continue rendezvous refactor for gossip and repair

* remove trailing whitespace in ci/audit.sh

  * code review fixups
     * rename GOSSIP_PORT_RANGE => SOLANA_PORT_RANGE
     * remove out-of-date TODO in localnet-sanity.sh

  * remove features=test and code that was using it (localhost prohibitions in
      crdt) added TODO in crdt.rs, maybe we should boot localhost in production
      networks?

  * boot tvu_window from NodeInfo: instead, send repair requests from the repair
      socket (to gossip on peer) and answer repair requests via the sockaddr
      from the repair request

  * remove various unused pub functions

  * banish SocketAddr parse().unwrap() to a macro that can also accept simpler stuff
