[E-devel] [Patch][Elementary] Patch for elm_win to fix the focus chain issue in case of a widget added as a normal sub-object, not a resizable object

[Kim S. <kim...@gm...>]

Current Issue:
   Currently when we add a widget to window as a sub-object, e.g.
elm_notify_add(win) which internally calls elm_widget_sub_object_add
then the focus chain using <TAB> includes only
   the first focusable subitem of the widget, not all.
   Whereas with elm_win_resize_object_add, it works fine and cycles to
all focusable sub-items of the widget.

Reason:
   The reason is that we are appending sub-object to the list in
elm_win which is used for focus chain, only in case of
elm_win_resize_object_add.

Change Description:
   Added a new API: EAPI Eina_List
*elm_widget_sub_object_list_get(const Evas_Object *obj);
   This API returns the list of sub-objects of an elementary widget
(sd->subobjs) where sd is Smart_Data pointer obtainted using
elm_widget_smart_data_get(obj).
   We have used this API in elm_win for focus_next_hook implementation.
