     Add support for an experimental zero-knowledge password authentication
     method using the J-PAKE protocol described in F. Hao, P. Ryan,
     "Password Authenticated Key Exchange by Juggling", 16th Workshop on
     Security Protocols, Cambridge, April 2008.

     This method allows password-based authentication without exposing
     the password to the server. Instead, the client and server exchange
     cryptographic proofs to demonstrate of knowledge of the password while
     revealing nothing useful to an attacker or compromised endpoint.

     This is experimental, work-in-progress code and is presently
     compiled-time disabled (turn on -DJPAKE in Makefile.inc).
