af_iucv: Modify iucv msg target class using control msghdr
Allow 'classification' of socket data that is sent or received over
an af_iucv socket. For classification of data, the target class of an
(native) iucv message is used.
This patch provides the cmsg interface for iucv_sock_recvmsg() and
iucv_sock_sendmsg(). Applications can use the msg_control field of
struct msghdr to set or get the target class as a
"socket control message" (SCM/CMSG).
