f67c53eee3 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.

5c1ed84a2d 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.

3c5d125ed7 Add new glue code for writing native apps.
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.

4036f7f2b4 Fix native input dispatch in the emulator.
Set a default orientation of ROTATION_0.
Added some more careful checks based on whether we have valid
absolute axis information from the driver.
Reset key repeating during configuration changes since the keyboard
device may have been removed.

50de30a523 Native input event dispatching.
Target identification is now fully native.
Fixed a couple of minor issues related to input injection.
Native input enabled by default, can be disabled by setting
WindowManagerPolicy.ENABLE_NATIVE_INPUT_DISPATCH to false.

51d45a710e More native input event dispatching.
Added ANRs handling.
Added event injection.
Fixed a NPE ActivityManagerServer writing ANRs to the drop box.
Fixed HOME key interception.
Fixed trackball reporting.
Fixed pointer rotation in landscape mode.

f4a4ec2063 Even more native input dispatch work in progress.
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).

54bc281639 More work in progress on native events.
Refactored the code to eliminate potential deadlocks due to re-entrant
calls from the policy into the dispatcher.  Also added some plumbing
that will be used to notify the framework about ANRs.

e839a589bf Native input dispatch rewrite work in progress.
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.
