was being interperated and displayed as ^M on the remote side.
Old curses used to change the behavior of the tty and how carriage
return was interperated via STDIN. ncurses does this on a per-window
basis within the library rather than using the tty modes. Since
talk is bypassing ncurses, it was missing the conversion.

- 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
