Another take on LIBZMQ-568 to allow filtering IPC connections, this time using ZAP. This change is backward compatible. If the ZMQ_ZAP_IPC_CREDS option is set, the user, group, and process IDs of the peer process are appended to the address (separated by colons) of a ZAP request; otherwise, nothing changes. See LIBZMQ-568 and zmq_setsockopt documentation for more information.
