Tran Ba Khang(MS/EMC31-XC) 91750cdbd4 hmi-controller: switch to listening the shell destroy signal
Listening the shell destroy instead of compositor destroy signal.
This show how to in case the controller depends on shell resource.
The order destroying had changed in this commit, the controller
is destroyed first now

/**
* A reference implementation how to use ivi-layout APIs in order to manage
* layout of ivi_surfaces/ivi_layers. Layout change is triggered by
* ivi-hmi-controller protocol, ivi-hmi-controller.xml. A reference how to
* use the protocol, see hmi-controller-homescreen.
*
* In-Vehicle Infotainment system usually manage properties of
* ivi_surfaces/ivi_layers by only a central component which decide where
* ivi_surfaces/ivi_layers shall be. This reference show examples to
* implement the central component as a module of weston.
*
* Default Scene graph of UI is defined in hmi_controller_create. It
* consists of
* - In the bottom, a base ivi_layer to group ivi_surfaces of background,
* panel, and buttons
* - Next, an application ivi_layer to show application ivi_surfaces.
* - Workspace background ivi_layer to show a ivi_surface of background image.
* - Workspace ivi_layer to show launcher to launch application with icons.
* Paths to binary and icon are defined in weston.ini. The width of this
* ivi_layer is longer than the size of ivi_screen because a workspace has
* several pages and is controlled by motion of input.
*
* TODO: animation method shall be refined
* TODO: support fade-in when UI is ready
