> Implement TextureImageTransportSurface using texture mailbox
> 
> This has a couple of advantages:
> - allow tearing down and recreating the UI parent context without
> losing the renderer contexts
> - do not require a context to be able to generate textures when
> creating the GLSurfaceHandle
> - clearer ownership semantics that potentially allows for more
> robust and easier lost context handling/thumbnailing/etc., since a texture is at
> any given time owned by either: UI parent, mailbox, or
> TextureImageTransportSurface
> - simplify frontbuffer protection logic;
> the frontbuffer textures are now owned by RWHV where they are refcounted
> 
> The TextureImageTransportSurface informs RenderWidgetHostView of the
> mailbox names for the front- and backbuffer textures by
> associating them with a surface_handle (1 or 2) in the AcceleratedSurfaceNew message.
> During SwapBuffers() or PostSubBuffer() cycles, it then uses 
> produceTextureCHROMIUM() and consumeTextureCHROMIUM()
> to transfer ownership between renderer and browser compositor.
> 
> RWHV sends back the surface_handle of the buffer being returned with the Swap ACK
> (or 0 if no buffer is being returned in which case TextureImageTransportSurface will
> allocate a new texture - note that this could be used to 
> simply keep textures for thumbnailing).
