API addition: The timestamps are represented as nanoseconds from some
arbitrary time point. Like the SurfaceTexture transform matrix, the
timestamp retrieved by getTimestamp is for the last frame sent to the
GL texture using updateTexImage().
Camera HAL change: Expect vendors to set these timestamps using
native_window_set_buffers_timestamp(). For now, they are
autogenerated by SurfaceTextureClient if set_buffers_timestamp() is
never called, but such timing is likely not accurate enough to pass a
CTS test.

This change fixes the transform matrix computation in SurfaceTexture
when a crop rectangle is specified by the image producer. It also adds
a test for this case as well as a basic test for the uncropped case.

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 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 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.

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.

This change fixes a bug that allowed the most recently queued buffer to
be returned by dequeueBuffer. At the next updateTexImage call, the
dequeued buffer would be set as the contents of the texture even though
the client could be writing to it.

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.

We need to reset mCurrentTexture and mLastQueued in setBufferCount
because it frees all of the buffers associated with the buffer slots.

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.
