Right.  Sorry if I didn't make that clear, I am proposing to remove
LdapMessageHandler but keep the handlers as implementing

I would rather grow into needing an interface.  I was able to remove
it in 5-10 minutes, so if someday we need a new interface, we can
certainly add one back.  Also, in my experience on numerous protocols,
you can alway pass what you need to handlers in MINA's
messageReceived() method as part of the IoSession.  For now this
interface is simply adding dead weight in the form of a do-nothing
init() method on every handler.
