[PATCH weston-ivi-shell v4 3/9] ivi-shell supports a type of shell for In-Vehicle Infotainment system.

In-Vehicle Infotainment system traditionally manages surfaces with global
identification. A protocol, ivi_application, supports such a feature by
implementing a request, ivi_application::surface_creation defined in
ivi_application.xml. Additionally, it initialize a library, weston-layout,
to manage properties of surfaces and group surfaces in layer. In detail,
refer library, weston_layout.

Changes for v2:
- apply review comments of mailing list.
- squash update of Makefile into this patch.
- move this patch after patch of weston-layout.
- support inherit propoerties of id_surface when client attaches another
wl_surface with id_surface after destroying ivi_surface once.
Changes for v3:
- squash internal method, configure, to ivi_shell_surface_configure.
Changes for v4:
- nothing. Version number aligned to the first patch
