523463a3a2 upstream commit
Revise hostkeys@openssh.com hostkey learning extension.

The client will not ask the server to prove ownership of the private
halves of any hitherto-unseen hostkeys it offers to the client.

Allow UpdateHostKeys option to take an 'ask' argument to let the
user manually review keys offered.

     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).

     "just commit it.  It isn't too intrusive." deraadt@

     makes the pain stop in one easy step
     NB. portable commit contains everything *except* removing includes.h, as
     that will take a fair bit more work as we move headers that are required
     for portability workarounds to defines.h. (also, this step wasn't "easy")
