When fatal is called we may be holding memory allocated by OpenSSL.
This may result in the reference count for the FIPS provider not
going to zero and the shared library not being unloaded during
OPENSSL_cleanup. When the shared library is ultimately unloaded,
when all remaining dynamically loaded libraries are freed, we have
already destroyed the memory context we where using to track memory
leaks / late frees resulting in INSIST being called.
Disable triggering the INSIST when fatal has being called.
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.
