Lionel Flandrin 406c348771 Problem: ip_resolver allows wildcard ports for non-bindable sockets
Solution: return an error in this situation but still allow using an explicit
"0" if somebody really wants to connect to port 0.

This shouldn't break any existing code because a "*" port was already rejected
in an early test in the TCP path in zmq::socket_base_t::connect.
