This fixes the breakage caused by "ivi-shell: make ivi-layout.c as a

A reference implementation of controller module does not use the layout
functions directly. This get function pointers at controller_module_init

Definition of some interfaces are remove bucause it is implemented in
ivi-layout.c and set it as function pointer. Several interfaces are kept
here because they are implemented in ivi-layout.c/transition.c but used

ivi-layout-transition.c:
remove WL_EXPORT because export is not needed anymore.
remove unnesesary unsed method.
ivi-shell.c:
call controller_module_init of hmi-controller to init it and set
function pointers. If the interface_version is equal or
greater than what hmi_controller was built with, things are pass.
If the interface_version is smaller than what the controller expects,
it has to fail because it cannot work. This is followed the manner,
- never remove a function pointer
- never modify an existing function signature
- additions are allowed at the end of struct ivi_controller_interface
- all function pointers must always be populated and working in
ivi-shell.so (ivi-layout.c etc.)

ivi-layout.so is separately built and loaded by using dlopen with
RTLD_GLOBAL. This was because these apis defined in ivi-layout.so shall
be used by ivi-modules; e.g. hmi-controller. This shall be improved that
a struct ivi_layout_api contains the whole exported API as function
pointers to be exposed as module_init.
This patch alone builds, but loading controller modules at runtime
failes. This failure will be fixed by following patches.

Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?

When printing out logs from Weston's actions, mainly for debugging, it
can be very difficult to identify the different surfaces. Inspecting
the configure function pointer is not useful, as the configure functions
may live in modules.
Add vfunc get_label to weston_surface, which will produce a short,
human-readable description of the surface, which allows identifying it
better, rather than just looking at the surface size, for instance.
Set the label function from most parts of Weston, to identify cursors and
drag icons, and panels, backgrounds, screensavers and lock surfaces, and
the desktop shell's application surfaces.
v2: renamed 'description' to 'label', so we get
weston_surface_set_label_func().

- hmi-controller.so
- introduces hmi-controller.so
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 ivi-shell-user-interface.c.
In-Vehicle Infotainment system usually manages properties of
surfaces/layers by only a central component which decide where
surfaces/layers shall be. This is differenct use case from desktop
style; each application can request property of its window via xdg-shell
protocol, like fullscreen and set its to top level. In-Vehicle
Infortainment system doesn't allow each application to chagen them from
its application because of safty reasons. The concept of layer is
simillar with a use case of cursor layer of Destop. For In-Vehicle
Infortainment system, it is extended to all applications. For example,
rearview camera application is assigned to a layer to group several
surfaces, e.g. captured image and drawing lines separately. Central
manaegr can control property of the layer of rearview camera.
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.

- introduces ivi-application.xml
Many applications in an IVI-system are special single-purpose
applications that have a very specific role in the whole IVI UI, for
example a rear camera, speedometer, map, etc. The IVI system vendor
specifies what these are and how they integrate into the UI. They also
vary between particular IVI systems. This is why we use (system-)global,
unique, pre-determined ID numbers to tell what wl_surface is which
application, instead of writing specific shell requests for each one.
Using ID numbers allows vendors to easily invent new component
applications without extending or breaking the actual Wayland protocol.
In IVI-systems, the ID is a standard concept already used in several
APIs, with a vendor-specified global definition of ID assignments.

When ending a drag in the window the cursor will be wrong until the mouse
is moved again. This is because the item being dragged isn't added
until after the enter event.
Also, when picking up an item while moving the mouse the cursor can switch
back to a non-drag cursor before the drag begins. This is because of a
slight delay between button click and drag start.
Finally picking up or dropping an item under a second pointer could cause
that pointer to have the wrong cursor.
