This patch contains the following possible cleanups:
- make the following needlessly global variables static:
- core/rtnetlink.c: struct rtnl_msg_handlers[]
- netfilter/nf_conntrack_proto.c: struct nf_ct_protos[]
- make the following needlessly global functions static:
- core/rtnetlink.c: rtnl_dump_all()
- netlink/af_netlink.c: netlink_queue_skip()
