams is now moved down below the keyguard,
so that some of the expected stuff like crash and ANR dialogs can
be seen on top of them. While doing this, I reorganized how we
define the layers so the constants are just in the switch statement,
so it is much less crazy-making trying to read how things go
together.
We now have some special cases for when a dream is being shown
to turn off its animation if the keyguard is currently shown.
Since we know it will be hiding the keyguard we need it to be
shown immediately so that you don't see whatever is behind it.
Cleaned up some handling of when the lock screen is displayed
while a FLAG_SHOW_WHEN_LOCKED window is displayed, so that the
lockscreen doesn't transiently get shown and mess up the fullscreen
or system UI state. This also fixes problems with any normal
activity that is doing this.
Hid the methods on DreamService for setting lights out mode. It
doesn't make sense to have such methods on DreamService, because
you can just as well do that on your own View that is showing the
dream content, and when you can do that you can fully participate
in the (required) interactions about it such as being told when
the mode goes away.
The DreamService method for going fullscreen now uses the window
flag for doing this, which is what you want, because you want this
state to persistent on that window and not get knocked out if
something above the window tickles the system UI state.
Also fixed the problem where dreams that hid the status bar would
have a jerky animation when going away, since they were causing the
activity behind them to be layed out without the lock screen. This
is a kind-of ugly special case in the window manager right now to
just not layout windows that are behind a dream. Good enough for MR1.

Clearly isolated the DreamManagerService and DreamController
responsibilities. DreamManagerService contains just enough logic to
manage the global synchronous behaviors. All of the asynchronous
behaviors are in DreamController.
Added a new PowerManager function called nap() to request the device
to start napping. If it is a good time to nap, then the
PowerManagerService will call startDream() on the DreamManagerService
to start dreaming.
Fixed a possible multi-user issue by explicitly tracking for
which user a dream service is being started and stopping dreams
when the current user changes. The user id is also passed to
bindService() to ensure that the dream has the right environment.
Fix interactions with docks and the UI mode manager. It is
important that we always send the ACTION_DOCK_EVENT broadcast
to the system so that it can configure audio routing and the like.
When docked, the UI mode manager starts a dock app if there is
one, otherwise it starts a dream.
This change resolves issues with dreams started for reasons other
than a user activity timeout.

- New public APIs to find out when a user goes to the foreground,
background, and is first initializing.
- New activity manager callback to be involved in the user switch
process, allowing other services to let it know when it is safe
to stop freezing the screen.
- Wallpaper service now implements this to handle its user switch,
telling the activity manager when it is done. (Currently this is
only handling the old wallpaper going away, we need a little more
work to correctly wait for the new wallpaper to get added.)
- Lock screen now implements the callback to do its user switch. It
also now locks itself when this happens, instead of relying on
some other entity making sure it is locked.
- Pre-boot broadcasts now go to all users.
- WallpaperManager now has an API to find out if a named wallpaper is
in use by any users.

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.

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).

Rather than normal Activities (which have a host of problems
when used for this purpose), screen savers are now a
special kind of Service that can add views to its own
special window (TYPE_DREAM, in the SCREENSAVER layer).
Dreams are now launched by the power manager; whenever it is
about to turn the screen off, it asks the window manager if
it wants to run a screen saver instead. (http://b/5677408)
Also, the new config_enableDreams bool allows the entire
feature to be switched on or off in one place. It is
currently switched off (and the APIs are all @hidden).

This change simplifies the code associated with receiving input
events from input channels and makes it more robust. It also
does a better job of ensuring that input events are properly
recycled (sometimes we dropped them on the floor).
This change also adds a sequence number to all events, which is
handy for determining whether we are looking at the same event or a
new one, particularly when events are recycled.

As it turns out, it used to be possible for there to be multiple
input events simultaneously in flight in an application. Although
it worked, it made it hard to reason about what was going on.
The problem was somewhat exacerbated by the introduction of a
queue of "InputEventMessage" objects as part of an earlier latency
optimization.
This change restores order from chaos and greatly simplifies the
invariants related to input event dispatch within the application.
