Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Allow conntrack entries with l3num == NFPROTO_IPV4 or == NFPROTO_IPV6
   only via ctnetlink, from Will McVicker.

2) Batch notifications to userspace to improve netlink socket receive
   utilization.

3) Restore mark based dump filtering via ctnetlink, from Martin Willi.

4) nf_conncount_init() fails with -EPROTO with CONFIG_IPV6, from
   Eelco Chaudron.

5) Containers fail to match on meta skuid and skgid, use socket user_ns
   to retrieve meta skuid and skgid.
