Uses a linked list for efficient pointer addition and removal.
When possible, makes use of the fact that pointer ids are usually in
sorted order to avoid quadratic time lookups when adding new data.
Fixed an incorrect assumption that the pointer count would always change
when old pointers were removed.
Also fixed a bug in InputQueue FinishedCallback recycling.

getBondedDevices() *might* work if called before the Bluetooth
State intent is broadcasted. However, this can cause ANRs and problems.
This API was updated to return null, if called before the intent
is received. However, this might cause existing apps to crash. Return
an empty set instead.

For example, Settings app makes calls to get Bonded Devices
before Bluetooth is on. This leads to ANRs and will
prevent autoconnection.

COMMENT ONLY change to fix some formatting glitches and
Since orientation sensing has been an issue for numerous users, I
decided a spend a little time experimenting with some possible
improvements. I've settled on a couple major changes:
* Perform all lowpass filtering in spherical coordinates, not
cartesian. Since the rotations are what we're really concerned
with, this makes more sense and gives more consistent results.
* Introduce a system of tracking "distrust" in the current data, based
on external acceleration and on tilt. The basic idea is after a
signal of unreliable data -- repeated acceleration or
nearly-horizontal tilt -- we wait for things to "stabilize" for some
number of ticks before we start trusting the data again. This is an
extension of the basic lowpass filtering. One simple example is
after the phone is picked up off a table, we ignore the first few
readings. Another example is while the phone is under external
acceleration for a while (i.e. in a car mount on a rough road), if a
single "good" reading comes in, we distrust it, under the assumption
that it was probably just a lucky reading (i.e. the magnitude
happened to be close to that of gravity by chance).
These changes have allowed me to relax other constraints, such as the
filtering time constants, the maximum deviation from gravity, and the
max tilt before we start distrusting data.
The net effect is that orientation changes happen more quickly and can
happen under a wider variety of conditions, but false changes due to
tilt and acceleration are still avoided well. I think the improvement
is subtle, but it's the best I've come up with in my limited time.
I've also included some refactoring and additonal comments to try and
further clarify the (somewhat twisted) logic.

When a movePackage operation is requested, don't allow multiple requests
to pile up for one package. Once a move is completed, an observer will
receive the message and be allowed to call movePackage again.

The NotificationManager tries to crash the calling app, but
in the case of a service calling startForeground, the caller
is the ActivityManager, so system_server goes down.
NotificationManagerService#enqueueNotificationInternal is a
new internal-only method that accepts a UID/PID to use when
punishing bogus notifications (such as the one in
http://b/2869787).

The return of parsePackageLite wasn't checked until after it was
deferenced. Move the deference below the null check and remove redundant
set.

Improved PointerLocation tool to use VelocityTracker more efficiently
and correctly when multiple pointers are down.
Fixed a bug in TouchInputMapper where it was not correctly copying
the id to index map in the last touch data. This could cause strange
behavior on secondary pointer up events.
Also added finished callback pooling in InputQueue.

Exposed the new "min delay" sensor property through native and
java sensor apis. This allows the caller to know what is the
maximum rate at which a sensor can return events, or, if a sensor
works in "update" mode (events returned only when the value changes).
Also augmented SensorManager.regusterSensorEvent() so that it can
accept a value in microsecond in addition to the 4 constants already
defined.

Added a new asynchronous injection mode and made the existing
synchronization mechanism more robust.

Refactored the input reader so that each raw input protocol is handled
by a separate subclass of the new InputMapper type. This way, behaviors
pertaining to keyboard, trackballs, touchscreens, switches and other
devices are clearly distinguished for improved maintainability.
Added partial support for describing capabilities of input devices
(incomplete and untested for now, will be fleshed out in later commits).
Simplified EventHub interface somewhat since InputReader is taking over
more of the work.
Cleaned up some of the interactions between InputManager and
WindowManagerService related to reading input state.
Fixed swiping finger from screen edge into display area.
Added logging of device information to 'dumpsys window'.
