7d255e5c23 lib/addns: match additional names in a non case insensitive way 
Sometime proxy dns servers mess up the case of parts of the
name...

So we should match with strequal() instead of strcmp(),
which results in much less dns packets on the wire...

f32d43763d dns: fix comments and make s4/libcli/resolve dns resolver working 
After migrating to use libaddns, reply_to_addrs() needed to change the
way answers are iterated through. Originally libroken implementation
gave all answers as separate records with last one being explicitly NULL.
libaddns unmarshalling code gives all non-NULL answers and should be
iterated with explicit reply->num_answers in use.
