[NETFILTER]: Kill some supper dupper bloatry

/me awards the bloatiest-of-all-net/-.c-code award to
nf_conntrack_netlink.c, congratulations to all the authors :-/!

Hall of (unquestionable) fame (measured per inline, top 10 under
net/):
  -4496 ctnetlink_parse_tuple        netfilter/nf_conntrack_netlink.c
  -2165 ctnetlink_dump_tuples        netfilter/nf_conntrack_netlink.c
  -2115 __ip_vs_get_out_rt           ipv4/ipvs/ip_vs_xmit.c
  -1924 xfrm_audit_helper_pktinfo    xfrm/xfrm_state.c
  -1799 ctnetlink_parse_tuple_proto  netfilter/nf_conntrack_netlink.c
  -1268 ctnetlink_parse_tuple_ip     netfilter/nf_conntrack_netlink.c
  -1093 ctnetlink_exp_dump_expect    netfilter/nf_conntrack_netlink.c
  -1060 void ccid3_update_send_interval  dccp/ccids/ccid3.c
  -983  ctnetlink_dump_tuples_proto  netfilter/nf_conntrack_netlink.c
  -827  ctnetlink_exp_dump_tuple     netfilter/nf_conntrack_netlink.c

  (i386 / gcc (GCC) 4.1.2 20070626 (Red Hat 4.1.2-13) /
   allyesconfig except CONFIG_FORCED_INLINING)

...and I left < 200 byte gains as future work item.

After iterative inline removal, I finally have this:

net/netfilter/nf_conntrack_netlink.o:
 16 functions changed, 2122 bytes added, 11017 bytes removed, diff: -8895

Without a number of CONFIG.*DEBUGs, I got this:

 16 functions changed, 2122 bytes added, 11029 bytes removed, diff: -8907
