Change the protocol from ivi-controller to ivi-wm
This patch is for master branch only. For using wayland-ivi-extension version 2.x, the wayland protocol in WindowManager is changed from ivi-controller to ivi-wm. NOTE: If using this patch, the modification for AGL/meta-agl which described in SPEC-1244 is necessary. Bug-AGL: SPEC-1244 Change-Id: I5489db202dfeec8f4626aee53bd1f86c145b95d9 Signed-off-by: Yuta Doi <yuta-d@witz-inc.co.jp>

-
- 1. create a wl_surface
- 2. create ivi_surface for the wl_surface
- 3. destroy the ivi_surface
- 4. create ivi_surface for the wl_surface (with the same or another ivi_id as before)

- surface_create will create a interface:ivi_surface with numeric ID; ivi_id in
- 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.
- The server regards following cases as protocol errors and disconnects the client.
- - wl_surface already has an nother role.
- - ivi_id is already assigned to an another wl_surface.
-
- If client destroys ivi_surface or wl_surface which is assigne to the ivi_surface,
- ivi_id which is assigned to the ivi_surface is free for reuse.
