Michael Stapelberg c857ec6218 turn banner (printed before auth) into MOTD (printed after login)
This means the message will be printed only once when using the breakglass
command line tool (which first copies over a tarball, then logs in).

Also switch to fancy ASCII art while we’re at it :)

Michael Stapelberg ef69007a43 use renameio to avoid “text file busy” errors
Before this commit, extracting a breakglass would fail when /tmp/breakglass*/sh
was busy because it was being run in a separate connection.

Michael Stapelberg 564a0eceaf explicitly set TMPDIR
programs such as podman will otherwise default to /var/tmp

Michael Stapelberg 629a19f92d breakglass command: add -proxy flag for easier ProxyCommand usage
Now you can use the following in your ~/.ssh/config for example:

Host scan2drive-backup
	Hostname scan2drive.lan
	IdentityFile ~/.ssh/id_ed25519_scan2drivebackup
	ProxyCommand breakglass -proxy scan2drive.lan

Michael Stapelberg 0a14bc7f0c set HOME=/perm/home for persistent configs in interactive usage
As a welcome side effect, this enables persistent shell history by default!

Now that the host key is created automatically, this allows using breakglass
without ever creating or modifying a permanent partition.

Michael Stapelberg 83d59cddd7 recommend ed25519 host keys
Newer OpenSSH versions seem to have problems with (some?) older ssh-rsa keys,
so I figured we could switch to ed25519 and avoid any confusion regarding
ssh-rsa support.

Michael Stapelberg 33834ea6fa allow overwriting the gokrazy URL prefix
The special syntax :1080 means “use the default, but force port to 1080”,
which is useful when you are running the gokrazy web interface on a different
port because you need port 80 for your web appliance.

Michael Stapelberg 9eab5f8b0d add -prepare and -ssh_config flags for usage in SSH ProxyCommand
