* Do not initialize quic_table unless it is enabled
Fedora in FIPS mode might fail to initialize ngtcp2 library, because
some ciphers desired are not available.
Make it possible to skip initialization by setting explicitly quic_port
to 0. Unless we have some listeners for port 853 configured, skip its
initialization as well.

* Fix typo in logged function name
- On fast_reload, the identity and version strings are always freed and
reallocated as part of dt_apply_cfg(). Add fr_worker_pickup_dnstap_changes()
to copy any changes from daemon to workers.
* Statistics counter for number of queries dropped by limit on reply addresses
Request list entries can be associated with multiple pending "reply
addresses". Basically each request list entry keeps its own list of
clients that should receive the response once the recursion is finished.
This requires keeping allocations around for each client, and there is
a global limit on the number of *additional* reply addresses that can
be allocated. (Each new request list entry seems to get its own initial
reply address which is not counted against the limit.)
This commit adds a statistics counter "num_queries_replyaddr_limit" that
counts the number of incoming client queries that have been dropped due
to the restriction on allocating additional reply addresses. This allows
distinguishing these drops from other kinds of drops.
* Statistics counter for number of mesh reply entries
Request list entries can be associated with multiple pending "reply
addresses". Since there is a limit on the number of additional reply
addresses that can be allocated which can cause incoming queries to be
dropped if exceeded, it would be nice to be able to track this number.
This commit basically exports the mesh_area's internal counter
`num_reply_addrs` as "threadX.requestlist.current.replies" /
"total.requestlist.current.replies".
* 'tls-use-system-policy-versions' is introduced to allow Unbound to use
any system available TLS version when serving TLS.

- Cached messages that reach 0 TTL are considered expired. This prevents
Unbound itself from issuing replies with TTL 0 and possibly causing a
thundering herd at the last second. Upstream replies of TTL 0 still
get the usual pass-through but they are not considered for caching
from Unbound or any of its caching modules.
- 'serve-expired-reply-ttl' is changed and is now capped by the original
TTL value of the record to try and make some sense when replying
with expired records.
- TTL decoding was updated to adhere to RFC8767 section 4 where a set
high-order bit means the value is positive instead of 0.
