Remove /usr/share/examples/etc/bsd-style-copyright. /usr/share/examples/etc is supposed to hold the contents of an unchanged /etc directory only. Also, our template is in /COPYRIGHT so there is no point to keep a different one. Examples of n-clause BSD licenses are widely available online, when needed. Clean up newvers.sh, which was using the file for vers.c generation. There is no need to put a license on generated files, let alone such simple ones.
