1. Single finger tap performs a click.
2. Single finger movement moves the pointer (hovers).
3. Button press plus movement performs click or drag.
While dragging, the pointer follows the finger that is moving
fastest. This is important if there are additional fingers
down on the touch pad for the purpose of applying force
to an integrated button underneath.
4. Two fingers near each other moving in the same direction
are coalesced as a swipe gesture under the pointer.
5. Two or more fingers moving in arbitrary directions are
transformed into touches in the vicinity of the pointer.
This makes scale/zoom and rotate gestures possible.
Added a native VelocityTracker implementation to enable intelligent
switching of the active pointer during drags.

This change makes SurfaceFlinger treat layers for which the active
buffer has the GRALLOC_USAGE_PROTECTED bit set as if they have the
'secure' flag set.

Bug: 4081304
Associate each motion axis with the source from which it comes.
It is possible for multiple sources of the same device to define
the same axis. This fixes new API that was introduced in MR1.
(Bug: 4066146)
Fixed a bug that might cause a segfault when using a trackball.
Only fade out the mouse pointer when touching the touch screen,
ignore other touch pads.
Changed the plural "sources" to "source" in several places in
the InputReader where we intend to refer to a particular source
rather than to a combination of sources.
Improved the batching code to support batching events from different
sources of the same device in parallel. (Bug: 3391564)

This change adds a new 'method' to the ANativeWindow interface to check
whether buffers queued to the window will be sent directly to the system
window compositor.

Ensure that the joystick can always reach -1.0, 0.0 and 1.0 positions
even when noise filtering is applied. (Bug: 3514510)
Add support for a few more standard axes.
Add additional mapping modes for axes.
Some axes are inverted from standard interpretation
or are actually intended to be split into two distict axes
such as left/right trigger controls or accelerator/brake.
Add key layout file for a G25 racing wheel and XBox 360 controller
to tweak behavior. They work fine without them but the axis mappings
are not ideal.

Added some plumbing to enable the policy to intercept motion
events when the screen is off to handle wakeup if needed.
Added a basic concept of an external device to limit the scope
of the wakeup policy to external devices only. The wakeup policy
for internal devices should be based on explicit rules such as
policy flags in key layout files.
Moved isTouchEvent to native.
Ensure the dispatcher sends the right event type to userActivity
for non-touch pointer events like HOVER_MOVE and SCROLL.

Fades out the mouse pointer:
- after 15 seconds of inactivity normally
- after 3 seconds of inactivity in lights out mode
- after a non-modifier key down
- after a touch down
Extended the native Looper to support enqueuing time delayed
messages. This is used by the PointerController to control
pointer fade timing.

This change adds a new query to ANativeWindow for getting the minimum
number of buffers that must be left un-dequeued during the steady-state
operation of the ANativeWindow.

This change adds a null pointer check before dereferencing buffers in
a Surface list of known GraphicBuffer objects. If not all the buffers
have been dequeued before this list can legitimately contain NULL
entries.

some of the conversion operators were not using the proper
pointer type when calling incStrong/decStrong, usually it
has no bad consequences, but for some implementation
of the ref-counted object it could lead to recording the wrong
owner id.

First slipt sp<> out of RefBase into StrongPointer.h so it can be reused
more easily and to make it clear that it doesn't require RefBase.
Note: the rest of the change only affects the system when DEBUG_REFS is enabled.
The main problem we fix here is that the owner id associated with each
reference could get out of date when a sp<> or wp<> was moved, for
instance when they're used in a Vector< >.
We fix this issue by calling into RefBase::moveReferences from
a template specialization for sp<TYPE> and wp<TYPE> of the
type helpers. RefBase::moveReferences() has then a chance to
update the owner ids.
There is a little bit of trickery to implement this generically in
RefBase, where we need to use a templatized functor that can turn
a sp<TYPE>* casted to a void* into a RefBase*.
Introduced a new debug option DEBUG_REFS_FATAL_SANITY_CHECKS
currently set to 0 by default as there seem to be an issue
with sp<ANativeWindow> which trips the sanity checks.

Added support for tracking the mouse position even when the mouse button
is not pressed. To avoid confusing existing applications, mouse movements
are reported using the new ACTION_HOVER_MOVE action when the mouse button
is not pressed.
Added some more plumbing for the scroll wheel axes. The values are
reported to Views but they are not yet handled by the framework.
Change-Id: I1706be850d25cf34e5adf880bbed5cc3265cf4b1
Added API on InputDevice to query the set of axes available.
Added API on KeyEvent and MotionEvent to convert keycodes and axes
to symbolic name strings for diagnostic purposes.
Added API on KeyEvent to query if a given key code is a gamepad button.
Added a new "axis" element to key layout files to specify the
mapping between raw absolute axis values and motion axis ids.
Expanded the axis bitfield to 64bits to allow for future growth.
Modified the Makefile for keyboard prebuilts to run the keymap
validation tool during the build.
Added layouts for two game controllers.
Added default actions for game pad button keys.
Added more tests.
Fixed a bunch of bugs.

HAVE_ANDROID_OS was defined as "1" for targets, but never defined as "0"
for non-targets. Changing them to #ifdef should be safe and matches
all the other uses of HAVE_ANDROID_OS throughout the system.

This change makes it possible to extend the set of axes that
are reported in MotionEvents by defining new axis constants.
The MotionEvent object is now backed by its C++ counterpart
to avoid having to maintain multiple representations of the
same data.

This change passes a reference to the IGraphicBufferAlloc binder object
to SurfaceTextureClient objects. When STC objects are created they
query their associated ISurfaceTexture object for the
IGraphicBufferAlloc that the SurfaceTexture uses to allocate buffers.
Having the SurfaceTextureClient hold this reference prevents the
GraphicBufferAlloc in SurfaceFlinger from freeing the allocated buffers
before the SurfaceTextureClient is done with them.

This is a temporary WAR for the case where dequeueBuffer is called when
all the buffers owned by a SurfaceTexture are not available - either
they're the current texture buffer or the next one. Currently, an error
is returned in that case, and this change just prevents that error from
being logged. In the future this will be fixed to not return an error
in that case.

A previously exited Thread object refuses to run again, if the
thread-id of the caller, conincides with the thread-id it previously
used in the worker thread. Hence reset the previously used worker
thread-id to -1 when it exits.
