compositor: introduce internal shell_interface

Browse Source 
We're able now to create shell_surfaces inside Weston. This makes possible the
glue needed between shell and xserver-launcher.

On the desktop-shell, it was split the protocol part from shell_surface
specific functions to make this possible.
