Changes for upstream 0.8.5

These changes allow upstream 0.8.5 to build. The dkms module also builds properly.

I'm currently running the full ZTS on 5.8.0-2-amd64. I'll update tomorrow with the results.

As a side remark, my email has changed.

EDIT: This is trimmed down to just the cleanup and lintian fixes, since I was apparently a bit late getting this up.
