[PATCH weston 7/8] shell: export shell_surface internal field via shell_interface

[Tiago Vignatti]

xserver submodule lacks visibility on shell_surface internals. In order to get
shell_surface->weston_surface->geometries for the commit coming next, this is
being introduced. It's a hack really.

Another solution could be xserver access directly shell, but both are loaded
modules without symbols being shared.

We probably need shell_surface on global scope soon.
