15// Summary:
16//   creates a socket for listening, and bind()s and listen()s it.
17// Args:
18//   host - hostname or numeric address, or empty-string if you want
19//          to bind to listen on all addresses
20//   port - a port number or service name. By service name I mean a
21//          -real- service name, not a Google service name. I'd suggest
22//          you just stick to a numeric representation like "80"
23//   is_numeric_host_address -
24//           if you know that the host address has already been looked-up,
25//           and will be provided in numeric form like "",
26//           then you can set this to true, and it will save you the time
27//           of a DNS lookup.
28//   backlog - passed into listen. This is the number of pending incoming
29//             connections a socket which is listening may have acquired before
30//             the OS starts rejecting new incoming connections.
31//   reuseaddr - if true sets SO_REUSEADDR on the listening socket
32//   reuseport - if true sets SO_REUSEPORT on the listening socket
33//   wait_for_iface - A boolean indicating that CreateListeningSocket should
34//                    block until the interface that it will bind to has been
35//                    raised. This is intended for HA environments.
36//   disable_nagle - if true sets TCP_NODELAY on the listening socket.
37//   listen_fd - this will be assigned a positive value if the socket is
38//               successfully created, else it will be assigned -1.
