To get property changes of ivi_surface, callbacks can be registered.
However there was no API to remove a callback rather than remove all
callbacks by using surface_remove_notification.
surface_remove_notification_by_callback can do it.

The reason why the result is not output in the method is that it avoids
to have dependency on CAIRO. If user want to output it to file, user
shall link CAIRO on its controller.
ivi_layout_surface_get_size is also supported here because user needs
stride to call ivi_layout_surafce_dump.

This fixes the breakage caused by "ivi-shell: make ivi-layout.c as a
part of ivi-shell.so"
hmi-controller.c:
A reference implementation of controller module does not use the layout
functions directly. This get function pointers at controller_module_init
which called by ivi-shell.
ivi-layout-export.h:
Definition of interfaces in a struction: ivi_controller_interface.
function pointers are set at ivi-layout.c.
ivi-layout-private.h:
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
in other files.
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
- introduces ivi-layout-export.h, ivi-layout.[ch]
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.
