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.

Removing stderr from the pict tool serves no purpose and drops valuable
information, we might use when debugging failed pairwise CI job, such
as:
Input Error: A parameter names must be unique
(cherry picked from commit 079debaa10)
The --enable-option-checking=fatal option prevents ./configure from
proceeding when an unknown option is used in the ./configure step in CI.
This change will avoid adding unsupported ./configure options or options
with typo or typo in pairwise testing "# [pairwise: ...]" marker.

Pairwise testing is a test case generation technique based on the
observation that most faults are caused by interactions of at most two
factors. For BIND, its configure options can be thought of as such
factors.
Process BIND configure options into a model that is subsequently
processed by the PICT tool in order to find an effective test vector.
That test vector is then used for configuring and building BIND using
various combinations of configure options.
