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>
