Added a new PointerIcon API (hidden for now) for loading
pointer icons.
Fixed a starvation problem in the native Looper's sendMessage
implementation which caused new messages to be posted ahead
of old messages sent with sendMessageDelayed.
Redesigned the touch pad gestures to be defined in terms of
more fluid finger / spot movements. The objective is to reinforce
the natural mapping between fingers and spots which means there
must not be any discontinuities in spot motion relative to
the fingers.
Removed the SpotController stub and folded its responsibilities
into PointerController.

Some drivers report individual finger updates one at a time
instead of all at once. When 10 fingers are down, this can
cause the framework to have to handle 10 times as many events
each with 10 times as much data. Applications like
PointerLocation would get significantly bogged down by all
of the redundant samples.
This change coalesces samples that are closely spaced in time,
before they are dispatched, as part of the motion event batching
protocol.
Increased the size of the InputChannel shared memory buffer so
that applications can catch up faster if they accumulate a
backlog of samples.

The SurfaceTextureSyncModeWaitRetire test was disabled. It is failing
because of the synchronization hacks that were added to SurfaceTexture
to work around bugs in vendor device drivers.

This change fixes the MIN_UNDEQUEUED_BUFFERS error check in
dequeueBuffer. The check should only be performed if a buffer has been
queued since the last time the buffer count was changed by the client.
The check must be applied conditionally because video decoders require
all the bufferes to be dequeued and registered before beginning the
decode.

This change fixes up some stale comments, member variable names, log

* commit 'c9cd2387b6938a6fbefc731d2177902266f2a130':
Fix a race that could cause GL commands to be executed from the wrong thread.
RefBase subclasses can now decide how they want to be destroyed.
Fix a race in SurfaceFlinger that could cause layers to be leaked forever.
Fix a race-condtion in SurfaceFlinger that could lead to a crash.
Added a timeout mechanism to EventHub and InputReader so that
InputMappers can request timeouts to perform delayed processing of
input when needed.

Replaced VelocityTracker with a faster and more accurate
native implementation. This avoids the duplicate maintenance
overhead of having two implementations.
The new algorithm requires that the sample duration be at least
10ms in order to contribute to the velocity calculation. This
ensures that the velocity is not severely overestimated when
samples arrive in bursts.
The new algorithm computes the exponentially weighted moving
average using weights based on the relative duration of successive
sample periods.
The new algorithm is also more careful about how it handles
individual pointers going down or up and their effects on the
collected movement traces. The intent is to preserve the last
known velocity of pointers as they go up while also ensuring
that other motion samples do not count twice in that case.

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.

In resources.arsc files, a resource is represented by a specification
block and one or more value blocks. In rare cases, a resource name
is also given a new resource ID, a specification block and no values
blocks. This commit ensures idmap generation does not fail if such an
entry is encountered.

Adds a new camera parameter for locking auto-white balance to its
current value. Also adds a function for checking if auto-white balance
lock is supported by the current platform. Lock semantics match that
of the auto-exposure lock.
Hidden for now.

Added the concept of pointer properties in a MotionEvent.
This is currently used to track the pointer tool type to enable
applications to distinguish finger touches from a stylus.
Button states are also reported to application as part of touch events.
There are no new actions for detecting changes in button states.
The application should instead query the button state from the
MotionEvent and take appropriate action as needed.
A good time to check the button state is on ACTION_DOWN.
As a side-effect, applications that do not support multiple buttons
will treat primary, secondary and tertiary buttons identically
for all touch events.
The back button on the mouse is mapped to KEYCODE_BACK
and the forward button is mapped to KEYCODE_FORWARD.
Added basic plumbing for the secondary mouse button to invoke
the context menu, particularly in lists.
Added clamp and split methods on MotionEvent to take care of
common filtering operations so we don't have them scattered
in multiple places across the framework.

You can now specify resource configuration variants "wNNNdp"
and "hNNNdp". These are the minimum screen width/height in "dp"
units. This allows you to do things like have your app adjust
its layout based only on the about of horizontal space available.
This introduces a new configuration change flag for screen size.
Note that this configuration change happens each time the orientation
changes. Applications often say they handle the orientation change
to avoid being restarted at a screen rotation, and this will now
cause them to be restarted. To address this, we assume the app can
handle this new config change if its target SDK version is < ICS.

'tar' supports only 100-character paths; 'ustar' supports only
155+100 character prefix + paths; neither supports files larger
than about 8 gigabytes. We now use the POSIX.1-2001 'pax'
extended tar format for those files in the backup stream that
are too large or have too-long paths for the 'ustar' format.
