hmmm.. yes I see.. Guess I got hung up on "virSocketAddr..." and didn't
focus as closely on the implementation where virSocketAddrParse can take
NULL as the first parameter... Guess, that means patches 2-5 can just be
called as:
if (virSocketAddrParse(NULL, pool->def->source.hosts[0].name,
AF_UNSPEC) < 0)
