actor: Adds private _clutter_actor_get_n_children

Browse Source 
This adds a private getter to query the number of children an actor has.
One use planned for this API is to avoid calling get_paint_volume on
such actors. (It's not clear what the best semantics for
get_paint_volume are for actors with children, so we are considering
leaving the semantics undefined for the initial clutter 1.4 release)
