Since https://github.com/zeromq/libzmq/commit/350a1a, TCP addresses get resolved asynchronously, so zmq_connect no longer returned an error on incorrect addresses. This is troublesome since we rely on some error checking to catch blatant errors. Solution add some upfront syntax checking that catches at least the obvious kinds of errors (invalid characters, wrong or missing port number).
