This patch demonstrates using sendmsg() to avoid the memcpy() in
nfq_nlmsg_verdict_put_pkt().
This is a catch-up to the libnfnetlink-based nfq_set_verdict() function family
which already used sendmsg() to avoid data copy.
The logic is implemented in a number of static functions.
These functions are proposed as a starting point for additions to
libnetfilter_queue and libmnl.
This patch is an RFC on these functions.
