Transform matrix for transforming a surface to global_matrix is
calculated from
* ivi_layout_surface_properties
* ivi_layout_layer_properties
This patch pareares sub-method like following,
1/ calc_surface_to_global_matrix()
calc_transformation_matrix() is called twice with
ivi_layout_surface/layer_properties respectively.
2/ calc_transformation_matrix()
This calcurates matrix from orientation, source rectangle and
destination rectangle.
2-1/ To calculate rotation, fit centor of source rectangle to (0,0)
temporarily. This is moved back in 2-4.
2-2/ Apply rotation variant
2-3/ Apply scale variant
2-4/ Apply positioning variant, taking account into 2-1 temporary
positioning.

To refactor transform of ivi_layout_surface and ivi_layout_surface to be
more readable logical flow.
Remove following parts once,
* definition of weston_transform in ivi_layout_surface
* update_layer_orientation
* update_layer_position
* update_surface_position
* update_surface_orientation
* update_scale

if a controller calls ivi_layout_layer_create_with_demenstion with a ID
which is already created before, the API returns exist ivi_layer.
However addtionally, it shall count up ref count to destroy ivi_layer
when ref count is 0. The previous code will destroy ivi_layer
immediately even if the other code still refers ivi_layer.

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 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.

- 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.
