Ondřej Surý 58bd26b6cf Update the copyright information in all files in the repository
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.

Notes for BIND 9.17.18
----------------------
New Features
~~~~~~~~~~~~
- Support for HTTPS and SVCB record types has been added. :gl:`#1132`
Feature Changes
~~~~~~~~~~~~~~~
- When ``dnssec-signzone`` signs a zone using a successor key whose
predecessor is still published, it now only refreshes signatures for
RRsets which have an invalid signature, an expired signature, or a
signature which expires within the provided cycle interval. This
allows ``dnssec-signzone`` to gradually replace signatures in a zone
whose ZSK is being rolled over (similarly to what ``auto-dnssec
maintain;`` does). :gl:`#1551`
- ``dnssec-cds`` now only generates SHA-2 DS records by default and
avoids copying deprecated SHA-1 records from a child zone to its
delegation in the parent. If the child zone does not publish SHA-2 CDS
records, ``dnssec-cds`` will generate them from the CDNSKEY records.
The ``-a algorithm`` option now affects the process of generating DS
digest records from both CDS and CDNSKEY records. Thanks to Tony
Finch. :gl:`#2871`
- When reporting zone types in the statistics channel, the terms
``primary`` and ``secondary`` are now used instead of ``master`` and
``slave``, respectively. :gl:`#1944`
Bug Fixes
~~~~~~~~~
- A recent change to the internal memory structure of zone databases
inadvertently neglected to update the MAPAPI value for zone files in
``map`` format. This caused version 9.17.17 of ``named`` to attempt to
load files into memory that were no longer compatible, triggering an
assertion failure on startup. The MAPAPI value has now been updated,
so ``named`` rejects outdated files when encountering them.
:gl:`#2872`
- Zone files in ``map`` format whose size exceeded 2 GB failed to load.
This has been fixed. :gl:`#2878`
- Stale data in the cache could cause ``named`` to send non-minimized
queries despite QNAME minimization being enabled. This has been fixed.
:gl:`#2665`
- When a DNSSEC-signed zone which only has a single signing key
available is migrated to ``dnssec-policy``, that key is now treated as
a Combined Signing Key (CSK). :gl:`#2857`
- When a dynamic zone was made available in another view using the
``in-view`` statement, running ``rndc freeze`` always reported an
``already frozen`` error even though the zone was successfully
frozen. This has been fixed. :gl:`#2844`
