Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Discussed with: imp, rwatson
- use termios, not sgtty
- dont use _putchar(), that was a BSD-curses specific feature not in
other curses packages (such as ncurses)
- use sigaction, not sigvec while I'm there
- box() does different things under sysv/ncurses on 1-line high windows,
and BSD-curses doesn't have hline(), so do it by adding characters
instead. That works on both styles of curses.
remote peer will be connected through. This avoids the ``Checking for
invitation on caller's machine'' problem for multi-homed hosts.
Thanks to: Garrett, for his `find_interface' example
