Alternative names : GstMultiChild

[edit] Interface API

• add methods to the interface like gst_parent_add_child(), gst_parent_rem_child-by_name|id() ? Or use another interface?
• if the GstParent interface provides the signals, how can implementing classes emit these (the signal ids are private)?
• whatfor do we need the signals anyway?
