75f9dd8e82 Simplify way we tag unreachable code with only ISC_UNREACHABLE()
Previously, the unreachable code paths would have to be tagged with:

    INSIST(0);
    ISC_UNREACHABLE();

There was also older parts of the code that used comment annotation:

    /* NOTREACHED */

Unify the handling of unreachable code paths to just use:

    UNREACHABLE();

The UNREACHABLE() macro now asserts when reached and also uses
__builtin_unreachable(); when such builtin is available in the compiler.

2bf7921c7e 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.

When we were printing quoted string, the double quotes where unescaped
leading to prematurely ending the quoted string.

b7c5bfb203 Extend ttlval to accept ISO 8601 durations
The ttlval configuration types are replaced by duration configuration
types. The duration is an ISO 8601 duration that is going to be used
for DNSSEC key timings such as key lifetimes, signature resign
intervals and refresh periods, etc. But it is also still allowed to
use the BIND ttlval ways of configuring intervals (number plus
optional unit).

A duration is stored as an array of 7 different time parts.
A duration can either be expressed in weeks, or in a combination of
the other datetime indicators.

Add several unit tests to ensure the correct value is parsed given
different string values.

02d95d0b62 update docbook grammar, removing dnssec-looksaide
- this required modification to the code that generates grammar text for
  the documentation, because the "dnssec-lookaside" option spanned more
  than one line in doc/misc/options, so grepping out only the lines
  marked "// obsolete" didn't remove the whole option.  this commit adds
  an option to cfg_test to print named.conf clauses only if they don't
  have the obsolete, ancient, test-only, or not-yet-implemented flags
  set.

0b8790967e named-checkconf -i: ignore deprecate warnings
Adds a new option to named-checkconf, -i.  If set, named-checkconf
will not warn you about deprecated options.  This allows people
to use named-checkconf in automated deployment precoesses where an
operator only cares if their conf is valid, even if it is not optimal.

This was added as a request as part of introducing a policy on
removing named.conf options.

6e0b93e5a0 implement searching of geoip2 database
- revise mapping of search terms to database types to match the
  GeoIP2 schemas.
- open GeoIP2 databases when starting up; close when shutting down.
- clarify the logged error message when an unknown database type
  is configured.
- add new geoip ACL subtypes to support searching for continent in
  country databases.
- map geoip ACL subtypes to specific MMDB database queries.
- perform MMDB lookups based on subtype, saving state between
  queries so repeated lookups for the same address aren't necessary.

  obsolete descriptions of BIND 8 behavior
- the log message for obsolete options explicitly recommends removal

4234968798 add a function for processing a list of configured plugins
Add a new libisccfg function, cfg_pluginlist_foreach(), which allows an
arbitrary callback to be invoked for every "plugin" stanza present in a
configuration object.  Use this function for both loading plugins and
checking their configuration in order to reduce duplication of
configuration processing code present in bin/named/server.c and
lib/bind9/check.c.

d2f4644388 add hook statement to configuration parser
- allow multiple "hook" statements at global or view level
- add "optional bracketed text" type for optional parameter list
- load hook module from specified path rather than hardcoded path
- add a hooktable pointer (and a callback for freeing it) to the
  view structure
- change the hooktable functions so they no longer update ns__hook_table
  by default, and modify PROCESS_HOOK so it uses the view hooktable, if
  set, rather than ns__hook_table. (ns__hook_table is retained for
  use by unit tests.)
- update the filter-aaaa system test to load filter-aaaa.so
- add a prereq script to check for dlopen support before running
  the filter-aaaa system test

not yet done:
- configuration parameters are not being passed to the filter-aaaa
  module; the filter-aaaa ACL and filter-aaaa-on-{v4,v6} settings are
  still stored in dns_view
