Actively connect and produce a new_stream if things go well. The addr is the address that we are trying to connect with. The timeout is the amount of time to wait to connect. If it's 0 then we block indefinitely. If *timeout == {0, 0} then the connection is done using non-blocking mode. In this case, if the connection can't be made immediately the value of -1 is returned with <errno == EWOULDBLOCK>. If *timeout > {0, 0} then this is the maximum amount of time to wait before timing out. If the time expires before the connection is made <errno == ETIME>. The local_sap is the value of local address to bind to. If it's the default value of ACE_Addr::sap_any then the user is letting the OS do the binding. If reuse_addr == 1 then the local_addr is reused, even if it hasn't been cleanedup yet. The flags and perms arguments are passed down to the open() method.
