Recent python does not make parsetab.py successfully, because some token
regexp is starting with ?i flag. Remove that flag from regex and pass it
as extra flags parameter instead.
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.
(cherry picked from commit 58bd26b6cf)
4666. [bug] dnssec-keymgr: Domain names beginning with digits (0-9)
could cause a parser error when reading the policy
file. This now works correctly so long as the domain
name is quoted. [RT #45641]
4416. [bug] dnssec-keymgr: Domain names in policy files could
fail to match due to trailing dots. [RT #42807]
