This patch adds a native C++ Builder object for StaticLayout to
complement the Java one introduced in a previous patch.
The Builder object contains state used in constructing a layout, as well
as temporary buffers, to avoid having to allocate such. In particular,
it holds a break iterator, so avoids the cost of constructing that in
the common case of a single locale.

Fix a bunch of places where mNativeBitmap was being
poked at directly, switch them either to the NDK API
or to GraphicsJNI where it made sense

Clean up and increase readability of internal handling of lock task mode APIs.
Add a public API to query the lock task mode state with pinned and locked as
possible outcomes. Additionally, change wording in lock task toasts when in
locked mode and update the javadoc regarding onLockTaskModeEntering and
onLockTaskModeExiting to represent the actual behaviour.

Add a simple ArraySet.removeAll(ArraySet) method. This avoids two
allocations, a MapCollections helper and an Iterator object, over
the removeAll(Collection) code.
KeySetManagerService heavily calls removeAll during boot (about 9K
times in AOSP). This reduces GC stress and optimizes the removal
(about half the time the removed collection has only one element).
The removal method in KeySetManagerService is also done under a lock,
so that it gates parallelization efforts in PackageManagerService.

A ChooserTargetService can be implemented by apps that wish to offer
additional deep-link targets for the system intent chooser to in turn
offer to the user. This allows apps to create contextually relevant
shortcuts for UI flows that would otherwise require several steps of
explicit disambiguation. For example, a chat app might offer one-touch
access to recent conversations when sharing a photo to it from
elsewhere.
The chooser implementation must limit the number of
ChooserTargetServices it elects to query in order to respect available
system resources. Only the system chooser is permitted to bind to a
ChooserTargetService.

This patch refactors construction of StaticLayout to use an explicit
Builder object, which is intended to hold state used for constructing
the layout but not needed for merely reading out the results.
Builder objects are allocated from a pool and explicitly recycled,
so there is insignificant additional allocation cost.
This patch has very little impact on performance (it does avoid
allocating a FontMetricsInt object) but opens the way for significant
performance and functionality improvements as more of the Builder
functionality migrates to native code.

A device initializer is an application that is allowed to run
during user provisioning on device owner devices. During
device provisioning (or, user provisioning of the first user
of the device), a device initializer is granted device owner
permissions. During secondary user provisioning, a device
initializer is granted profile owner permissions. Once
provisioning is complete for a user, all elevated permissions
are removed from the device initializer and the device admin
component of the app is disabled.

Problems arise if an activity is started in an ActivityView when the
parent activity is not resumed. In particular the ActivityView can
be brought to the front in front of other activities that have been
started by the parent.
This change checks the state of the parent when the ActivityView is
starting and if it is not resumed, throws an Exception.
This change also removes the queueing up of Intents if the surface
does not exist when startActivity is called. Now, the owner of the
ActivityView is notified when the surface becomes available. If
startActivity is called before that notification an Exception will be
thrown.
Fixes bug 19147472.
