Keep around GET_TASKS as a permission available to apps, so apps still
think they have it and don't get all uppity because they don't.
Add a new REAL_GET_TASKS that is the actual permission now.
Plus some temporary compatibility code until everyone can transition
fromn GET_TASKS to REAL_GET_TASKS.

The motivation is an API change: FloatMath is going to be
deprecated and/or removed. Performance is not the goal of
this change.
That said...
Math is faster than FloatMath with AOT compilation.
While making the change, occurances of:
{Float}Math.sqrt(x * x + y * y) and
{Float}Math.sqrt({Float}Math.pow(x, 2) + {Float}Math.pow(y, 2))
have been replaced with:
{(float)} Math.hypot(x, y)
Right now there is no runtime intrinsic for hypot so is not faster
in all cases for AOT compilation:
Math.sqrt(x * x + y * y) is faster than Math.hypot(x, y) with
AOT, but all other combinations of FloatMath, use of pow() etc.
are slower than hypot().
hypot() has the advantage of being self documenting and
could be optimized in future. None of the behavior differences
around NaN and rounding appear to be important for the cases
looked at: they all assume results and arguments are in range
and usually the results are cast to float.
Different implementations measured on hammerhead / L:

Improve the warning logs when setting up preferred activities
to help identify when there are issues and what they are. Also
improve the algorithm a little to still apply permissions when
resetting them and there are additional third party apps, as long
as the additional app is something like another browser and the
preferred activity being set is more specific (has a better match).
And add an example of using manifest-based preferred activities
in to ActivityTest -- and yes it DOES work! :p

When the system time is changed, the UsageStats API
will modify all existing entries to correspond with the
new time change. If the time changed when the device was
off, stats in the future will be deleted.

BUG: 17424511
Introduce an "isOverrideDeadlineExpired" which will allow clients
to know when they are being run due to an expiry.
Nb that we check deadline expiry by checking that the constraints on
the job are not satisfied at execution time. Really this is the same
thing, as a job will not be run without its constraints being met,
unless the job has expired.

At the same time, remove the group alpha since we did not follow the convention
that group's alpha should apply together, not separately to each elements.

Issue #17394151: WallpaperService / Engines need to get notified
of WindowInsets
Issue #17394203 Wallpapers need a system API to be shifted in order
to support burn in protection
Adds a new API on WallpaperManager to set additional offsets to
make wallpapers extend beyond the display size.
Insets are now reported to wallpapers, to use as they may. This
includes information about the above offsets, so they can place
their content within the visible area. And to help with this, also
expose the stable offsets APIs in WindowInsets which is also very
useful information for the wallpaper.
Another new API on WallpaperManager to set a raw offset to apply
to the wallpaper window, forcing it to move on the screen regardless
of what the wallpaper is drawing.
Fix wallpapers when used with overscan enabled, so they still extend
out across the entire screen. Conveniently, the above new window
insets information is very useful for this case as well!
And a new wallpaper test app for all this stuff.

Add a new activity attribute, resumeWhilePausing, that allows an
activity specifying it to immediately start running without waiting
for the previous activity to pause. The recents activity is updated
to use this.
The implementation of this is ultimately fairly simple -- if we are
in the path of resuming such an activity, and find that we first need
to pause the existing activity, then within the activity manager we
do the regular pause flow but act like it has immediately finished
pausing right then so that we can immediately go on to the resume.
To make this clean, we tell the activity when asking it to pause that
it should not come back and tell us it is done, because we aren't in
any way waiting for it.
One potentially important change I needed to make here is the pause
callback no longer provides the saved persistent state, because we
now can't count on that callback happening. I don't think there was
really any utility in this anyway -- all modern apps will have their
save state flow happen as part of stopping, not pausing, so we'll
only capture that saved state when the stop is reported back anyway.
And since we do send the saved state back when stopping, it would
always blow away whatever we had gotten at the pause.
Finally, update the documentation for AppTask.startActivity(), and
fix the implementation handling that to be cleaner -- we need to
deal with inTask first before getting in to "oh noes add NEW_TASK
if this isn't coming from a calling activity" flow.

- Rename listeners to callbacks. Listeners are single-method and are interfaces,
while callbacks are abstract may get more methods in the future.
- Use register/unregister for registering callbacks, not add/remove.

It would be good to actually bring the task to the front.
Also, make the flow when inTask is provided better match what happens when
we go looking for a task on our own.
And this includes another fix that was supposed to be part of a different
change but I forgot this class is part of the framework project now.
