The conntrackd daemon lacks support for syncing IPv6 NATed connections.
This patch adds support for managing the IPv6 part of struct __nfct_nat,
also updating the corresponsing symbols.

The conntrackd daemon lacks support for syncing IPv6 NATed connections.
This patch prepares the ground to give support to such operations:
* replace uint32_t with union __nfct_address in struct __nfct_nat.
* update all users of the former uint32_t to support the new struct
A follow-up patch gives support to actually manage the IPv6 NAT.

This patch adds the front-end to the recent ctnetlink interface

allows to set/clear only a subset of the in-kernel label set, e.g.
"set bit 1 and do not change any others".

adds new labelmap api to create a name <-> bit mapping
from a text file (default: /etc/xtables/connlabel.conf).
nfct_labelmap_new(filename) is used to create the map,
nfct_labelmap_destroy() releases the resources allocated for the map.
Two functions are added to make map lookups:
nfct_labelmap_get_name(map, bit) returns the name of a bit,
nfct_labelmap_get_bit returns the bit associated with a name.
The connlabel attribute is represented by a nfct_bitmask object, the
nfct_bitmask api can be used to test/set/get individual bits
("labels").
The exisiting nfct_attr_get/set interfaces can be used to read or
replace the existing labels associated with a conntrack with a new set.

This adds the ATTR_HELPER_INFO that can be used to send binary data
that will be attached to the conntrack. This is useful for the
user-space connection tracking support.
This patch also adds a new interface:
nfct_set_attr_l(attr, type, value, length);
that is used to set the variable length helper information.

This patch adds support to build and to parse netlink messages
from/to one user-space nf_conntrack object. It uses libmnl, thus
libnetfilter_conntrack now depends on this library.

This is the first patch in the direction of removing the dependency
on the veteran libnfnetlink.
I have decided to update LIBVERSION in this patch. I know it's
recommended to do this before releasing the software. I prefer to
do this so snapshot packages get the correct LIBVERSION.
