We need to be able to perform very lengthy operations on some threads
(e.g. the I/O thread responsible for installing multi-gigabyte APKs) but
still have long-run deadlock/hang detection applied to those threads.
Previously the watchdog mechanism applied the same policy to all
monitored threads: unresponsive after 60 seconds => restart the system.
Now, each monitored entity can have its own independent timeout after
which the watchdog declares deadlock and restarts the runtime. The
halfway-finished intermediate thread stacks are dumped based on the
specific entity's declared timeout, not the global 30 second checking
interval.
With that new mechanism in place, the Package Manager's lengthy-I/O
thread watchdog timeout is raised to 10 minutes.

The previous jank improvement only worked when closing
an app, not when bringing one forward (hitting home button).
This should cover the specific case that is being missed: Having the
Home task being brought to front over a translucent window, with
a wallpaper behind both tasks.

When a non-fullscreen task over home launches another non-fullscreen
task then the home task might not be displayed. Looking all the way
down the task stacks until reaching a visible, fullscreen activity or
home provides the right information.

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.

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.

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.

When finishing or stopping an activity the code was automatically
refocusing to the next activity on the same stack independent of the
task's onTopOfHome flag. When the activity eventually finished or
stopped it would then honor the onTopOfHome flag.
This fix examines the onTopOfHome flag and arranges the focus
correctly if home is the next activity to run.
Fixes bug 11318263.

There were circumstances where mFocusedStack could be assigned the
home stack. If this were ever to occur then all subsequent tasks would
be put on the home stack. This fix ensures that there is no way that
mFocusedStack will ever be assigned to the home task.

The possibility existed that an activity was set to a task that it was
already being set to. If that were to happen, and it was the only
activity in the only task of the stack the stack would be deleted.
This fixes that situation and logs it as well to confirm that it does
fix bug 11272935. Logging to be deleted upon successful monkey run
exhibiting the log.
