    ip: update ip_said
    
    - like other ip_* types, implement using primatives such as
      raw ip_bytes
    - ttosa(const char *) -> ttosaid(shunk_t)
    - hopefully make jam_said() more robust
    - add said_protocol()
    - add said_is_unset()
    also:
    - protocol_by_prefix() -> protocol_by_caseeat_prefix()
    - fix some blank protocol names and descriptions
