The main idea is to make libweston users use the form
#include <libweston/libweston.h>
instead of the plain
#include <compositor.h>
which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.

This patch introduces ivi_layout_view data struct,
which is a wrapper of weston_view.
There is always only one ivi_layout_view for an
ivi_layout_surface and ivi_layout_layer pair.
A surface could have many views with different
geometry and transformations, so that a surface
can be shown on:
1. On many screens
2. On the same screen with different positions
The geometry of a view is modified, when properties of
its layer are changed through ivi_layout_interface.
Users of ivi_layout_interface does not have direct access
to ivi_layout_view structure.
v2 changes:
1. Use ivi_view_is_rendered function instead of
active member
2. Add descriptions to introduced members of
structs

If surface transitions are not removed when surface is being removed, it
can lead to crash later when transition will finish, as it will try to

link_layer's sole purpose is to link a surface to multiple layers, if
the surface should be shown in multiple layers. This can be only
achieved, if the surface has multiple weston_views with different
transformation matrices.
Current implementation assumes in many places that a ivi_surface has
only one weston_view. Therefore, a surface can be only shown on one
layer.
Although this (a surface on multiple layers) is a nice to have feature
for ivi-shell, it is not very crucial. In any case, it is not an easy

[Pekka: Line-wrapped commit message.]
It is only possible to remove a surface from the order.surface_list of a
layer, when ivi_layout_layer_set_render_order is called with an empty
array. Therefore, list of surfaces are cumulated if the API is called
many times with different list of surfaces.
Change how the flags are set:
- Introduce the dirty parameter for triggering the render order change.
- IVI_NOTIFICATION_REMOVE/ADD flags are set only at commit_layer_list.
Checking wl_list_empty() on a link offers no information: if it returns
true, wl_list_remove() is safe to do. If it returns false, you still do
not know if wl_list_remove() is safe; the link could be part of a list,
or the link could be "uninitialized" (e.g. just wl_list_remove()'d).
(From Pekka Paalanen's comment at
http://lists.freedesktop.org/archives/wayland-devel/2015-August/023987.html).
Calling wl_list_init just before wl_list_insert is redundant, because
the links of the list are not read before it is overwritten by
wl_list_insert.
Use assert to control if the ivilayer->order.surface_list is empty.

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.
