protocol: add interface ivi_application extension

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.

ivi-shell: add the shell plugin for In-Vehicle Infotainment system

In-Vehicle Infotainment system traditionally manages surfaces with global
identification. A protocol, ivi_application, supports such a feature by
implementing a request, ivi_application::surface_creation defined in
ivi_application.xml.

The ivi-shell explicitly loads ivi-layout.so and a module to add business
logic like how to layout surfaces by using ivi-layout APIs.

ivi-shell: add IVI layout APIs

API set of controlling properties of surface and layer which groups
surfaces. An unique ID whose type is integer is required to create
surface and layer. With the unique ID, surface and layer are identified
to control them. The API set consists of APIs to control properties of
surface and layers about followings,

- visibility.
- opacity.
- clipping (x,y,width,height).
- position and size of it to be displayed.
- orientation per 90 degree.
- add or remove surfaces to a layer.
- order of surfaces/layers in layer/screen to be displayed.
- commit to apply property changes.
- notifications of property change.

protocol: ivi hmi controller protocol to set up IVI style UI

This protocol realizes following features,
- UI ready
- changing modes; tiling, side by side, full_screen, and random
- Give control a surface; workspace to be controlled by using ivi layout APIs
- Display/undisplay a surface; home contains sevaral workspaces to launch
  application

ivi-shell: a reference implementation how to use ivi-layout internal APIs

The library is used to manage layout of surfaces/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
surfaces/layers by only a central component which decide where
surfaces/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 layer to group surfaces of background, panel,
  and buttons
- Next, a application layer to show application surfaces.
- Workspace background layer to show a surface of background image.
- Workspace layer to show launcher to launch application with icons.
  Paths to binary and icon are defined in weston.ini. The width of
  this layer is longer than the size of screen because a workspace
  has several pages and is controlled by motion of input.

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

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.
