[MaraDNS] MaraDNS update: b.root-servers.net IP change

[Sam Trenholme]

On October 24, 2017, the IPv4 IP for b.root-servers.net was changed. I
have updated Deadwood with the new IP. In addition, for anyone using a
dwood3rc file with the root servers set in it, the IP 192.228.79.201
needs to be replaced with 199.9.14.201.

A dwood3rc file for Deadwood sometimes has a section looking like this:

root_servers = {}
root_servers["."]="198.41.0.4, 199.9.14.201, 192.33.4.12, 199.7.91.13,"
root_servers["."]+="192.203.230.10, 192.5.5.241, 192.112.36.4, "
root_servers["."]+="198.97.190.53, 192.36.148.17, 192.58.128.30, "
root_servers["."]+="193.0.14.129, 199.7.83.42, 202.12.27.33"

If so, make sure the out of date 192.228.79.201 IP is replaced, like
it is above.

The deadwood configuration file is usually located at /etc/dwood3rc

I have updated the Deadwood source to use the updated IP, and have
updated the list of root servers everywhere the out of date IP was in
the documentation.

I plan on making a release of MaraDNS in 2018 with this update. Until
then, both the GitHub repo at https://github.com/samboy/MaraDNS and
the Deadwood snapshot at http://maradns.samiam.org/deadwood/snap have
this change.
