This introduces four generic thread that services can
use in the system process:
- Background: part of the framework for all processes, for
work that is purely background (no timing constraint).
- UI: for time-critical display of UI.
- Foreground: normal foreground work.
- IO: performing IO operations.
I went through and moved services into these threads in the
places I felt relatively comfortable about understanding what
they are doing. There are still a bunch more we need to look
at -- lots of networking stuff left, 3 or so different native
daemon connectors which I didn't know how much would block,
audio stuff, etc.
Also updated Watchdog to be aware of and check these new
threads, with a new API for other threads to also participate
in this checking.

- Putting the stack frame above the highest app window layer ends up
putting it over the IME when the caret popup is showing. This puts
the stack frame layer above the highest non-child window layer.
- Also change the timing so the layer isn't applied until all other
layers are also being applied.

Missed a spot where an activity that is launching another was not
being paused. Fixes bug 8640130. At least in one case.
Release mWindowMap as soon as it is no longer needed.

Grabbing StackTapDetector before grabbing mWindowMap doesn't play well
with grabbing mWindowMap and then StackTapDetector.

- Save and restore WindowManager stack states.
- Maintain ActivityManager activity states based on the stack
the activity is in.
Fixes bug 8646641.

- New InputEventReceiver for detecting taps outside of focused stack
boundaries.
- Fixed bug that wasn't pausing the non-focused window when returning
home.

- Did not handle the case where mTaskIdToTask returned null.
Fixes bug 8646178.
- updateInputWindowsLw() was being called in removeWindows
immediately after it was called in performLayoutAndUpdateSurfaces.

- Fix back button behavior with two stacks. Stopping activities were
held in that state indefinitely. This change causes IDLE_NOW_MSG to
be sent immediately for the last activity in a stack.
- Touch in non-focused stack was being ignored because of focus tests
in AbsListView.
- Change the focused stack when the activity focus changes. Renamed
mMainStack to mFocusedStack to reflect this.
- Resume all top stack activities when resuming.
- Assign intent task to ActivityRecord if it doesn't have a task.
Fixes bug 8433463.

- Add taskId parameter to createStack() so stacks are pre-populated
with a task.
- Keep track of stack access order in DisplayContent so getTasks
returns in MRU order.
- Set touchableRegion in InputMonitor so modal touching does not
extend beyond stack boundary.
- Fix stack merging so that deleting a stack results in a new
stack the size of the two children.

Split stacks and move tasks between them. Layout the windows
according to the new stack split.
After layout content rectangles are known split the available area
between all stack boxes. Then use those values for future layout.
Provide stack contents to ActivityManager.

One for home activity(s), one for other activities. Coordination
between the stacks is handled by the ActivityStackSupervisor.

The min layer was set to only show the windows that matched
the specified app token. But that meant when dialogs were
launched it only showed the dialogs and not the background
windows.
Added improved debugging.

If LockScreen is enhanced using SurfaceView/GLSurfaceView,
deadlock problem between LockScreen and WindowManagerService
can occur because of IWindow.resized() callback.
And it must lead to watchdog and reset.
IWindow.resized() callback is one-way function so calling resized()
callback of a remote IWindow object is never blocked.
However, calling resized() callback of a local IWindow object
(LockScreen is running on the same system_server process)
is always blocked until resized() callback returns.
Because resized() callback of SurfaceView/GLSurfaceView can lead to
WindowManagerService.relayoutWindow() call, deadlock can occur
between relayoutWindow() and performLayoutAndPlaceSurfacesLockedInner().
(Both functions need locking mWindowMap)
So this patch simulate one-way call when calling resized() callback
of a local IWindow object.

When a tablet rotates, FUL must be stopped and restarted in a new
position. 90 degree rotations cause a configuration change, causing
FUL to be automatically reconstructed in the new location. However,
a 180 degree rotation is not a configuration change, so FUL was not
restarting. A 180 degree rotation happens more often than one might
think. If you set the tablet down and later picked it up in the
opposite orientation, FUL would not work prior to this fix.
This change adds a rotation watcher to KeyguardFaceUnlockView. It
watches for 180 degree rotations and stops and restarts FUL
accordingly.
The rotation watcher callback must be unregistered when
KeyguardFaceUnlockView is recreated (as during 90 degree rotation
changes), otherwise the number of rotation watcher callbacks will keep
growing and they will never go away. This is a problem not just
because there are many callbacks hanging around, but also because the
old callbacks end up trying to access biometric unlock views that no
longer exist, resulting in crashes. So, a simple function was added
to the window manager to unregister a rotation watcher.

Pause and retry capturing a thumbnail if the window hasn't yet
been drawn. Still will show black thumbnails if recents is pressed
before window has anything drawn.

The root cause is:
There is a defect in window manager service: When a new
activity that can be ime target is added into window manager
but the Z order of input method window don't need to be
changed, then the target app token of input method window
would not be updated to new one. This defect may cause that
the layer of input method window is calculated incorrectly.
The solution:
Correct the target app token for input method window.

- Create new classes for Stacks on WindowManager.
- Stop using DisplayContent methods and members:
addAppToken(),
removeAppToken(),
setAppTaskId(),
removeTask(),
mTaskIdToDisplayContents,
mTaskIdToTask.
- Start using WindowManagerService.createTask().
- Establish hierarchy of references: AppWindowToken=>Task=>
TaskStack=>StackBox=>DisplayContent.
- Clean up StackBox, TaskStack, and Task.
