Log message:
Bugfix: uninitialized variable causing getsockname to fail and trigger
other bugs.

In s_auth.c:103, insert:
  len = sizeof(sock);

just before:
  if (getsockname(cptr->fd, (struct sockaddr *)&sock, &len) == -1
      || (sock.sin_port = 0)    /* Reset sin_port and let OS choose
      || bind(cptr->authfd, (struct sockaddr *)&sock, len) == -1)

This initialises len correctly, and everything then works :)

--
On a sidenote, I noticed the result of this failure is that the clients
socket is closed, surely closing the authfd would be better than just
cutting off the client? :P
The authfd then never gets closed, and also the ircd hits 100% cpu,
presumably because this client is still in a list somewhere, but with a
closed Fd, maybe, not looked :)
