xfrm/compat: Add 64=>32-bit messages translator
Provide the kernel-to-user translator under XFRM_USER_COMPAT, that
creates for 64-bit xfrm-user message a 32-bit translation and puts it
in skb's frag_list. net/compat.c layer provides MSG_CMSG_COMPAT to
decide if the message should be taken from skb or frag_list.
(used by wext-core which has also an ABI difference)
Kernel sends 64-bit xfrm messages to the userspace for:
- multicast (monitor events)
- netlink dumps
Wire up the translator to xfrm_nlmsg_multicast().
