A few changes for TTL processing:
...
- 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.

- ttl-zero-cacherep, Responses in the last second of their cache TTL,

get an extra second. That makes the TTL not 0, since they are from
cache and can be cached by the client.
