CLEANUP: listeners: remove unused disable_listener and disable_all_listeners

These ones have never been called, they were referenced by the protocol's
disable_all for some protocols but there are no traces of their use, so
in addition to not being sure the code works, it has never been tested.
Let's remove a bit of complexity starting from there.
