As part of the new compositor architecture, AGL client apps shall be using the XDG shell instead of the deprecated ivi_application interface. This also makes calls to libWindowManager and libHomeScreen redundant.

Daniel Stone & Scott Murray shall co-ordinate to prepare changes which make these calls optional for clients, to make it possible to build the AGL tree with the new compositor. Once the new compositor is fully rolled out and the old architecture has been removed, the WM/HS integration can be fully removed from the clients.
