In dns_rpz_update_from_db we call setup_update which creates the db
iterator and calls dns_dbiterator_first. This unpauses the iterator and
might cause db->tree_lock to be acquired. We then do isc_task_send(...)
on an event to do quantum_update, which (correctly) after each iteration
calls dns_dbiterator_pause, and re-isc_task_sends itself.
That's an obvious bug, as we're holding a lock over an async task send -
if a task requesting write (e.g. prune_tree) is scheduled on the same
workers queue as update_quantum but before it, it will wait for the
write lock indefinitely, resulting in a deadlock.
To fix it we have to pause dbiterator in setup_update.

Remove another remnant of shared secret HMAC-MD5 support.
Explain that with currently recommended setups DNSKEY records are
inserted automatically, but you can still use $INCLUDE in other cases.

Use them in structs for various rdata types where they are missing.
This doesn't change the structs since we are replacing explicit
uint8_t field types with aliases for uint8_t.
Use dns_dsdigest_t in library function arguments.
Improve dnssec-cds with these more specific types.
(cherry picked from commit 0f219714e1)
Alphabetize options and synopsis; remove spurious -z from synopsis;
remove remnants of deprecated -k option; remove mention of long-gone
TSIG support; refer to -T KEY in options that are only relevant to
pre-RFC3755 DNSSEC; remove unnecessary -n ZONE from the example, and
add a -f KSK example.
(cherry picked from commit 1954f8d2bf)
5161. [func] named plugins are now installed into a separate
directory. Supplying a filename (a string without path
separators) in a "plugin" configuration stanza now
causes named to look for that plugin in that directory.
[GL #878]
(cherry picked from commit d2c960cfc2)
Illustrate the syntax for the policy options, with semicolons.
Explicitly mention the "default" policy.
Fix a few typos and remove some redundant wording.
