Add an options parameter to control what rdatasets are returned when
iteratating over the node. Specific modes will be added later.

There were a number of places where the zone table should have been
locked, but wasn't, when dns_zt_apply was called.
Added a isc_rwlocktype_t type parameter to dns_zt_apply and adjusted
all calls to using it. Removed locks in callers.

dohpath is specfied in draft-ietf-add-svcb-dns and has a value
of 7. It must be a relative path (start with a /), be encoded
as UTF8 and contain the variable dns ({?dns}).

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.

The C17 standard deprecated ATOMIC_VAR_INIT() macro (see [1]). Follow
the suite and remove the ATOMIC_VAR_INIT() usage in favor of simple
assignment of the value as this is what all supported stdatomic.h
implementations do anyway:
* MacOSX.plaform: #define ATOMIC_VAR_INIT(__v) {__v}
* Gcc stdatomic.h: #define ATOMIC_VAR_INIT(VALUE) (VALUE)

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.

The dst_key_pubcompare() and dst_key_compare() didn't have a unit test,
add the unit tests which test comparing the same keys, different keys,
and, where possible, similar keys with a manually altered parameter.
dst_key_pubcompare() internally uses the *_todns() functions of the
lib/dns/openssl*_link.c modules.
dst_key_compare() internally uses the *_compare() functions of the
lib/dns/openssl*_link.c modules.
This commit adds a unittest that tests private rdataset_getownercase()
and rdataset_setownercase() methods from rbtdb.c. The test setups
minimal mock dns_rbtdb_t and dns_rbtdbnode_t data structures.
As the rbtdb methods are generally hidden behind layers and layers, we
include the "rbtdb.c" directly from rbtdb_test.c, and thus we can use
the private methods and data structures directly. This also opens up
opportunity to add more unittest for the rbtdb private functions without
going through all the layers.

if dns_updatemethod_date is used do that the returned method is only
set to dns_updatemethod_increment if the new serial does not encode
the current day (YYYYMMDDXX).

this rolls up numerous changes that have been applied to the
main branch, including moving isc_task operations into the
netmgr event loops, and other general stabilization.
This commit adds POSIX nanosleep() and usleep() shim implementation for
Windows to help implementors use less #ifdef _WIN32 in the code.

* The location of the digest type field has changed to where the
reserved field was.
* The reserved field is now called scheme and is where the digest
type field was.
* Digest type 2 has been defined (SHA256).

It is more intuitive to have the countdown 'max-stale-ttl' as the
RRset TTL, instead of 0 TTL. This information was already available
in a comment "; stale (will be retained for x more seconds", but
Support suggested to put it in the TTL field instead.

The USE_OPENSSL constraint in dh_test does not seems to be necessary
anymore, the test runs with PKCS#11 as well.

Make sure lib/dns/tests/dnstap_test returns an exit code that indicates
a skipped test when dnstap is not enabled.
(cherry picked from commit c286341703)
BIND 9.17 changed exit code of skipped test to meet Automake
expectations in fa505bfb0e. BIND 9.16 was
not rewritten to Automake, but for consistency reasons, the same
SKIPPED_TEST_EXIT_CODE preprocessor macro is used (though the actual
exit code differs from the one in BIND 9.17).

When using the `unixtime` or `date` method to update the SOA serial,
`named` and `dnssec-signzone` would silently fallback to `increment`
method to prevent the new serial number to be smaller than the old
serial number (using the serial number arithmetics). Add a warning
message when such fallback happens.
(cherry picked from commit ef685bab5c)
Add unit test to ensure the right NSEC3PARAM event is scheduled in
'dns_zone_setnsec3param()'. To avoid scheduling and managing actual
tasks, split up the 'dns_zone_setnsec3param()' function in two parts:
1. 'dns__zone_lookup_nsec3param()' that will check if the requested
NSEC3 parameters already exist, and if a new salt needs to be
generated.
2. The actual scheduling of the new NSEC3PARAM event (if needed).

Make sure pointer checks in unit tests use cmocka assertion macros
dedicated for use with pointers instead of those dedicated for use with
integers or booleans.

The clang 12 has a new warning that warns when using multi-line strings
in the string arrays, f.e.:
{ "aa",
"b"
"b",
"cc" }
would generate warning like this:
private_test.c:162:7: error: suspicious concatenation of string literals in an array initialization; did you mean to separate the elements with a comma? [-Werror,-Wstring-concatenation]
"33333/RSASHA1" };
^
private_test.c:161:7: note: place parentheses around the string literal to silence warning
"Done removing signatures for key "
^
private_test.c:197:7: error: suspicious concatenation of string literals in an array initialization; did you mean to separate the elements with a comma? [-Werror,-Wstring-concatenation]
"NSEC chain",

private_test.c:196:7: note: place parentheses around the string literal to silence warning
"Removing NSEC3 chain 1 0 30 DEAF / creating "
^
2 errors generated.

The dns_message_create() function cannot soft fail (as all memory
allocations either succeed or cause abort), so we change the function to
return void and cleanup the calls.
(cherry picked from commit 33eefe9f85)
This commit will be used as a base for the next code updates in
order to have a better control of dns_message_t objects' lifetime.

When a library is examined, an object file within it can be left out
of the link if it does not provide symbols that the symbol table
needs. Introducing `isc_stdtime_tostring` caused a build failure for
`update_test` because it now requires `libisc.a(stdtime.o)` and that
also exports the `isc_stdtime_get` symbol, meaning we have a
multiple definition error.
Add a local version of `isc_stdtime_tostring`, so that the linker
will not search for it in available object files.
Originally, every library and binaries got linked to everything, which
creates unnecessary overlinking. This wasn't as straightforward as it
should be as we still support configuration without libtool for 9.16.
Couple of smaller issues related to include headers and an issue where
sanitizer overload dlopen and dlclose symbols, so we were getting false
negatives in the autoconf test.
