efa5d84dcf dnssec-policy: reduce NSEC3 iterations to 150
When reducing the number of NSEC3 iterations to 150, commit
aa26cde2ae added tests for dnssec-policy
to check that a too high iteration count is a configuration failure.

The test is not sufficient because 151 was always too high for
ECDSAP256SHA256. The test should check for a different algorithm.

There was an existing test case that checks for NSEC3 iterations.
Update the test with the new maximum values.

Update the code in 'kaspconf.c' to allow at most 150 iterations.

313de3a7e2 Add purge-keys config option
Add a new option 'purge-keys' to 'dnssec-policy' that will purge key
files for deleted keys. The option determines how long key files
should be retained prior to removing the corresponding files from
disk.

If set to 0, the option is disabled and 'named' will not remove key
files from disk.

fd763d7223 enable listen-on parameters to be specified in any order
updated the parser to allow the "port", "tls" and "http"
paramters to "listen-on" and "listen-on-v6" to be specified in any
order. previously the parser would throw an error if any other order
was used than port, tls, http.

07f525bae5 require "tls none" for unencrypted HTTP listeners
unencrypted DoH connections may be used in some operational
environments where encryption is handled by a reverse proxy,
but it's going to be relatively rare, so we shouldn't make it
easy to do by mistake.  this commit changes the syntax for
listen-on and listen-on-v6 so that if "http" is specified, "tls"
must also be specified; for unencrypted listeners, "tls none"
can be used.

06951472dd Add parser support for DoH configuration options
This commit adds stub parser support and tests for:
- an "http" global option for HTTP/2 endpoint configuration.
- command line options to set http or https port numbers by
  specifying -p http=PORT or -p https=PORT.  (NOTE: this change
  only affects syntax; specifying HTTP and HTTPS ports on the
  command line currently has no effect.)
- named.conf options "http-port" and "https-port"
- HTTPSPORT environment variable for use when running tests.

437d271483 Special case tests for lmdb
When compiling BIND 9 without lmdb, this is promoted from
'not operational' to 'not configured', resulting in a failure (and no
longer a warning) if ldmb-related configuration options are set.

Special case certain system tests to avoid test failures on systems
that do not have lmdb.

87744f218d Remove a lot of obsoleted options
These options were ancient or made obsolete a long time ago, it is
safe to remove them.

Also stop printing ancient options, they should be treated the same as
unknown options.

Removed options: lwres, geoip-use-ecs, sit-secret, use-ixfr,
acache-cleaning-interval, acache-enable, additional-from-auth,
additional-from-cache, allow-v6-synthesis, dnssec-enable,
max-acache-size, nosit-udp-size, queryport-pool-ports,
queryport-pool-updateinterval, request-sit, use-queryport-pool, and
support-ixfr.

6f97bb6b1f Change nsec3param salt config to saltlen
Upon request from Mark, change the configuration of salt to salt
length.

Introduce a new function 'dns_zone_checknsec3aram' that can be used
upon reconfiguration to check if the existing NSEC3 parameters are
in sync with the configuration. If a salt is used that matches the
configured salt length, don't change the NSEC3 parameters.

7039c5f805 Check nsec3param configuration values
Check 'nsec3param' configuration for the number of iterations.  The
maximum number of iterations that are allowed are based on the key
size (see https://tools.ietf.org/html/rfc5155#section-10.3).

Check 'nsec3param' configuration for correct salt. If the string is
not "-" or hex-based, this is a bad salt.

5e47a13fd0 Warn if 'stale-refresh-time' < 30 (default)
RFC 8767 recommends that attempts to refresh to be done no more
frequently than every 30 seconds.

Added check into named-checkconf, which will warn if values below the
default are found in configuration.

BIND will also log the warning during loading of configuration in the
same fashion.

abdd4c89fc Add tests for "order none" RRset ordering rules
Make sure "order none" RRset ordering rules are tested in the
"rrsetorder" system test just like all other rule types are.  As the
check for the case of no "rrset-order" rule matching a given RRset also
tests "order none" (rather than "order random", as the test code may
suggest at first glance), replace the test code for that case so that it
matches other "order none" tests.

093af1c00a Drop $SYSTEMTESTTOP from bin/tests/system/
The $SYSTEMTESTTOP shell variable if often set to .. in various shell
scripts inside bin/tests/system/, but most of the time it is only
used one line later, while sourcing conf.sh. This hardly improves
code readability.

