DNS resolution in 'make test'

while working on MIT Kerberos stuff it became clear that we need to talk to 
DNS server to ask it about SRV records for the KDC.

I've did some investigation and wrote a resolv_wrapper library to wrap 
res_init(), res_query() and res_search(). It is a really simple wrapper and 
I'm able to talk to the Samba DNS server in 'make test' now!
