Fade the pointer spot when swiping or performing a freeform
gesture.
Support configuring the gesture mode in the device IDC file.
Added workaround for devices that report individual finger
movements one at a time instead of all at once.

The mapper sends a DOWN when the finger is released then starts
a short timer. If the finger is not pressed again before the timer
elapses, then the mapper sends an UP to complete the tap. If the
finger is pressed again then the mapper starts sending MOVEs
as part of a drag.
Double/triple taps work as intended because we also start watching
for a new tap when the finger is pressed again. If a new tap
occurs the old tap is also finished. So each individual finger
short press/release cycle constitutes a distinct tap.

Added a new PointerIcon API (hidden for now) for loading
pointer icons.
Fixed a starvation problem in the native Looper's sendMessage
implementation which caused new messages to be posted ahead
of old messages sent with sendMessageDelayed.
Redesigned the touch pad gestures to be defined in terms of
more fluid finger / spot movements. The objective is to reinforce
the natural mapping between fingers and spots which means there
must not be any discontinuities in spot motion relative to
the fingers.
Removed the SpotController stub and folded its responsibilities
into PointerController.

Refactored PointerController to extract the surface management
code to a new component called a SpriteController so that it can
be used to move finger tracking spots around the screen as well.
The SpriteController is designed to fully decouple the client from
any latency introduced by surface transactions and drawing.
All sprite updates are performed asynchronously on the Looper using
a copy of the sprite state.
Added a stub SpotController implementation for touch pad UX.
It will be implemented in a subsequent patch.
Fixed a little bug in pointer orientation changes when entering
DISPLAY_ORIENTATION_90 the x offset was clobbered.

Some drivers report individual finger updates one at a time
instead of all at once. When 10 fingers are down, this can
cause the framework to have to handle 10 times as many events
each with 10 times as much data. Applications like
PointerLocation would get significantly bogged down by all
of the redundant samples.
This change coalesces samples that are closely spaced in time,
before they are dispatched, as part of the motion event batching
protocol.
Increased the size of the InputChannel shared memory buffer so
that applications can catch up faster if they accumulate a
backlog of samples.

This enlarges the window of opportunity for batching to
encompass time spent for the window to become ready (while it is
busy processing the last event).

Also fix not writing the settings file when an admin is removed.
And take care of an old to-do about not removing an admin until
after it has received the broadcast about it being disabled.

Also be more careful about canceling fallback keys during focus
transitions, when the application handles the key, or when the
policy decides to do something different.
Fixed a crash due to JNI CallObjectMethod returning an undefined
value (not null) when an exception is thrown.
Fixed a crash due to the policy trying to create a Dialog for
recent apps on the dispatcher thread. It should happen on the
policy's Looper instead.

Fix a bug where we were always setting the focused application
handle to NULL. This broke ANR processing while starting
applications and caused input events to be dropped while
starting applications.

When 10 fingers are down, reduces the CPU time spent by the InputReader
thread from ~30% to ~5% on Stingray.

4 hours is excessive, and we want to save bandwidth on the NTP servers

Added a timeout mechanism to EventHub and InputReader so that
InputMappers can request timeouts to perform delayed processing of
input when needed.

Replaced VelocityTracker with a faster and more accurate
native implementation. This avoids the duplicate maintenance
overhead of having two implementations.
The new algorithm requires that the sample duration be at least
10ms in order to contribute to the velocity calculation. This
ensures that the velocity is not severely overestimated when
samples arrive in bursts.
The new algorithm computes the exponentially weighted moving
average using weights based on the relative duration of successive
sample periods.
The new algorithm is also more careful about how it handles
individual pointers going down or up and their effects on the
collected movement traces. The intent is to preserve the last
known velocity of pointers as they go up while also ensuring
that other motion samples do not count twice in that case.

1. Single finger tap performs a click.
2. Single finger movement moves the pointer (hovers).
3. Button press plus movement performs click or drag.
While dragging, the pointer follows the finger that is moving
fastest. This is important if there are additional fingers
down on the touch pad for the purpose of applying force
to an integrated button underneath.
4. Two fingers near each other moving in the same direction
are coalesced as a swipe gesture under the pointer.
5. Two or more fingers moving in arbitrary directions are
transformed into touches in the vicinity of the pointer.
This makes scale/zoom and rotate gestures possible.
Added a native VelocityTracker implementation to enable intelligent
switching of the active pointer during drags.
