This change also removes the use of SoftReferences for View's
drawing cache.
A bitmap now creates a PhantomReference enqueued in a reference
queue provided by the new Finalizers class. This queue is polled
from a thread started after forking zygote. That thread is in charge
of clearing the references after GC runs and of calling reclaim()
on them. The reclaim() method is now how finalizers are run.
Note that a PhantomReference cannot be kept in the instance it
refers to, which is why they are kept in a separate List.

The makefile variable USE_OPENGL_RENDERER must be set to true to compile
libhwui and the related code in the JNI layer.
This change also removes obsolete APIs from Canvas that must not be used
and would be confusing if left in. These APIs were remnants of our first
attempt at an OpenGL renderer for the view hierarchy and had not been
taken out before Android 1.0 was released.

Since orientation sensing has been an issue for numerous users, I
decided a spend a little time experimenting with some possible
improvements. I've settled on a couple major changes:
* Perform all lowpass filtering in spherical coordinates, not
cartesian. Since the rotations are what we're really concerned
with, this makes more sense and gives more consistent results.
* Introduce a system of tracking "distrust" in the current data, based
on external acceleration and on tilt. The basic idea is after a
signal of unreliable data -- repeated acceleration or
nearly-horizontal tilt -- we wait for things to "stabilize" for some
number of ticks before we start trusting the data again. This is an
extension of the basic lowpass filtering. One simple example is
after the phone is picked up off a table, we ignore the first few
readings. Another example is while the phone is under external
acceleration for a while (i.e. in a car mount on a rough road), if a
single "good" reading comes in, we distrust it, under the assumption
that it was probably just a lucky reading (i.e. the magnitude
happened to be close to that of gravity by chance).
These changes have allowed me to relax other constraints, such as the
filtering time constants, the maximum deviation from gravity, and the
max tilt before we start distrusting data.
The net effect is that orientation changes happen more quickly and can
happen under a wider variety of conditions, but false changes due to
tilt and acceleration are still avoided well. I think the improvement
is subtle, but it's the best I've come up with in my limited time.
I've also included some refactoring and additonal comments to try and
further clarify the (somewhat twisted) logic.

Rendering is implementing by rasterizing the paths into A8 textures.
This cna be extremely inefficient if the path changes often.

Hardware acceleration can now be enabled/disabled locally on each activity
declared in the manifest. It can also be enabled/disabled directly on a
window through the WindowManager.LayoutParams.

Improved PointerLocation tool to use VelocityTracker more efficiently
and correctly when multiple pointers are down.
Fixed a bug in TouchInputMapper where it was not correctly copying
the id to index map in the last touch data. This could cause strange
behavior on secondary pointer up events.
Also added finished callback pooling in InputQueue.

With this change, Skia shaders can easily be applied to any mesh. This change also
supports ComposeShader. For instance, this can be used to blend a gradient and a
bitmap togehter and paint a string of text with the result.

Context menu entries have been moved to a contextual mode in the action bar.
Change Input Method has been removed and *should be added to the system bar instead*.
Add word to dictionnary has also been removed and should now be done using the suggestioni
bar "tap on word to add" feature.

Merge commit '9795a25da060f9a7df87da8ab43fb1086d4322a5'
* commit '9795a25da060f9a7df87da8ab43fb1086d4322a5':
Refactor input reader to support new device types more easily.
Refactored the input reader so that each raw input protocol is handled
by a separate subclass of the new InputMapper type. This way, behaviors
pertaining to keyboard, trackballs, touchscreens, switches and other
devices are clearly distinguished for improved maintainability.
Added partial support for describing capabilities of input devices
(incomplete and untested for now, will be fleshed out in later commits).
Simplified EventHub interface somewhat since InputReader is taking over
more of the work.
Cleaned up some of the interactions between InputManager and
WindowManagerService related to reading input state.
Fixed swiping finger from screen edge into display area.
Added logging of device information to 'dumpsys window'.

With this change, all the vertex and fragment shaders used by the GL
renderer are now generated based on a program description supplied
by the caller. This allows the renderer to generate a large number
of shaders without having to write all the possible combinations by
hand. The generated shaders are stored in a program cache.

ContextualMode renamed to ActionMode. Adds a reference to the action
bar and reduces confusion around things named "Context".

The LinearGradient class keeps a copy of the various parameters that
define the gradient. The copies are native arrays to avoid copying
Java arrays on every draw call. The gradient code path is implemented
until OpenGLRenderer::drawRect() (see TODO.) The actual gradient
implementation will be added in a latter change.

Add dumpsys integration for the native input dispatcher.
Add some InputDevice API stubs.
Add an appendFormat helper method to String8 for printf style
string formatting mainly for debugging purposes.
Use generic ArrayList<WindowState> everywhere in WindowManagerService
to eliminate unnecessary casts all over.

Added several new coordinate values to MotionEvents to capture
touch major/minor area, tool major/minor area and orientation.
Renamed NDK input constants per convention.
Added InputDevice class in Java which will eventually provide
useful information about available input devices.
Added APIs for manufacturing new MotionEvent objects with multiple
pointers and all necessary coordinate data.
Fixed a bug in the input dispatcher where it could get stuck with
a pointer down forever.
Fixed a bug in the WindowManager where the input window list could
end up containing stale removed windows.
Fixed a bug in the WindowManager where the input channel was being
removed only after the final animation transition had taken place
which caused spurious WINDOW DIED log messages to be printed.
