You create a new pad and then set the appropriate chain function and
other functions on it, and then you add it to the element. You either do
this in your instance init function, if the pad always exist, or in the
request pad virtual function, if it's a request pad, or whenever you
have to add it (don't forget to activate the pad if you add it at
runtime later).
