dtucker@openbsd.org 88057eb6df upstream: Add ModuliFile keyword to sshd_config to specify the
location of the "moduli" file containing the groups for DH-GEX.  This will
allow us to run tests against arbitrary moduli files without having to
install them. ok djm@

     First rough implementation of the diffie-hellman group exchange.  The
     client can ask the server for bigger groups to perform the diffie-hellman
     in, thus increasing the attack complexity when using ciphers with longer
     keys.  University of Windsor provided network, T the company.
