[PATCH 1/7] shell: Add xdg-shell support to weston.

Fri Jul 19 12:42:43 PDT 2013
From: Rafael Antognolli <rafael.antognolli at intel.com>
Implement the xdg-shell inside xdg-surface.c, and make it a compile time
option to wl-shell. If enabled, weston will start using it instead of wl-shell.
It's basically a copy of wl-shell so far, and it generates the protocol
headers with wayland_scanner, from an installed xdg_surface.xml protocol
file.
