Relicense to 0BSD, update mail address

I've come to the conclusion that copyright mostly just stands in the way
of software development.  In my jurisdiction I cannot give up my own
copyright and 0BSD seems to be the closest thing to public domain.

The updated mail address, also used in my author/committer lines,
is shorter and looks nicer.  People rarely interact anyway.
