to be used by resolved to route DNS request to specific network interfaces, the latter is to be used for searching
single-label hostnames with (in addition to being used for routing). Both settings are configured in the "Domains="
setting. Normal domain names listed in it are now considered search domains (for compatibility with existing setups),
while those prefixed with "~" are considered routing domains only. To route all lookups to a specific interface the
routing domain "." may be used, referring to the root domain. An alternative syntax for this is the "*", as was already
implemented before using the "wildcard" domain concept.

coredump: fix bug that loses core dump files when core dumps are compressed and disk space is low.
Previously the save_external_coredump function returned a file
descriptor corresponding to the dumped file. This descriptor was used
for two different purposes by calling code: a) access to the raw core
dump data; b) testing candidate files (via inode comparisons) while
vacuuming to protect the current core dump from vacuuming.
The descriptor returned always corresponded to a file containing the raw
core dump data. However if compresson was used and the core dump was
compressed then the descriptor returned did not correspond to the file
that would eventually be left on disk (ie the compressed file). Thus
the file was never protected by vacuuming. When disk space was low all
core dumps including the current one would be vacuumed and the
corresponding log message referred to a file that no longer existed.
This resulted in the following error message from coredumpctl if the
missing core dump was requested:
Cannot retrieve coredump from journal nor disk.
Failed to retrieve core: No such file or directory
save_external_coredump now returns two descriptors, one to be used for
inode comparisons to prevent overzealous vacuuming and one to be used
for raw data access. When compression is not used the returned inode
comparison descriptor will be invalid, indicating that the raw data
access descriptor should be used for inode comparisons as well.
Corresponding use of save_external_coredump and the returned
descriptors also updated.

negative responses, and if they are missing then, then message will be considered unsigned, which hence means the
outcome is effectively the same.

However, for the catalog files we really should stick to 79 chars, as they are regularly shown on terminal screens.

If we downgrade from DNSSEC to non-DNSSEC mode, let's log about this in a recognizable way (i.e. with a message ID),

resolved: when synthesizing RR responses, own the name fully
When we synthesize A/AAAA for domains like "localhost", then make sure we generate ENODATA if the user asks for RR
types such a RP to be solved on the name. Previously, we'd pass the error back in that case that was generated from the
usual lookup procedure.

resolved: properly handle LLMNR/TCP connection errors
The LLMNR spec suggests to do do reverse address lookups by doing direct LLMNR/TCP connections to the indicated
address, instead of doing any LLMNR multicast queries. When we do this and the peer doesn't actually implement LLMNR
this will result in a TCP connection error, which we need to handle. In contrast to most LLMNR lookups this will give
us a quick response on whether we can find a suitable name. Report this as new transaction state, since this should
mostly be treated like an NXDOMAIN rcode, except that it's not one.

core: normalize error handling a bit, in setup_pam()
Assign errno-style errors to a variable called "r" when they happen, the same way we do this in most other calls. It's
bad enough that the error handling part of the function deals with two different error variables (pam_code and r) now,
but before this fix it was even three!

Since we honour the edns rcode extension we need more than 4 bits to format it. To avoid further confusion, derive the

resolved: never store NSEC/NSEC3 RRs from the upper zone of a zone cut in cache
When using NSEC/NSEC3 RRs from the cache to derive existance of arbitrary RRs, we should not get confused by the fact
that NSEC/NSEC3 RRs exist twice at zone cuts: once in the parent zone, and once in the child zone. For most RR types we
should only consult the latter since that's where the beef is. However, for DS lookups we have to check the former.
This change makes sure we never cache NSEC/NSEC3 RRs from any parent zone of a zone-cut. It also makes sure that when
we look for a DS RR in the cache we never consider any cached NSEC RR, as those are now always from the child zone.

resolve: use different bitmap checking rules when we find an exact NSEC3 match, or just a covering enclosure
If we are looking for a DS RR we need to check the NSEC3 bitmap of the parent zone's NSEC3 RR, not the one from the
child. For any other RR we need to look at the child's however, hence enforce this with the bitmaps.
Note that not coverign checks only the lower zone's NSEC3 bitmaps matter, hence the existing check is fine.
