Modify the filters. filter_func now only updates a child interface using the father interface. Additionally, the user may provide two functions to a filter: get_nchildren returns the wanted number of children. If NULL, filter_arg is used. get_child_ops enables the programmer to specify each child's interface. If NULL, the father's interface is used.
