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.

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'.

remove old sensor service and implement SensorManager
on top of the new (native) SensorManger API.

This significantly re-works the native key dispatching code to
allow events to be pre-dispatched to the current IME before
being processed by native code. It introduces one new public
API, which must be called after retrieving an event if the app
wishes for it to be pre-dispatched.
Currently the native code will only do pre-dispatching of
system keys, to avoid significant overhead for gaming input.
This should be improved to be smarted, filtering for only
keys that the IME is interested in. Unfortunately IMEs don't
currently provide this information. :p

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.

in this commit:
- implemented the C stub
- implemented the binder interfaces involved
- implemented most of the C++ client side
missing:
- SensorManager cannot connect to the SensorServer yet
(because there is no SensorServer yet)

And also:
- APIs to show and hide the IME, and control its interaction with the app.
- APIs to tell the app when its window resizes and needs to be redrawn.
- API to tell the app the content rectangle of its window (to layout
around the IME or status bar).
There is still a problem with IME interaction -- we need a way for the
app to deliver events to the IME before it handles them, so that for
example the back key will close the IME instead of finishing the app.

Also other cleanup and fixes:
- We now properly set the default window format to 565.
- New APIs to set the window format and flags from native code.
- Tweaked glue for simpler handling of the "destroy" message.
- Um, other stuff.

This factors out the boiler-plate code from the sample
app to a common glue code that can be used for everyone
writing this style of app: a dedicated app thread that
takes care of waiting for events and processing them.
As part of doing this, ALooper has a new facility to allow
registration of fds that cause ALooper_pollOnce() to return
the fd that has data, allowing the app to drive the loop
without callbacks. Hopefully this makes some people feel better. :)
Also do some other cleanup of the ALooper API, plus some
actual documentation.

This allows us to avoid exposing the file descriptor of
the event queue; instead, you attach an event queue to
a looper. This will also should allow native apps to be
written without the need for a separate thread, by attaching
the event queue to the main thread's looper and scheduling
their own messages there.

Not yet hooked up to anything in the NDK, but requires renaming
the existing android_native_window_t type everywhere.

The native code now maintains a list of all keys that may use
default handling. If the app finishes one of these keys
without handling it, the key will be passed back off to Java
for default treatment.

Provides the basic infrastructure for a
NativeActivity's native code to get an object representing
its event stream that can be used to read input events.
Still work to do, probably some API changes, and reasonable
default key handling (so that for example back will still
work).
Change-Id: I6db891bc35dc9683181d7708eaed552b955a077e
Added more tests.
Fixed a regression in Vector.
Fixed bugs in pointer tracking.
Fixed a starvation issue in PollLoop when setting or removing callbacks.
Fixed a couple of policy nits.
Modified the internal representation of MotionEvent to be more
efficient and more consistent.
Added code to skip/cancel virtual key processing when there are multiple
pointers down. This helps to better disambiguate virtual key presses
from stray touches (such as cheek presses).

The old dispatch mechanism has been left in place and continues to
be used by default for now. To enable native input dispatch,
edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.
Includes part of the new input event NDK API. Some details TBD.
To wire up input dispatch, as the ViewRoot adds a window to the
window session it receives an InputChannel object as an output
argument. The InputChannel encapsulates the file descriptors for a
shared memory region and two pipe end-points. The ViewRoot then
provides the InputChannel to the InputQueue. Behind the
scenes, InputQueue simply attaches handlers to the native PollLoop object
that underlies the MessageQueue. This way MessageQueue doesn't need
to know anything about input dispatch per-se, it just exposes (in native
code) a PollLoop that other components can use to monitor file descriptor
state changes.
There can be zero or more targets for any given input event. Each
input target is specified by its input channel and some parameters
including flags, an X/Y coordinate offset, and the dispatch timeout.
An input target can request either synchronous dispatch (for foreground apps)
or asynchronous dispatch (fire-and-forget for wallpapers and "outside"
targets). Currently, finding the appropriate input targets for an event
requires a call back into the WindowManagerServer from native code.
In the future this will be refactored to avoid most of these callbacks
except as required to handle pending focus transitions.
End-to-end event dispatch mostly works!
To do: event injection, rate limiting, ANRs, testing, optimization, etc.

This is a rough sketch of the new pure-native API, which you can
use through a NativeActivity in your manifest (no Java code in
the .apk needed!).
Intentionally no docs yet, the API is still being seriously
messed with. But it works.
