libxt_set: new revision added

libipt_set renamed to libxt_set and the support for the forthcoming
ipset release added. I have tested backward (IPv4) and forward
compatibility (IPv4/IPv6):

ipset -N test iphash
ipset -A test test-address
iptables -N test-set
iptables -A test-set -j LOG --log-prefix "match "
iptables -A test-set -j DROP
iptables -A OUTPUT -m set --match-set test dst -j test-set
ping test-address

+This module matches IP sets which can be defined by ipset(8).

+where flags are the comma separated list of
+.BR "src"
+and/or
+.BR "dst" 
+specifications and there can be no more than six of them. Hence the command
+.IP
+ iptables \-A FORWARD \-m set \-\-match\-set test src,dst
+.IP
+will match packets, for which (if the set type is ipportmap) the source
+address and destination port pair can be found in the specified set. If
+the set type of the specified set is single dimension (for example ipmap),
+then the command will match packets for which the source address can be
+found in the specified set. 
+.PP
+The option \fB\-\-match\-set\fR can be replaced by \fB\-\-set\fR if that does 
+not clash with an option of other extensions.
+.PP
+Use of -m set requires that ipset kernel support is provided. As standard
+kernels do not ship this currently, the ipset or Xtables-addons package needs
+to be installed.
