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.

Do not use <sys/sysctl.h> on Linux glibc 2.30 deprecated the <sys/sysctl.h> header [1]. However, that header is still used on other Unix-like systems, so only prevent it from being used on Linux, in order to prevent compiler warnings from being triggered.

Handle the errors from sysconf() call in isc_meminfo_totalphys() isc_meminfo_totalphys() would return invalid memory size when sysconf() call would fail, because ((size_t)-1 * -1) is very large number.
