netfilter: nf_conntrack: prepare namespace support for l3 protocol trackers
This patch prepares the namespace support for layer 3 protocol trackers.
Basically, this modifies the following interfaces:
* nf_ct_l3proto_[un]register_sysctl.
* nf_conntrack_l3proto_[un]register.
We add a new nf_ct_l3proto_net is used to get the pernet data of l3proto.
This adds rhe new struct nf_ip_net that is used to store the sysctl header
and l3proto_ipv4,l4proto_tcp(6),l4proto_udp(6),l4proto_icmp(v6) because the
protos such tcp and tcp6 use the same data,so making nf_ip_net as a field
of netns_ct is the easiest way to manager it.
This patch also adds init_net to struct nf_conntrack_l3proto to initial
the layer 3 protocol pernet data.
