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.

The trackball to dpad synthesis was using the MotionEvent's precision
field to determine a threshold for movement but the calculations
involved did not actually make sense for any value of precision
less than 2.0. This worked fine before since the InputReader
hardcodes the trackball's precision to 6.
Injected trackball events may have a different precision which can
result in the thresholds being set inappropriately. For example,
it was not possible to move focus by one unit at a time when
the precision was set to 1.0.
The old code was probably using precision as a way to set a
threshold based on the trackball moving by some minimum number
of physical ticks, in this case 2. But the code will work just
as well if we set an absolute threshold based on distance
traveled given that the input system is already expected to
normalize the trackball movements before delivering them to the
application.
So stop using precision.

These have been deprecated since API level 8 / 9. Plugins are deprecated
overall now, so there's no requirement for apps to call these any more.

Redesigned how ViewRootImpl delivers input events to views,
the IME and to native activities to fix several issues.
The prior change to make IME input event delegation use
InputChannels failed to take into account that InputMethodManager
is a singleton attached to the main looper whereas UI may be
attached to any looper. Consequently interactions with the
InputChannel might occur on the wrong thread. Fixed this
problem by checking the current thread and posting input
events or callbacks to the correct looper when necessary.
NativeActivity has also been broken for a while because the
default event handling logic for joysticks and touch navigation
was unable to dispatch events back into the native activity.
In particular, this meant that DPad synthesis from touch navigation
would not work in any native activity. The plan is to fix
this problem by passing all events through ViewRootImpl as usual
then forwarding them to native activity as needed. This should
greatly simplify IME pre-dispatch and system key handling
and make everything more robust overall.
Fixed issues related to when input events are synthesized.
In particular, added a more robust mechanism to ensure that
synthetic events are canceled appropriately when we discover
that events are no longer being resynthesized (because the
application or IME is handling or dropping them).
The new design is structured as a pipeline with a chain of
responsibility consisting of InputStage objects. Each InputStage
is responsible for some part of handling each input event
such as dispatching to the view hierarchy or to the IME.
As a stage processes an input event, it has the option of
finishing the event, forwarding the event to the next stage
or handling the event asynchronously. Some queueing logic
takes care to ensure that events are forwarded downstream in
the correct order even if they are handled out of order
by a given stage.
Cleaned up the InputMethodManager singleton initialization logic
to make it clearer that it must be attached to the main looper.
We don't actually need to pass this looper around.
Deleted the LatencyTimer class since no one uses it and we have
better ways of measuring latency these days using systrace.
Added a hidden helper to Looper to determine whether the current
thread is the indicated Looper thread.
Note: NativeActivity's IME dispatch is broken by this patch.
This will be fixed later in another patch.

The new media button receiver with only a pending intent (no
component name) could be left hanging if the process that
registered it went away. These semantically need to be tied
to the calling process's lifetime; we now clean them up when
the calling process goes away.
Also added some additional cleanup of media button receivers
when packages change (updated, cleared).
And on top of that, a new "media" command for doing media
things. Currently lets you send media keys and monitor
remote display data.
Oh and finally added a new BaseCommand base class for
implementing these command line utilities.

Adding views to views (possible with the new Overlay API) is weird.
This change moves the view-management facilities of Overlay to a subclass
that is specific to the overlay returned from ViewGroup.getOverlay().
So now you can add drawables to all view overlays, but only add/remove
views to/from the overlay returned from ViewGroup.getOverlay().
Also, the previous approach of using an interface for Overlay was
changed to classes for both ViewOverlay and ViewGroupOverlay.
Finally, this change makes not handling touch correctly the proper,
and documented, behavior of overlay views. There are various tricky issues
to sort out with input in overlays (including click handling as well as focus)
and we don't want developers starting to use overlays as some kind of general
container hierarchy, so we're purposely constraining overlays to have visual-only
behavior.

Add UI support for revoking optional permissions. When the user
taps on an optional permission, two new boxes will appear:
[Cancel] | [Revoke]
Selecting [Revoke] will revoke the permission from the app.
The [Cancel] / [Revoke] options are only shown for apps which support
optional permissions.

This is the best and only way for apps to listen for
notifications: create a NotificationListenerService, wait
for the NoMan to bind to you (as a result of the user
checking a box somewhere in Settings and agreeing to a
scary dialog box), and you'll start receiving notification
posted and dismissed callbacks. Your service, while enabled,
will also be able to clear one or all notifications.
Use this power wisely.
This change moves StatusBarNotification out of
com.android.internal into android.service.notification.
[Internal customers, including System UI and early users of
the system-only listener binder API, will need to be
updated.]

InputChannels are normally duplicated when sent to a remote process
over Binder but this does not happen if the recipient is running within
the system server process. This causes problems for KeyGuard because the
InputMethodManagerService may accidentally dispose the channel
that KeyGuard is using.
Fixed the lifecycle of InputChannels that are managed by the IME
framework. We now return a duplicate of the channel to the application
and then take care to dispose of the duplicate when necessary.
In particular, InputBindResult disposes its InputChannel automatically
when returned through Binder (using PARCELABLE_WRITE_RETURN_VALUE).

Don't install packages where we have multiple, conflicting
<uses-permission> lines for the same permission.
For example, a package which contains:
<uses-permission android:name="android.permission.INTERNET" android:required="false" />
<uses-permission android:name="android.permission.INTERNET" android:required="true" />
will now fail to install.
In addition, this change slightly refactors the code, and creates a new
parseUsesPermission() method.
