[Click] Internal Handlers

[Cliff Frey]

Take a look at click/elements/standard/counter.cc to see a simple example of
one element that uses a handler of another... you can pass the handlers as
config parameters of your elements.

In some cases, it can be easier to just pass the element itself... For
instance you can pass an ARPTable element to an ARPQuerier element as a
parameter, allowing the ARPQuerier element to make calls directly to the
ARPTable element.