$SYSTEMTESTTOP is also used for the purpose of referencing
scripts/files living in bin/tests/system/, but given that the
variable is always set to a short, relative path, we can drop it and
replace all of its occurrences with the relative path without adversely
affecting code readability.

e43b3c1fa1 further tidying of primary/secondary terminology in system tests
this changes most visble uses of master/slave terminology in tests.sh
and most uses of 'type master' or 'type slave' in named.conf files.
files in the checkconf test were not updated in order to confirm that
the old syntax still works. rpzrecurse was also left mostly unchanged
to avoid interference with DNSRPS.

ba31b189b4 "check-names primary" and "check-names secondary" were ignored
these keywords were added to the parser as synonyms for "master"

checked for correctness.

978c7b2e89 Complete rewrite the BIND 9 build system
The rewrite of BIND 9 build system is a large work and cannot be reasonable
split into separate merge requests.  Addition of the automake has a positive
effect on the readability and maintainability of the build system as it is more
declarative, it allows conditional and we are able to drop all of the custom
make code that BIND 9 developed over the years to overcome the deficiencies of
autoconf + custom Makefile.in files.

This squashed commit contains following changes:

- conversion (or rather fresh rewrite) of all Makefile.in files to Makefile.am
  by using automake

- the libtool is now properly integrated with automake (the way we used it
  was rather hackish as the only official way how to use libtool is via
  automake

- the dynamic module loading was rewritten from a custom patchwork to libtool's
  libltdl (which includes the patchwork to support module loading on different
  systems internally)

- conversion of the unit test executor from kyua to automake parallel driver

- conversion of the system test executor from custom make/shell to automake
  parallel driver

- The GSSAPI has been refactored, the custom SPNEGO on the basis that
  all major KRB5/GSSAPI (mit-krb5, heimdal and Windows) implementations
  support SPNEGO mechanism.

- The various defunct tests from bin/tests have been removed:
  bin/tests/optional and bin/tests/pkcs11

- The text files generated from the MD files have been removed, the
  MarkDown has been designed to be readable by both humans and computers

- The xsl header is now generated by a simple sed command instead of
  perl helper

- The <irs/platform.h> header has been removed

- cleanups of configure.ac script to make it more simpler, addition of multiple
  macros (there's still work to be done though)

- the tarball can now be prepared with `make dist`

- the system tests are partially able to run in oot build

Here's a list of unfinished work that needs to be completed in subsequent merge
requests:

- `make distcheck` doesn't yet work (because of system tests oot run is not yet
  finished)

- documentation is not yet built, there's a different merge request with docbook
  to sphinx-build rst conversion that needs to be rebased and adapted on top of
  the automake

- msvc build is non functional yet and we need to decide whether we will just
  cross-compile bind9 using mingw-w64 or fix the msvc build

- contributed dlz modules are not included neither in the autoconf nor automake

644f0d958a dnssec-policy: to sign inline or not
When dnssec-policy was introduced, it implicitly set inline-signing.
But DNSSEC maintenance required either inline-signing to be enabled,
or a dynamic zone.  In other words, not in all cases you want to
DNSSEC maintain your zone with inline-signing.

Change the behavior and determine whether inline-signing is
required: if the zone is dynamic, don't use inline-signing,
otherwise implicitly set it.

You can also explicitly set inline-signing to yes with dnssec-policy,
the restriction that both inline-signing and dnssec-policy cannot
be set at the same time is now lifted.

However, 'inline-signing no;' on a non-dynamic zone with a
dnssec-policy is not possible.

5f464d15a0 dnssec-policy inheritance from options/view
'dnssec-policy' can now also be set on the options and view level and
a zone that does not set 'dnssec-policy' explicitly will inherit it
from the view or options level.

This requires a new keyword to be introduced: 'none'.  If set to
'none' the zone will not be DNSSEC maintained, in other words it will
stay unsigned.  You can use this to break the inheritance.  Of course
you can also break the inheritance by referring to a different
policy.

The keywords 'default' and 'none' are not allowed when configuring
your own dnssec-policy statement.

Add appropriate tests for checking the configuration (checkconf)
and add tests to the kasp system test to verify the inheritance
works.

Edit the kasp system test such that it can deal with unsigned zones
and views (so setting a TSIG on the query).

a50d707fdc Introduce dnssec-policy configuration
This commit introduces the initial `dnssec-policy` configuration
statement. It has an initial set of options to deal with signature
and key maintenance.

Add some checks to ensure that dnssec-policy is configured at the
right locations, and that policies referenced to in zone statements
actually exist.

Add some checks that when a user adds the new `dnssec-policy`
configuration, it will no longer contain existing DNSSEC
configuration options.  Specifically: `inline-signing`,
`auto-dnssec`, `dnssec-dnskey-kskonly`, `dnssec-secure-to-insecure`,
`update-check-ksk`, `dnssec-update-mode`, `dnskey-sig-validity`,
and `sig-validity-interval`.

Test a good kasp configuration, and some bad configurations.
