-object.find( object, type, mode ): Find an object of given type. mode can
- be any of "parent", "child" and "anywhere". If set to "parent", it will
- look in "object"'s parent objects. If set to "child" it will look in
- "object"'s children. If set to "anywhere", it will look in all the
- objects. If object is unset, the current module's object will be used.
- Type can be: "libvlc", "playlist", "input", "decoder",
- "vout", "aout", "packetizer", "generic".
- This function is deprecated and slow and should be avoided.
-object.find_name( object, name, mode ): Same as above except that it matches
- on the object's name and not type. This function is also slow and should
- be avoided if possible.
