maybe_serialize() should serialize strings that are already serialized — at Version 3

Description (last modified by ryan)
 changed the behavior of maybe_serialize(). Instead of serializing an already serialized string, the string was returned as is. This broke plugins that passed serialized data to update_option()/get_option() expecting it to come back serialized. Instead it came back unserialized.
