vyatta-nat: check nat rules for errors before processing them for real
Errors in both source and destination NAT rules can cause either rules
to be overwritten (completely or partially), dropped entirely, or just
ending up with an inconsistent state in comparison to the current
configuration. This can lead to unpredictable NAT results, which can't
even be corrected by deleting all the nat rules, only a reboot will
correct the issue.
Checking these rules for consistency in a separate loop before they are
applied allows the errors to flagged up and the commit failed before
the nat table is touched.
Bug #493 http://bugzilla.vyos.net/show_bug.cgi?id=493
