Bug#663685: RFS: openvpn-auth-radius/2.1-4 -- updated packaging, hardening release goal

[Gergely Nagy <algernon@balabit.hu>]

I had a look at this request, but sadly, the debdiff did not apply:

$ patch -p1 <663685.debdiff
patching file debian/rules
Hunk #2 FAILED at 21.
1 out of 2 hunks FAILED -- saving rejects to file debian/rules.rej
patching file debian/control
patching file debian/changelog
patching file debian/README.source
patching file debian/copyright
patching file debian/compat
patching file debian/patches/build-with-debug-symbols

Can you upload the whole source of -4 to, say, mentors.debian.net? That
would make it a lot easier for me to grab it, and I can debdiff to -3
myself, to see the changes.
