94 old _stub packages have been removed from unstable

[Maciej (Matchek) Bliziński]

I've used Carsten's script that finds old _stub packages, and fed the
output to our safe_remove_pkg.py. It found 94 packages that could be
removed from unstable, and I did so.

Some of you will receive emails about these stubs being removed.

Please remove the definitions of these stub packages from your build recipes.

Please don't re-upload these _stub packages to the catalog!
