We now keep track of all the threads that are stopped, and
print stacks for all of them. Also more threads are now adding
themselves to the watchdog.
Unfortunately the stack we get from threads is far less useful
than the stacks from the ANR report, because these don't include
any information about the lock the thread is blocked on and what
thread is holding that lock. For example, here is a test of the
log output from causing a hang in the system process:

- Add logging for assigning home stack to non-home task to track down
bug. And maybe fix bug.
- Add template parameter to ArrayList.

Because the resolve activity always assumes CATEGORY_DEFAULT, there are odd
cases where apps with malformed intent filters wind up interfering with
users' ability to specify a preferred launcher app.

When a root activity is finishing and it is supposed to return to
home make sure there are only lower activities waiting to start before
going home.
Fixes bug 8632206.
Various other refactorings for efficiency.

IActivityController has a new callback which the Watchdog calls
when it detects that the system process is hung. This may be
use full monkey. All hail the monkey!
Also add a new private feature to Binder to be able to turn off
all incoming dump() calls to a process. The watchdog uses this
when it reports it is hung, so that if someone, say, wants to
collect a bug report at this point they won't get stuck waiting
for things that are all busted.

- Replace calls to ActivityStack.resumeTopActivity() with calls to
ActivityStackSupervisor.resumeTopActivities().
- Move dim layers from display scope to stack scope. This applies to
both the animation background dim layer and the FLAG_DIM_BEHIND dim
layer.
- Move windows on stacks that are not targeting wallpaper above the
wallpaper. Otherwise wallpaper placement hides the non-focused stacks.

Add a test for being the top task when closing the last activity in a
task. Without this test, if the last activity in a task was flagged to
return to the home activity on completion but that activity had
launched a new task we would not go to the new task but would instead
launch the home activity.
Fixes bug 8775949.

To help correlate battery usage against actual foreground app usage,
start tracking time on a per UID basis. It uses the nesting feature
of StopwatchTimer to track multiple PIDs inside the same UID.
Improves units on docs, and persists foreground CPU time with a
consistent ordering. Reports foreground activities time and
foreground CPU time.

This gives us matching pause/resume calls to updateUsageStats(),
since configuration changes never report the pause event.

- Continue to display the home screen for non-fullscreen activities
such as Download. Previously launching Download from home would
display Download on top of the previous activity on the user activity
stack.
- Fix NPE when DEBUG_PROVIDER is true.

- Save and restore WindowManager stack states.
- Maintain ActivityManager activity states based on the stack
the activity is in.
Fixes bug 8646641.
Change-Id: I16c76c7708ab49121c3884a7e5bf219898b92d3f
- New InputEventReceiver for detecting taps outside of focused stack
boundaries.
- Fixed bug that wasn't pausing the non-focused window when returning
home.

Mid-course corrections.
- Simplify ActivityStackSupervisor and ActivityStack constructors to
get passed parameters from ActivityManagerService.
- Store WindowManagerService referecne locally in
ActivityStackSupervisor and ActivityStack.
- Rename getTopStack to getFocusedStack in ActivityStackSupervisor
and ActivityManagerService.
- Move mWaitingActivityLaunched/reportActivityLaunchedLocked and
mWaitingActivityVisible/reportActivityVisibleLocked from ActivityStack
to ActivityStackSupervisor.
- Moved reportResumedActivity to ActivityStackSupervisor.
- Added a Handler to ActivityStackSupervisor. Will populate it on next
CL.

- 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.
Change-Id: I8d3c806234511697bc209ab99890730ffa514d20
- 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.

When granting a Uri permission with new PERSIST_GRANT_URI_PERMISSION
flag, persist that grant across device reboots until explicitly
revoked. Adds new persistedModeFlags dimension to UriPermission,
and moves all flag mutation into UriPermission for clarity. Adds
flag documentation. Only inflate HashSet as needed.
Write persisted grants into XML file, saving based on source and
target package name and user handle. Sanity check grants when
parsing.
Wipe all grants from/to a package when uninstalled, and wipe any
transient grants when a package or user is force stopped.
Persistable grants are always considered "needed."

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

1. This allows UiAutomation type tests to run as if an
android monkey test is running. This allows applications
that recognize that they are drive by a test framework and
avoid performing certain actions such as calling 911.
2. Fixed a bug where the UiAutomation#disconnect() was not
called when the instrumentation is shutdown.

Some permissions are associated with gids, so we need to
kill any running processes if their permission is revoked.
We will do this for any permission being revoked, since
the association between gids and permissions can change
over time.
