httpd: prefer AES-GCM ciphers over AES-CBC
CBC ciphers are vulnerable to a bunch of attacks (being
rather academic so far) such as MAC-then-encrypt or
padding oracle.
These seem to be more serious (see
https://blog.qualys.com/technology/2019/04/22/zombie-poodle-and-goldendoodle-vulnerabilities
for further readings) which is why they should be used
for interoperability purposes only.
I plan to remove AES-CBC ciphers for the WebUI at the
end of the year, provided overall security landscape
has not changed until that.
(AES-CBC + ECDSA will be preferred over RSA for performance
reasons. As this cipher order cannot be trivially rebuilt with
OpenSSL cipher stings, it has to be hard-coded.)
All working clients will stay compatible.

unbound: Add Safe Search
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.

make.sh: Mount /usr/src in memory for faster build
This patch enables that /usr/src is a ramdisk which should
give us fewer I/O operations when extracting tarballs or
writing small intermediate files by the compiler.
In some virtualised environments this should bring a good
performance boost.
There is no persistent data stored in this directory and
some persistent directories are mounted over it.

Config: Disable XZ parallelism by default
Exporting XZ_OPT caused that every time xz was called, it automatically
enabled parallelism. The make systemm also launches multiple processes
at the same time to use more processor cores at the same time.
The combination of this causes memory exhaustion even on large systems
and has no performance gain. Therefore this is disabled by default
and only enabled where we need it which is already the case.

routing: Fix potential authenticated XSS in input processing
An authenticated Stored XSS (Cross-site Scripting) exists in the
(https://192.168.0.241:444/cgi-bin/routing.cgi) Routing Table Entries
via the "Remark" text box or "remark" parameter. This is due to a
lack of user input validation in "Remark" text box or "remark"
parameter. It allows an authenticated WebGUI user with privileges
for the affected page to execute Stored Cross-site Scripting in
the Routing Table Entries (/cgi-bin/routing.cgi), which helps
attacker to redirect the victim to a attacker's phishing page.
The Stored XSS get prompted on the victims page whenever victim
tries to access the Routing Table Entries configuraiton page.
An attacker get access to the victim's session by performing
the CSRF and gather the cookie and session id's or possibly can
change the victims configuration using this Stored XSS.
This attack can possibly spoof the victim's informations.

INPUT/OUTPUT rules, too. Those were slightly invalid because
the source and destination interfaces where passed, too.
This could render some rules in certain circumstances useless.
