Write simple ACCEPT rules to the filter table.

This gets us closer to passing the iptables tests and opens up iptables
so it can be worked on by multiple people.

A few restrictions are enforced for security (i.e. we don't want to let
users write a bunch of iptables rules and then just not enforce them):

- Only the filter table is writable.
- Only ACCEPT rules with no matching criteria can be added.
