[Savannah-hackers-public] New sshd configuration

[Bob Proulx]

Hackers,

FYI...  I am going to change the sshd configuration to avoid the
dependency even of root logging in that the database is available.

  AuthorizedKeysCommandUser root
  Match User root
          AuthorizedKeysCommand /bin/true
  Match all
          AuthorizedKeysCommand /root/bin/sv_get_authorized_keys

I have tested that locally.  Seems to do the desired thing.  And that
was what prevented me from being able to log in after a reboot
previously.  I am deploying it on vcs0.
