Optimize system bar background drawable.

Out with TransitionDrawable.

The new background drawable knows about all possible
background styles, and optimizes the transitions
between them - including picking up from the current
state, force finishing on screen off, and using
SystemClock.elapsedRealtime() for timing.

Don't use transient states for wallpaper animation.

The WindowManagerService member mLowerWallpaperTarget is not stable
throughout an app transition. Relying on it to be stable causes the
intra-wallpaper animation to start out right but after the windows
have been relayed out there is no longer a lower wallpaper target.
This causes the wallpaper to start tracking the animation of the
current wallpaper target rather than remain stable.

Switching to a new variable that saves the state of wallpaper
animation at the start of the animation fixes bug 11240590.

Edge case: overriden system package moved & became privileged in OTA

Because properly continuing permission grants post-OTA has changed
policy to include privilege considerations based on install location,
make sure that we re-evaluate when we determine that the apk has
moved from its pre-OTA location.

Fix leak with transitions when views get removed

Transitions, when started, add an OnPreDrawListener to the current
ViewTreeObserver (which is global to the view hierarchy). This listener
is removed when the listener is called.

It is possible to add this listener and then remove the view from
the hierarchy before the listener is called. This could result in
either the listener not getting called at all (since there was no
drawing event) or (in the case of this bug) the listener getting called
when the sceneRoot had no AttachInfo (which is the case when that
root has been removed from the hierarchy). This results in the listener
trying to remove itself from a *different* ViewTreeObserver than the one
it added itself to, leaving the actual listener still sitting on a list
of listeners in that original VTO. This can result in a growing list of
listeners and a growing amount of work that gets done on every frame.
It can also lead to a serious memory leak, since the objects referred to
by the transition may be non-trivial (as in the case of this bug).

The fix is to add another mechanism for the listener to get removed.
Specifically, we now listen for detach events on the sceneRoot. If that
view gets detached before the listener is called, then we have a chance to
remove it from the correct VTO before the AttachInfo becomes null.

Fix issue #11323037: Android apk incorrectly marked as running in app processes

The android package is now a special case, not being added to the package list
when creating a multi-process component.  There is no need, since this package
is actually the framework itself which must be loaded in every process.

Also cleaned up some of the procstats dump output to help see what is going
on here.

Update roots when data cleared, refresh UI.

Data cleared usually means accounts went away, so kick off roots
refresh.  Also update any visible UI after a refresh finishes.
