9d4d6c101d Add the MIN_UNDEQUEUED_BUFFERS query to ANW.
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.

1b20cde313 Pass the IGraphicBufferAlloc to SurfaceTextureClient.
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.

c4d4aeab52 Implement SurfaceTexture frame-available callback.
This change implements the onFrameAvailable callback for the
SurfaceTexture java class.  It includes the C++ SurfaceTexture code as
well as the JNI and Java code to enable the callback.

9a78c90cd4 Fix remote GraphicBuffer allocation in SurfaceFlinger.
This change fixes a horrible hack that I did to allow application
processes to create GraphicBuffer objects by making a binder call to
SurfaceFlinger.  This change introduces a new binder interface
specifically for doing this, and does it in such a way that
SurfaceFlinger will maintain a reference to the buffers until the app is
done with them.

f238e28500 Implement crop & transform for SurfaceTexture.
This change adds support for the setCrop and setTransform methods of the
SurfaceTexture C++ class.  The crop and transform for the current
texture will be accessed by applications as a single texture coordinate
transform matrix.

67eedd74ab Fix a bug in SurfaceTexture::setBufferCount.
We need to reset mCurrentTexture and mLastQueued in setBufferCount
because it frees all of the buffers associated with the buffer slots.

8ba32fade1 Add the SurfaceTexture C++ implementation.
This change adds the C++ implementation of SurfaceTexture and related
classes. The goal of this is for a SurfaceTexture to be passed to
camera service or Stagefright in place of a Surface to allow camera
preview or decoded video frames to be streamed to an OpenGL ES texture
that an application can use.
