This change implements two heuristics.
1. When events are older than 10 seconds, they are dropped.
2. If the application is currently busy processing an event and
the user touches a window belonging to a different application
then we drop the currently queued events so the other application
can start processing the gesture immediately.
Note that the system takes care of synthesizing cancelation events
automatically for any events that it drops.
Added some new handle types to allow the native dispatcher to
indirectly refer to the WindowManager's window state and app window
token. This was done to enable the dispatcher to identify the
application to which each window belongs but it also eliminates
some lookup tables and linear searches through the window list
on each key press.

Usb.ACTION_USB_CAMERA_ATTACHED and Usb.ACTION_USB_CAMERA_DETACHED are sent
when cameras are connected and disconnected.
The data field of the intent contains a Uri for the camera in the Mtp content provider.

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

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.

The lights support is only needed by PowerManagerService and NotificationManagerService, so we do not need a Binder API for it.
Move backlight and notification light support to new LightsService class.
The camera flash is now handled directly by the camera HAL, so the flash Hardware service flash support is obsolete.
