 Overall better to start using handles instead of map lookup by GID which
 only works for origin circuit.

 A HANDLE in the `circuit_t` object would allow us for instance to put in
 the circuit reference into a pubsub message instead of its raw pointer
 that could be freed during a mainloop event preceding the pubsub
 callback(s).
