ffdd9ddeae s4:dns_server: loudly warn when a tombstone record has other records
This shouldn't happen -- that is, there should never be non-tombstone
records in conjunction with a tombstone record -- and if it does, the
situation should resolve itself here. But the flow is confusing and
strange things sometimes happen often enough that it would be helpful
to know if this ever occurs.

f1fcbc0f10 s4-auth: pass lp_ctx to auth_generate_session_info() where possible
For non-testing callers of auth_generate_session_info(), passing
lp_ctx will allow us to correctly set a flag indicating if claims
should be evaluated.

For testing applications, the default will allow safe operation
inspecting the SID list.

76b0530e67 s4:dns_server: defer calling werr_to_dns_err() in a central place

This will allow us to create much better debug messages in

f241fe5d46 dns: Enable dnsserver_common install when not ad dc
dnsserver_common is enabled without the ad-dc to
prevent imports from failing when samba-tool is
called where the ad-dc was not built. The
server-side dns code is used in the client when
we do direct LDAP modification of DNS records.

51ace4d001 dns_record_match: drop pretense of HINFO support
We don't support it really, and if we did there is no sense in which
it could be updated, which is the context in which this function is
used.

(modern HINFO returns the constant string "RFC8482". See RFC 8482).

070e7113d4 dns: merge dlz/internal dns_records_match()
We have had three nearly identical functions called
dns_record[s]_match. This patch merges two of them, attempting to keep
the good bits and not the bugs.

That means:

1. We use the AAAA match from dlz, which is agnostic to all the
billions of ways you can write the same IPv6 address (case sensitivity
is just the beginning).

2. We lean more on the TXT match from dns_utils, because the dlz used
a weird bitwise &= operator, but we adjust to exit early.

3. Keep HINFO from dlz (for now).

4. Use the dns_name_equal() that was already in dns_common, which was
used by dlz. dns_utils had a strange one that probably did the same
thing.

f6025d9f34 dlz_bind9: remove redundant logging in b9_record_match()
This log message will never be seen. We know because:

1. Always (two places) we are comparing an incoming record against a
   database record.

2. The incoming record has come from b9_parse(), which makes the same
   check.

3. If the database record is bad, we will never get here because the
   first check is b9_record_match() is

       if (rec1->wType != rec2->wType) {
               return false;
       }

   and rec1->wType is not going to equal the corrupt database record's
   wType, because point 2.

OK, but why? So we can shift this into dnsserver_common.c, because
the internal dns server has an inferior record_match() and it could do
with sharing this one.
