This is a fundamental change of an original (1999) concept of route processing inside BIRD. During import/export, there was a temporary ea_list created which was to be used instead of the another one inside the route itself. This led to some confusion, quirks, and strange filter code that handled extended route attributes. Dropping it now. The protocol interface has changed in an uniform way -- the `struct ea_list *attrs` argument has been removed from store_tmp_attrs(), import_control(), rt_notify() and get_route_info().
