the first time a surface was connected, the values returned
by query NATIVE_WINDOW_DEFAULT_{WIDTH|HEIGHT} and
NATIVE_WINDOW_TRANSFORM_HINT were wrong until a call
to queueBuffer was performed.

This change adds the 'abandon' method to the SurfaceTexture C++ class.
This method may be used to put the SurfaceTexture in an abandoned state,
causing all ISurfaceTexture methods to fail.

This change removes the SurfaceTexture::getAllocator method, as it's no
longer needed. Proper refcounting of the Gralloc buffers is now handled
by the IGraphicBufferAlloc binder marshalling code.

This change makes the ANativeWindow connect and disconnect calls result
in an IPC to the SurfaceTexture object. This will allow us to prevent
multiple simultaneous connections from different processes.

This change the binder protocol between SurfaceTextureClient
and SurfaceTexture. dequeueBuffer() now takes the requested
parameters for the buffer. SurfaceTexture decides if the
buffer needs to be reallocated and does the allocation
if needed. In that case it returns BUFFER_NEEDS_REALLOCATION
to tell SurfaceTextureClient that it needs to call
requestBuffer (which all parameters have been removed) to
acquire a pointer to the buffer.
dequeueBuffer and requestBuffer could be folded into a single
IPC call, but we chose to optimize the case where buffers are
not created and avoid some complexity in the marshalling code.

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.

Change-Id: Ife131a0c2a826ac27342e11b8a6c42ff49e1bea7
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 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.
