  Remove obsolete Renderbuffer types.
  
  RenderbufferProxySet and FramebufferTextureBindingPointer aren't
  necessary any more with our refactored renderbuffer classes and
  ownership of attachments by the Framebuffer.
  
  We can also consolidate the FramebufferAttachment and implementation
  to a single class, and no longer need to store ref counted objects
  in the Framebuffer class directly.
