Update the iptablesXXXX methods so that instead of directly executing iptables commands, they populate rules in an instance of virFirewallPtr. The bridge driver can thus construct the ruleset and then invoke it in one operation having rollback handled automatically. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
