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.

Modify native ALooper to take an explicit ident.
The ALooper API now uses an explicit "identifier" for the integer
that is returned rather than implicitly using the fd. This allows
the APIs that had the fd to be a little more sane.

This was causing stack stitching problems where a one-way call with
violations followed by a two-way call without violations was getting
the previous one-way call's violation stack stitched on to the second
caller's stack.
The solution is a little more indirect than I would've liked
(preserving the binder's onTransact flags until enforceInterface) but
was seemingly necessary to work without changing the AIDL compiler.
It should also be sufficiently cheap, since no new calls to
thread-local IPCThreadState lookups were required. The additional
work is just same-thread getter/setters on the existing
IPCThreadState.

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.

fix [2931513] Add support for setting the orientation of an ANativeWindow
This change makes the camera HAL interface take an ANativeWindow interface from
which all the camera preview buffers will be allocated. The framework code
running in application processes now passes a Surface object rather than an
ISurface to the camera server via Binder when setting the preview surface. The
camera server then forwards that Surface object (which implements the
ANativeWindow interface) to the camera HAL, which uses it to communicate with
SurfaceFlinger to allocate the camera preview buffers.

Fix some input device mapping bugs with certain drivers.
On single-touch devices, pointer up/down is signalled by a BTN_TOUCH
key event. Previously we handled BTN_TOUCH immediately but some drivers
may produce the sequence BTN_TOUCH, ABS_X, ABS_Y, SYN_REPORT on pointer down
which caused us to emit a bad initial pointer down location.
Now we wait for SYN_REPORT before reporting the up or down.
On multi-touch devices, pointer up can be signalled by as little as
the sequence SYN_MT_REPORT, SYN_REPORT. This change ensures that we
handle this case.
Added support for reading ABS_MT_PRESSURE when available.
Corrected mapping of touchMajor/touchMinor on single touch devices.
Minor code cleanup.

Fix possible race conditions during channel unregistration.
Sometimes the wrong fd was accessed when the device was addressed
by device id.
The earlier implementation assumed that two arrays were in sync
but one of them was compacted when devices were removed. Instead
of that dependency the device now keeps track of it's file descriptor.

Previously, the input dispatcher assumed that the input channel's
receive pipe file descriptor was a sufficiently unique identifier for
looking up input channels in its various tables. However, it can happen
that an input channel is disposed and then a new input channel is
immediately created that reuses the same file descriptor. Ordinarily
this is not a problem, however there is a small opportunity for a race
to arise in InputQueue.
When InputQueue receives an input event from the dispatcher, it
generates a finishedToken that encodes the channel's receive pipe fd,
and a sequence number. The finishedToken is used by the ViewRoot
as a handle for the event so that it can tell the InputQueue when
the event has finished being processed.
Here is the race:
1. InputQueue receives an input event, assigns a new finishedToken.
2. ViewRoot begins processing the input event.
3. During processing, ViewRoot unregisters the InputChannel.
4. A new InputChannel is created and is registered with the Input Queue.
This InputChannel happens to have the same receive pipe fd as
the one previously registered.
5. ViewRoot tells the InputQueue that it has finished processing the
input event, passing along the original finishedToken.
6. InputQueue throws an exception because the finishedToken's receive
pipe fd is registered but the sequence number is incorrect so it
assumes that the client has called finish spuriously.
The fix is to include a unique connection id within the finishedToken so
that the InputQueue can accurately confirm that the token belongs to
the currently registered InputChannel rather than to an old one that
happened to have the same receive pipe fd. When it notices this, it
ignores the spurious finish.
I've also made a couple of other small changes to avoid similar races
elsewhere.
This patch set also includes a fix to synthesize a finished signal
when the input channel is unregistered on the client side to
help keep the server and client in sync.

Add support for the PointerLocation overlay.
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).

Fixed a bug in TouchInputMapper where it was not correctly copying
