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.

2988. [experimental] Added a "dlopen" DLZ driver, allowing the creation
of external DLZ drivers that can be loaded as
shared objects at runtime rather than linked with
named. Currently this is switched on via a
compile-time option, "configure --with-dlz-dlopen".
Note: the syntax for configuring DLZ zones
is likely to be refined in future releases.

2987. [func] Improve ease of configuring TKEY/GSS updates by
adding a "tkey-gssapi-keytab" option. If set,
updates will be allowed with any key matching
a principal in the specified keytab file.
"tkey-gssapi-credential" is no longer required
and is expected to be deprecated. (Contributed
