Brian Somers 58330d7bfa When resending chap challenges, resend the same challenge
each time rather than making up a new one.

Increase the authname/authkey max sizes to 100 characters.

Allow ``authkey'' specifications beginning with ``!''.
When a challenge is received, the text following the
``!'' is executed as a program (expanding stuff in the same
way that ``sh'' and ``!bg'' do).  The program is passed the
peer name, peer challenge and local ``authname'' on standard
input and is expected to output the name/key combination that
should be used to build the CHAP response.

This provides support for Secure ID cards (guess what I was
given at work recently!) using CHAP.

Examples will follow.
