If the OpenSSL SHA1_{Init,Update,Final} API is still available, use it.
The API has been deprecated in OpenSSL 3.0, but it is significantly
faster than EVP_MD API, so make an exception here and keep using it
until we can't.
(cherry picked from commit 25db8d0103)
Instead of going through another layer, use OpenSSL EVP_MD API directly
in the isc_iterated_hash() implementation. This shaves off couple of
microseconds in the microbenchmark.

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.
