[iptables PATCH v2 2/3] libxtables: Add dccp and ipcomp to xtables_chain_protos

[Phil Sutter <phil@xxxxxx>]

There are "protocol extensions" for both just like with TCP or UDP.
Caching their values allows for implicit extension lookup after '-p'
flag, for instance:

| iptables -A FORWARD -p dccp --dport 1
| iptables -A FORWARD -p ipcomp --ipcompspi 18
