Provide Weston IVI-Shell, run it on demand

Weston IVI-Shell provides a shell plugin for Weston,
mapping the GENIVI API (http://www.genivi.org) for
In-Vehicle Infotainment.

This is a code backport from Weston 1.9.0 "release".

This patch makes sure that Weston IVI-Shell always gets
built ; it will not be started, however, unless the builder
specifies the following in his "conf/local.conf" file :

IMAGE_INSTALL_append = " \
    weston-ivi-shell-config \
    "

or manually overwrites the "/etc/xdg/weston/weston.ini"
file with a correct one.

+Subject: [PATCH] Backport IVI-Shell from Weston 1.9.0 to 1.5.0
+
+IVI-Shell is the alternative Weston shell implementing the
+eponymous protocol, and supported in client toolkits such
+as EFL, Qt...
+
+We backport only the necessary, without touching the core
+compositor if possible (was only necessary for surface
+copying logic which had a patch in Tizen IVI).

++ * 5-1/ If a surface to launch ivi_application receive touch up, it execs

++ * 5-2/ If a surface to switch layout mode receive touch up, it sends a request,
++ *	  ivi_hmi_controller_switch_mode, to hmi-controller.
++ * 5-3/ If a surface to show workspace having launchers, it sends a request,
++ *	  ivi_hmi_controller_home, to hmi-controller.
++ * 5-4/ If touch down events happens in workspace,

++ * In-Vehicle Infotainment system usually manage properties of

++ *
++ * 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, a 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

++/**
++ * The ivi-layout library supports 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.
++ *
++ * Management of surfaces and layers grouping these surfaces are common
++ * way in In-Vehicle Infotainment system, which integrate several domains
++ * in one system. A layer is allocated to a domain in order to control
++ * application surfaces grouped to the layer all together.
++ *
++ * This API and ABI follow following specifications.

++/**
++ * Implementation of ivi-layout library. The actual view on ivi_screen is
++ * not updated till calling ivi_layout_commit_changes. A overview from
++ * calling API for updating properties of ivi_surface/ivi_layer to asking
++ * compositor to compose them by using weston_compositor_schedule_repaint,
++ * 0/ initialize this library by ivi_layout_init_with_compositor
++ *    with (struct weston_compositor *ec) from ivi-shell.
++ * 1/ When a API for updating properties of ivi_surface/ivi_layer, it updates
++ *    pending prop of ivi_surface/ivi_layer/ivi_screen which are structure to
++ *    store properties.
++ * 2/ Before calling commitChanges, in case of calling a API to get a property,
++ *    return current property, not pending property.
++ * 3/ At the timing of calling ivi_layout_commitChanges, pending properties
++ *    are applied to properties.
++ *
++ *    *) ivi_layout_commitChanges is also called by transition animation
++ *    per each frame. See ivi-layout-transition.c in details. Transition
++ *    animation interpolates frames between previous properties of ivi_surface
++ *    and new ones.
++ *    For example, when a property of ivi_surface is changed from invisibility
++ *    to visibility, it behaves like fade-in. When ivi_layout_commitChange is
++ *    called during transition animation, it cancels the transition and
++ *    re-start transition to new properties from current properties of final
++ *    frame just before the the cancellation.
++ *
++ * 4/ According properties, set transformation by using weston_matrix and
++ *    weston_view per ivi_surfaces and ivi_layers in while loop.
++ * 5/ Set damage and trigger transform by using weston_view_geometry_dirty.
++ * 6/ Notify update of properties.
++ * 7/ Trigger composition by weston_compositor_schedule_repaint.
