memory used by waiting tcp and tls stream replies. This avoids
a denial of service where these replies use up all of the memory.

- Remove unused if clause in testcode.

resilience of the server. The so-reuseport, harden-below-nxdomain,
and minimal-responses options are enabled by default. They used
to be disabled by default, waiting to make sure they worked. They
are enabled by default now, and can be disabled explicitly by
setting them to "no" in the unbound.conf config file. The reuseport
and minimal options increases speed of the server, and should be
otherwise harmless. The harden-below-nxdomain option works well
together with the recently default enabled qname minimisation, this
causes more fetches to use information from the cache.

This limits the number of simultaneous TCP client connections

is unaffected.

- [dnscrypt] introduce dnscrypt-provider-cert-rotated option,
from Manu Bretelle.
This option allows handling multiple cert/key pairs while only
distributing some of them.
In order to reliably match a client magic with a given key without
strong assumption as to how those were generated, we need both key and
cert. Likewise, in order to know which ES version should be used.
On the other hand, when rotating a cert, it can be desirable to only
serve the new cert but still be able to handle clients that are still
using the old certs's public key.
The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not
publish the cert as part of the DNS's provider_name's TXT answer.
