netfilter: nf_conntrack: prepare namespace support for l4 protocol trackers
This patch prepares the namespace support for layer 4 protocol trackers.
Basically, this modifies the following interfaces:
* nf_ct_[un]register_sysctl
* nf_conntrack_l4proto_[un]register
to include the namespace parameter. We still use init_net in this patch
to prepare the ground for follow-up patches for each layer 4 protocol
tracker.
We add a new net_id field to struct nf_conntrack_l4proto that is used
to store the pernet_operations id for each layer 4 protocol tracker.
Note that AF_INET6's protocols do not need to do sysctl compat. Thus,
we only register compat sysctl when l4proto.l3proto != AF_INET6.
