Please find attached an updated version of the patch, it should do very
minimal things in the thread function.
It seems to work for me both when I have additional records in the SRV
response and when I haven't, valgrind didn't seems to complain and net
joins seems to work.
I need more tests but so

There was an alternative solution (that I have saved somewhere) where I
cheat with the struct dns_rr_srv structure to pass the struct addrinfo
back to the main thread by using the pointer to struct sockaddr_storage
to store the point to struct addrinfo.
But Jeremy was not very keen on it, so instead here is the variant where
there is a separate state structure for the resolve_one_name function.
