: NAT fixes

I've added these five patches to my tree, they fix NAT on loopback and problems with locally generated ICMP errors. If no one complains I'm going to push them to Dave this weekend.

Patrick McHardy:
o [NETFILTER]: Verify NAT manips have been applied before reversing
them in icmp_reply_translation
o [NETFILTER]: Apply PRE_ROUTING manips in LOCAL_OUT for locally
generated icmp errors
o [NETFILTER]: Save a level of indentation in icmp_reply_translation
o [NETFILTER]: Remove CONFIG_IP_NF_NAT_LOCAL config option
o [NETFILTER]: Release dst_entry in PRE_ROUTING after NAT

Regards
Patrick

JFYI: looks fine to me.
