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).

An odd alignment of the stars can end up with all of mAppToken.allDrawn
animating and mAppToken.startingDisplayed all false, and animation not
null. In such a case we can continue returning false but still pass
the test in WindowAnimator.updateWindowsAndRotation setting
wasAnimating to true. The combination continually sets the
FINISH_LAYOUT_REDO_WALLPAPER bit in mPendingLayoutChanges.
Fixes bug 6304838.

Stop animate() from using the mWindows maintained by
WindowManagerService. Animating WindowStateAnimators are now drawn from
a HashSet maintained by WindowAnimator and containing just those
WindowStateAnimators that have Surfaces.
When starting a move animation do not place parameters directly into
the WindowStateAnimator, instead pass them through the Handler.
Also removed synchronization points from mWindows/mAppTokens
add/remove.
Simplified input injection API down to just one call.
Removed all input state reading API. It was only used by the
window manager policy and required a permission that applications
could not obtain. READ_INPUT_STATE is now unused and deprecated.

Dimming was constantly being turned off if it wasn't time to turn it
on. This caused endless reentry into the Window Manager and consumed
lots of CPU.

Extracted the input system from the window manager service into
a new input manager service. This will make it easier to
offer new input-related features to applications.
Cleaned up the input manager service JNI layer somewhat to get rid
of all of the unnecessary checks for whether the input manager
had been initialized. Simplified the callback layer as well.

A previous check in changed the collection we were pulling exiting
AppWindowTokens from. Instead of pulling them from mExitingAppTokens
they came from mAppTokens and hence were not animated away.

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.

- Isolate DimAnimator animation from the layout side.
- Isolate mWallpaperForceHidingChanged and mOrientationChangeComplete
from the animation side.
- Eliminate a redundant setting of mOrientationChangeComplete to true.
It was already true at that point.
- Synchronize changes to mWindows and mAppTokens on mAnimator. This is
a nop until we go to multiple threads.

Perform the set-transparent-region-hint operation outside of the
WindowManagerService loop. This is to isolate the Surface operation
from the WindowManagerService inner loop.
Similarly, defer the setWallpaperOffset call so it's animation is not
coupled to the WindowManagerService inner loop.
Note that both operations are still being done on the
WindowManagerService thread.

The main change is a few new flags you can supply to
View.setSystemUiVisibility(). One is a new visibility mode,
SYSTEM_UI_FLAG_FULLSCREEN, which is basically the same as
the global FLAG_FULLSCREEN option for windows, but driven as
part of the system UI state.
There are also three new flags for telling the framework that you
would like to have your application's UI ignore screen
decorations -- SYSTEM_UI_FLAG_LAYOUT_NO_NAVIGATION for going
behind the navigation bar and SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
for ignoring full screen decorations (that is the status bar).
In combination with this you can use SYSTEM_UI_FLAG_LAYOUT_STABLE
to have the framework report consistent insets to your application.
When using NO_NAVIGATION, when the user taps the screen we now
also automatically clear ONLY_CONTENT, so that we atomically show
both UI elements. This should make it easy for apps like video
players that want to move between fully full-screen and regular
modes.
The ActionBar has also been extended when in overlay mode so
that it will adjust the system window insets to also account
for its space, and allow it to be hidden using the new
SYSTEM_UI_FLAG_FULLSCREEN.

Improved how the various callbacks are managed and sequenced
to reduce code duplication.
Added a heuristic to avoid postponing traversals until
the next vsync frame if we did not actually do any drawing during
the previous frame. This helps in the very common case where
drawing occurs in response to input.

The layer adjustment to an animating window upon completion was masking
the window behind the mWindowAnimationBackgroundSurface, a DimSurface.
