[core] save parsed listen addrs at startup

save parsed listen addrs at startup for reuse at runtime

srv_socket->srv_token is normalized at startup and contains IP and port.
save offset to colon, if present, or else length of string (unix socket)

At runtime, srv_token_colon can be quickly used as length of IP string
(without port) or, if not length of string, offset of stringified port
following the colon.
