Subject: Revert "Add filters for Repo, Name, Status, Version, License and
 Maintainer"

We do not really need this feature in the library, authors of software
can easily implement this for their needs and we do not have to ship all
features all people _might_ use at some point.

Keep the library KISSy.

This reverts commit 44215217da63762b36827f5ef6604c5a2ad6b73d.
