Inserts @widget into the child widget list of @parent.
It will be placed after @previous_sibling, or at the beginning if @previous_sibling is %NULL.
After calling this function, gtk_widget_get_prev_sibling(widget) will return @previous_sibling.
If @parent is already set as the parent widget of @widget, this function can also be used to reorder @widget in the child widget list of @parent.
This API is primarily meant for widget implementations; if you are just using a widget, you *must* use its own API for adding children.
