3b13d4d65a s3: libsmb: Add utility function sockaddr_storage_to_samba_sockaddr().
As requested by Andreas and Metze, ensure new code uses
struct samba_sockaddr. This is part of changing dns_lookup_list_async()
and callers to use struct samba_sockaddr.

Currently putting this into namequery.c even though it's
used inside dsgetdcname.c as I have future patches that
heavily make use of this to convert sockaddr_storage -> samba_sockaddr.

I'm not committed to putting it here, it may fit better
in lib/util/util_net.[ch]. It just needs to be somewhere
other functions inside source/libsmb/*.c can get to it,
and currently namequery.h exports the most stuff.

Not yet used.

5ffcd883dd s3: libsmb: Add dns_lookup_list_async() - not yet used.
Take a list of hostnames and does async A and AAAA (if
supported) lookups on them. Interface compatible with
dns_lookup_list() (with the addition of one extra
parameter returning the query name list, for use inside
dsgetdcname() internals later) and we'll replace it in the next
commit. Waits for lp_get_async_dns_timeout() seconds to complete.

Commented out as not yet used.

04b2db7d88 libsmb: Fix CID 1465656 Resource leak
This is very likely a false positive, because Coverity does not see
that we only assign "dns_addrs" when NT_STATUS_IS_OK(status), so we
might not want this. But it is a fresh finding and looks cleaner this
way.

d53ade5beb s3: libsmb: Rewrite resolve_ads() to use the previously added dns_lookup_list() function.
Clean up internals - a LOT.

This one needs careful review. Ditch the (unused) port returns from
the SRV replies.

Internally uses talloc'ed arrays of struct sockaddr_storage
which it then convert to MALLOC'ed struct ip_service.

Still returns struct ip_service but this will be
fixed in the next commit.

d0fa32bdcd s3: libsmb: Add in (currently unused) function dns_lookup_list().
This function takes a list of names returned from a DNS SRV
query which didn't have returned IP addresses and returns an
array of struct sockaddr_storage.

Currently synchronous, but this is the function that will
be changed to be asynchronous later.

Compiles but commented out for now so we don't get "unused
function" warnings.

No memory leaks as this is used for transient data and is cleaned up
