Added the MotionEvent.FLAG_WINDOW_IS_OBSCURED flag which is set by the
input manager whenever another visible window is partly or wholly obscured
the target of a touch event so that applications can filter touches
accordingly.
Added a "filterTouchesWhenObscured" attribute to View which can be used to
enable filtering of touches when the view's window is obscured.

TODO: Currently disabled for WebView. Assets used for the glow effect
need to be themable/styleable. Overscroll effect should take place
even when the user did not grab the widget within actual content.

Finished the input device capability API.
Added a mechanism for calibrating touch devices to obtain more
accurate information about the touch contact area.
Improved pointer location to show new coordinates and capabilities.
Optimized pointer location display and formatting to avoid allocating large
numbers of temporary objects. The GC churn was causing the application to
stutter very badly when more than a couple of fingers were down).
Added more diagnostics.

to return the selected text.
setComposingRegion:
The TextView may choose to highlight the text in some way (underline for now) to indicate
that the text is selected for correction, if the IME wants to provider alternatives.
Choosing an alternative in the IME can then call IC.commitText() to replace the highlighted
(not selected) text with a different candidate.
This change also ensures that any existing spans/styles are not wiped out. So we can now
correct rich text as well.
getSelectedText:
This is a convenience to get the selected text instead of using extracted text that is
more heavy weight. Existing getTextBeforeCursor() and getTextAfterCursor() fail to
retrieve the selected text, only what's before and after the selection.

This change makes the window manager pass the currently displayed
orientation to the WindowOrientationListener each time to calls to get
the currently sensed orientation. Now, when the
WindowOrientationListener doesn't know for sure what the orientation
of the device should be (for example, if the sensed orientation is
flat on a table), then it trusts the already-displayed orientation,
rather than trusting whatever sensors reading it most recently
received.
The main use case this addresses is:
* user uses device in portrait
* user turns off device, puts it in pocket
* while in pocket, screen gets turned on, activating orientaiton
sensor, which senses landscape orientation
* screen timed out
* user takes device out, places it on a table (or looks down at it,
holding it flat), and unlocks it
Previously, when the device was unlocked, the
WindowOrientationListener would return landscape orientation based on
its previous sensor readings. Now, it will override those previous
readings because it knows they never actually took effect and the
device is presently flat.
This change also slightly modifies the way we handle flat orientation,
now completely ignoring data when the tilt distrust is nonzero (even
if the current sensor reading shows non-tilted).

This change involves adding a new method to IWindowManager,
monitorInput() that returns an InputChannel to receive a copy of all
input that is dispatched to applications. The caller must have
the READ_INPUT_STATE permission to make this request (similar to
other window manager methods such as getKeycodeState).

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.

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.

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.

Added a new asynchronous injection mode and made the existing
synchronization mechanism more robust.
Change-Id: Ia4aa04fd9b75ea2461a844c5b7933c831c1027e6
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'.
Change-Id: I17faffc33e3aec3a0f33f0b37e81a70609378612
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.

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.
