clients: a reference implementation of UI client how to use ivi-hmi-controller.

- introduces ivi-shell-user-interface.c

This is launched from hmi-controller by launch_hmi_client_process and
invoke a
client process.

The basic flow is as followed,
1/ process invoked
2/ read configuration from weston.ini.
3/ draw png file to surface according to configuration of weston.ini
4/ all parts of UI are ready. request "UI_ready" to draw UI.
5/ Enter event loop
6/ If a surface receives touch/pointer event, followings are invoked
according
   to type of event and surface
6-1/ If a surface to launch ivi_application receive touch up, it execs
     ivi-application configured in weston.ini.
6-2/ If a surface to switch layout mode receive touch up, it sends a
request,
     ivi_hmi_controller_switch_mode, to hmi-controller.
6-3/ If a surface to show workspace having launchers, it sends a
request,
     ivi_hmi_controller_home, to hmi-controller.
6-4/ If touch down events happens in workspace,
     ivi_hmi_controller_workspace_control is sent to slide workspace.
     When control finished, event:
ivi_hmi_controller_workspace_end_control
     is received.
