Joachim Nilsson 3c4cf96bfc More cleanup. Added license blurb to top of all source files.
Remove all old $Id:$ and similar constructs, they don't provide any
additional benefit anymore.

Add configure options for toggling terminal bell and  toying with
SIGSTOP using Ctrl-Z.  Rename config option for ANSI keys to get
a consistent namespace.

Also did some work on ANSI-fication of function definitions, lot's
of that was still lingering around.
