These patches implement a new mux client request to list the currently opened TCP forwardings. It also removes some todos regarding keeping the list of forwardings in the options up-to-date. Bert Wesarg (6): attach the forwarding type to struct Forward merge local and remote forward lists generate unique ids for forwardings to be used for identification remove closed forwardings from
