Mathias Agopian 4d9b822e2c get rid of ISurface
ISurface was only used to get the IGraphicBufferProducer from
a Layer. It's now replaced by a BBinder subclass / IBinder and
is only used as a handle to the surface, to both refer to it
and manage its life-time.

Also cleaned-up a bit the ISurfaceComposer interface and
"create layer" code path.
