The goal of this is to keep track of what app processes
are doing, to determine who is being abusive, when the system
is getting into memory constrained situations, and help the
user determine how to resolve this.
Right now it doesn't really do any of that, just keeps track
of how long every process has been running since boot.
Also update the activity manager to use "cached" as the terminology
for what it used to interchangeably call hidden and background
processes, and switch ProcessMap over to using ArrayMap.

Dumping per-package data is now much cleaning, and only really
prints information related to the package. Also clean up the
formatting and such of the new activity stack states.

Yay to ArrayMap, letting me get rid of a bunch of temporary
iterators in core code paths like updateOomAdj. (Now I definitely
need an ArraySet to finish that up.)
Also clean up various other things that are doing unnecessary
allocations, clean up some debug output, make more of the debug
output respect package filtering.

In case of singletone provider, we don't count it in the guset user.
After we remove it from the array, and resize the array, need to move
iterator back.

- Removed IActivityManager.getStacks() since getStackBoxes() is better.
- Made createStacks operate relative to StackBox instead of TaskStack.
- Made resizeStack into resizeStackBox.

First step in permitting StackBoxes to be manipulated by user.

- Rename "Swappable PSS" to "PSS Clean" which I think is what it
means and is consistent with the other memory metrics.
- Split at the top level the dalvik heap from other dalvik allocations,
so when you look on the dalvik allocations line things are consistent
with the allocator's data and it is clear what are app allocations vs.
other data in dalvik.
- Don't print lines that are all 0.
- Don't print the detailed Dalvik allocation data by default; add a new
option to have it printed.
Here's what a typical system process dump now looks like:

- Add all changing windows to mResizingWindows when an ActivityStack
is resized.
- Stop calling TaskStack.setBounds if the bounds haven't changed.
- Make moving a task from one stack to another work properly.
- Eliminate unused methods and redundant variables in WindowState and
WindowStateAnimator.

mGoingToSleepActivities, mGoingToSleep, mSleepTimeout from
ActivityStack to ActivityStackSupervisor.
- Fix bug that was causing mGoingToSleepActivities to always be
empty.
- Add more debug logging.

The screenshots were capturing the entire screen. Now they are limited

Add debug for stack states.

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:

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.

home make sure there are only lower activities waiting to start before
going home.

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.

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

foreground CPU time.
