In its "stop" and "panic" handlers, the iptables initscript refers to built-in chains "input", "output", and "forward".  There are no built-in chains with 
those names.  The proper names are "INPUT", "OUTPUT", and "FORWARD".

Reproducible: Always
Steps to Reproduce:
1. Set up an iptables-using kernel.  The chains can be empty, but be sure you have all of the right modules loaded up.
2. Run "service iptables stop" or "service iptables panic".

Actual Results:  Observed diagnostic output:  "iptables: Bad built-in chain name".

Expected Results:  Error-free execution of the initscript.
