protocol: add interface ivi_application extension

ivi_applicatoin extension creates ivi_surface objects tied
to a given wl_surface with a given id. The given id can be used in a
shell to identify which application is assigned to a wl_surface and
layout the surface wherever the shell wants. ivi_surface objects can
be used to receive status of wl_surface in the scenegraph of the
compositor.

+                ivi compositor. These ivi_ids are defined as unique in the system to identify
+                it inside of ivi compositor. The ivi compositor implements business logic how to
+                set properties of the surface with ivi_id according to status of the system.
+                E.g. a unique ID for Car Navigation application is used for implementing special
+                logic of the application about where it shall be located.
+		if a wl_surface which already has another role is set, the server regards this as
+		error and disconnects the client.
