- Fix NSEC3 code to not break on broken auth zones that include unsigned
out of zone (above apex) data. Could lead to hang while trying to
prove a wildcard answer.
Reported by Dmitrii Kuvaiskii from Amazon Web Services.
- Tests for NSEC3 auth zones with out of zone data.
- Auto-configure '-slabs' values to a power of 2 value close to num-threads
by default for multi-threaded environments.

(configurable) infra-cache-max-rtt value. That could result in
infra-keep-probing not working if an infra-cache-max-rtt value was chosen
that was below 12000 ms. This fix still uses a default value of 12000
ms for the probe but caps it to the infra-cache-max-rtt if that is
lower.
Fixes#1185 by creating the SSL_CTX for QUIC before chroot and
privilege drop, just like the other SSL_CTX creations.
