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.

- Squash Makefile.
- Add description to ivi_surface:destroy.
- Update description of ivi_application:surface_create.
Changes for v4:

- Add clear discripton what client shall do if it encounters warning in ivi_surface
::warning.
- Add decription what happens when client tries to tie a wl_surface to multiple
ivi_surfaces.
Changes for v5:
- apply review comments from mailing list

+ 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
