This is prompted by a number of factors:

* It was more useful back in the dial-up days, but no-one uses dial-up
  any more

* In many cases there will be no terminal accessible to the prompter
  program at the point where the prompter is run

* The passwordfd plugin does much the same thing but does it more
  cleanly and securely

* The handling of privileges and file descriptors needs to be audited
  thoroughly.

This is associated with the passprompt plugin, and like it, seems not
to be very useful any more now that no-one uses dial-up.  Also, its
function seems somewhat peripheral to PPP.

This removes various scripts and config files that related to dial-up
connections, doing PPP over rsh or ssh (for which there are better
alternatives), and updating resolv.conf (for which distros have other
mechanisms these days).

The commentary and example in this file doesn't seem all that useful.
