Subject: [PATCH] =?UTF-8?q?ssh=5Ffilter=5Fbtrbk.sh:=20replace=20OpenSSH?=

OpenSSH’s environment variable `SSH_CLIENT` has been deprecated in upstream
commit f37e246f858cdd79be4f4e158b7b04778d1cb7e9 (2002-09-19) and replaced by
`SSH_CONNECTION`.

Both contain more than just the remote information, thus adapted the log message
to reflect that.

Since this might be used by 3rd-party programs (like fail2ban), added a specific
note to the changelog.
