unbound is not able to expand CNAMEs in local-data. Therefore we
have to do it manually at startup.

On virtual machines, it does not make sense to disable SMT for the
virtual cores. This has to be done by the hypervisor.

SMT can be forced on.
By default, all systems that are vulnerable to RIDL/Fallout
will have SMT disabled by default.
Systems that are not vulnerable to that will keep SMT enabled.

This is a feature that will filter adult content from search
engine's results.
The old method of rewriting the HTTP request no longer works.
This method changes the DNS response for supported search engines
which violates our belief in DNSSEC and won't allow these search
engines to ever enable DNSSEC.
However, there is no better solution available to this and this
an optional feature, too.

Force the initscript to remove the PID file when calling "stop" section.
If suricata crashes during startup, the PID file still remains and the service
cannot be started anymore until the file has been deleted.
Now when calling "stop" or "restart" the PID file will be deleted and the service
can be used again.

The script now will use the previously introduced seperate firewall chains called

The commit also creates an AND connection between the choosen network zones in the UI and

being created in syslog. So we skip searching for any sensors

If Tor is operating in relay mode, it has to open a lot of outgoing
TCP connections. These should be separated from any other outgoing
connections, as allowing _all_ outgoing traffic will be unwanted and
risky in most cases.
Thereof, Tor will be running as a dedicated user (see second patch),
allowing usage of user-based IPtables rulesets.
Partially fixes#11779.

We are using the netfilter MARK in IPsec & QoS and this
is causing conflicts.
Therefore, we use the highest bit in the IPS chain now
and clear it afterwards because we do not really care about
this after the packets have been passed through suricata.
Then, no other application has to worry about suricata.

These are a cause of worry because they are sometimes generated with
an invalid timestamp and therefore render unbound being unusable.
There is no strong reason to use self-signed certificates for extra
security here.
