This commit deprecates the "dscp" configuration option and "dscp"
parameters to source-address configuration options (query-source,
transfer-source, etc.
(Note that the DSCP feature has not been fully operational since
the network manager was introduced in 9.16.0; outgoing DSCP values
can be configured, but incoming DSCP values are not detected.)
Deprecate auto-dnssec, add specific log warning to migrate to
dnssec-policy.
Cherry-picking triggered a lot of conflicts, so the changes
were manually picked.

After some back and forth, it was decidede to match the configuration
option with unbound ("so-reuseport"), PowerDNS ("reuseport") and/or
nginx ("reuseport").

Previously, the option to enable kernel load balancing of the sockets
was always enabled when supported by the operating system (SO_REUSEPORT
on Linux and SO_REUSEPORT_LB on FreeBSD).
It was reported that in scenarios where the networking threads are also
responsible for processing long-running tasks (like RPZ processing, CATZ
processing or large zone transfers), this could lead to intermitten
brownouts for some clients, because the thread assigned by the operating
system might be busy. In such scenarious, the overall performance would
be better served by threads competing over the sockets because the idle
threads can pick up the incoming traffic.
Add new configuration option (`load-balance-sockets`) to allow enabling
or disabling the load balancing of the sockets.

There is little point of listing all of the obsolete RFCs. I think it is
more likely confuse people than to do anything useful.
(cherry picked from commit 9437ea08e1)
For consistency with rest of the system, the grammar file and
the link anchors were renamed from "parentals" to "parental-agents".
Technically this is fixup for commit
90ef2b9c81.

The missing `::` in the .rst files caused grammar section in docs to
render empty.
The `::` was accidentally removed in an unrelated commit
58bd26b6cf which was supposed to update
only copyright headers.

As far as I can tell, it is some leftover from the times when Sphinx
docs were introduced (commit 9fb6d11abb).
It seems like it is not referenced from anywhere.

This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.

Similar to "notify-source" and "transfer-source", add options to
set the source address when querying parental agents for DS records.
(manually picked from commit 2872d6a12e)
Introduce a way to configure parental agents that can be used to
query DS records to be used in automatic key rollovers.
(manually picked from commit 0311705d4b)
Change the primaries configuration objects to the more generic
remote-servers, that we can reuse for other purposes (such as
parental-agents).
(manually picked from commit 39a961112f)
Add a new option 'purge-keys' to 'dnssec-policy' that will purge key
files for deleted keys. The option determines how long key files
should be retained prior to removing the corresponding files from
disk.
If set to 0, the option is disabled and 'named' will not remove key
files from disk.
(cherry picked from commit 313de3a7e2)
it is now an error to have two primaries lists with the same
name. this is true regardless of whether the "primaries" or
"masters" keywords were used to define them.
(cherry picked from commit f619708bbf)
as "type primary" is preferred over "type master" now, it makes
sense to make "primaries" available as a synonym too.
added a correctness check to ensure "primaries" and "masters"
cannot both be used in the same zone.

Upon request from Mark, change the configuration of salt to salt
length.
Introduce a new function 'dns_zone_checknsec3aram' that can be used
upon reconfiguration to check if the existing NSEC3 parameters are
in sync with the configuration. If a salt is used that matches the
configured salt length, don't change the NSEC3 parameters.

The current serve-stale implementation in BIND 9 stores all received
records in the cache for a max-stale-ttl interval (default 12 hours).
This allows DNS operators to turn the serve-stale answers in an event of
large authoritative DNS outage. The caching of the stale answers needs
to be enabled before the outage happens or the feature would be
otherwise useless.
The negative consequence of the default setting is the inevitable
cache-bloat that happens for every and each DNS operator running named.
In this MR, a new configuration option `stale-cache-enable` is
introduced that allows the operators to selectively enable or disable
the serve-stale feature of BIND 9 based on their decision.
The newly introduced option has been disabled by default,
e.g. serve-stale is disabled in the default configuration and has to be
enabled if required.

The ARM and the manpages have been converted into Sphinx documentation
format.
Sphinx uses reStructuredText as its markup language, and many of its
strengths come from the power and straightforwardness of
reStructuredText and its parsing and translating suite, the Docutils.

Change 5332 renamed "dnssec-keys" configuration statement to the
more descriptive "trust-anchors". Not all occurrences in the
documentation had been updated.
