Merge branch 'stdin'...

Merge branch 'stdin' Changes stdin channel from REQ-REQ to ROUTER-DEALER, fixing the round-robin load-balancing of stdin_requests across frontends. stdin_requests now go to the client that made the execute_request that prompted the stdin request. stdin_requests from frontends that do not support stdin will raise an error, rather than hanging on input that will never arrive. reviewed by @fperez closes
