From 0232747f04b650796db56fd7b487aee8a96fab03 Mon Sep 17 00:00:00 2001
From: Simo Sorce <simo@redhat.com>

Subject: Add function get_next_domain()

Use this function instead of explicitly calling domain->next

This function allows to get the next primary domain or to descend into the
subdomains and replaces also get_next_dom_or_subdom()
