Description of problem:
iptables-save seems to get the --reject-with options icmp-proto-unreachable
and icmp-port-unreachable mixed up.

How reproducible:
Always

Steps to Reproduce:
1. iptables -A INPUT -p tcp -m tcp --dport 113 -j REJECT --reject-with
icmp-port-unreachable
2. iptables -L
3. iptables-save


Actual Results:  iptables -L output:
REJECT     tcp  --  anywhere             anywhere           tcp dpt:auth
reject-with icmp-port-unreachable

iptables-save output:
-A INPUT -p tcp -m tcp --dport 113 -j REJECT --reject-with
icmp-proto-unreachable


Expected Results:  iptables-save should have said:
-A INPUT -p tcp -m tcp --dport 113 -j REJECT --reject-with
icmp-port-unreachable


Additional info:

The bug also occurs the other way around (ie if the rule says
icmp-proto-unreachable, it will be saved as icmp-port-unreachable) This bug
seems fixed in the netfilter CVS, but I couldn't find anything about it in
the changelogs so maybe it was fixed accidently.
