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.

* changes:
update EGL headers to the latest
update GL ES stub libraries with the new GL ES headers
fix OpenGL ES extension headers from khronos
update the OpenGL ES headers to the latest
* changes:
Add a test item the turns on a bunch of extra icons.
Move the status bar icon list, hopefully for the last time.
Call into the notification manager when the panel is revealed.
Move status_bar_latest_event and LatestItemView into SystemUI.apk.
Start the status bar service based on a configuration option, instead of trampolining through a braodcast receiver.
Require the STATUS_BAR_SERVICE permission for something to be the status bar.
Handle errors inflating notifications (and their icons).
* changes:
dead code removal
Cap the number of notifications that a given package can post.
Move the usb mass storage notification & activity into SystemUI.apk.
Add some disabled logging and another test case for reapplying the notification views.
Surfaces can now be parcelized and sent to remote
processes. When a surface crosses a process
boundary, it looses its connection with the
current process and gets attached to the new one.
