Subject: 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.
