Ondřej Surý 58bd26b6cf 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.

/*%<
* Parse the null-terminated string 'string' containing a base 'base'
* integer, storing the result in '*uip'.
* The base is interpreted
* as in strtoul(). Unlike strtoul(), leading whitespace, minus or
* plus signs are not accepted, and all errors (including overflow)
* are reported uniformly through the return value.
*
* Requires:
*\li 'string' points to a null-terminated string
*\li 0 <= 'base' <= 36
*
* Returns:
*\li #ISC_R_SUCCESS
*\li #ISC_R_BADNUMBER The string is not numeric (in the given base)
*\li #ISC_R_RANGE The number is not representable as the requested type.
