Various Debian-specific configuration changes
ssh: Enable ForwardX11Trusted, returning to earlier semantics which cause
fewer problems with existing setups (http://bugs.debian.org/237021).
ssh: Set 'SendEnv LANG LC_*' by default (http://bugs.debian.org/264024).
ssh: Enable HashKnownHosts by default to try to limit the spread of ssh
worms.
ssh: Enable GSSAPIAuthentication by default.
sshd: Enable PAM, disable ChallengeResponseAuthentication, and disable
PrintMotd.
sshd: Enable X11Forwarding.
sshd: Set 'AcceptEnv LANG LC_*' by default.
sshd: Change sftp subsystem path to /usr/lib/openssh/sftp-server.
Document all of this.
