Coalesce input events that arrive faster than 333Hz.
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.
Added logging code to help measure input dispatch and drawing
latency issues in the view hierarchy. See ViewDebug.DEBUG_LATENCY.

Add a little input event consistency verifier.
The idea is to assist with debugging by identifying cases in which
the input event stream is corrupted.

Add input filter mechanism for accessibility.
This patch adds a mechanism for capturing, filtering, transforming
and injecting input events at a very low level before the input
dispatcher attempts to deliver them to applications. At this time,
the mechanism is only intended to be used by the accessibility
system to implement built-in system-level accessibility affordances.
The accessibility input filter is currently just a stub.
It logs the input events receives and reinjects them unchanged,
except that it transforms KEYCODE_Q into KEYCODE_Z.
Currently, the accessibility input filter is installed whenever
accessibility is enabled. We'll probably want to change that
so it only enables the input filter when a screen reader is
installed and we want touch exploration.

Add support for arbitrary axes in MotionEvents.
This change makes it possible to extend the set of axes that
are reported in MotionEvents by defining new axis constants.
The MotionEvent object is now backed by its C++ counterpart
to avoid having to maintain multiple representations of the
same data.

DO NOT MERGE: Fix input event injection ANRs on UI thread.
Added a new asynchronous injection mode and made the existing
synchronization mechanism more robust.

Fix bug with phantom input windows.
Add dumpsys integration for the native input dispatcher.
Add some InputDevice API stubs.
Add an appendFormat helper method to String8 for printf style
string formatting mainly for debugging purposes.
Use generic ArrayList<WindowState> everywhere in WindowManagerService
to eliminate unnecessary casts all over.

Add support for new input sources.
Added several new coordinate values to MotionEvents to capture
touch major/minor area, tool major/minor area and orientation.
Renamed NDK input constants per convention.
Added InputDevice class in Java which will eventually provide
useful information about available input devices.
Added APIs for manufacturing new MotionEvent objects with multiple
pointers and all necessary coordinate data.
Fixed a bug in the input dispatcher where it could get stuck with
a pointer down forever.
Fixed a bug in the WindowManager where the input window list could
end up containing stale removed windows.
Fixed a bug in the WindowManager where the input channel was being
removed only after the final animation transition had taken place
which caused spurious WINDOW DIED log messages to be printed.
