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.

* \brief Calculate a hash over data.
|
|
*
|
|
* This hash function is useful for hashtables. The hash function is
|
|
* opaque and not important to the caller. The returned hash values are
|
|
* non-deterministic and will have different mapping every time a
|
|
* process using this library is run, but will have uniform
|
|
* distribution.
|
|
*
|
|
* isc_hash_32/64() calculates the hash from start to end over the
|
|
* input data.
|
|
*
|
|
* 'data' is the data to be hashed.
|
|
*
|
|
* 'length' is the size of the data to be hashed.
|
|
*
|
|
* 'case_sensitive' specifies whether the hash key should be treated as
|
|
* case_sensitive values. It should typically be false if the hash key
|
|
* is a DNS name.
|
|
*
|
|
* Returns:
|
|
* \li 32 or 64-bit hash value
