This updates all source files to use a new standard header for copyright

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

This populates DNS suffixes ("ts.net", etc) in /etc/resolver/* files
to point to 100.100.100.100 so MagicDNS works.
It also sets search domains.
