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.

# This can be used to determine the label to use in a catalog zone to
# represent the specified zone. For example, the zone
# "domain.example" can be represented in a catalog zone called
# "catalog.example" by adding the following record:
#
# 5960775ba382e7a4e09263fc06e7c00569b6a05c.zones.catalog.example. \

#
# The label "5960775ba382e7a4e09263fc06e7c00569b6a05c" is the output of
