[Libvir] [patch 0/2] Couple more misc iptables related patches

[Mark McLoughlin]

Hey,
        Dan's suggestion to enable debug spew from spawned
processes with --enable-debug reminded me that the only
reason I wanted the NO_ERRORS stuff in the iptables code
was to avoid spewage when trying to add/delete builtin
iptables chains.

Cheers,
Mark.
