The only plugins remaining are those that haven't been ported to Meson yet, and msdk. Also, the tests are still automagic. https://bugzilla.gnome.org/show_bug.cgi?id=795107

Note that I only support lilv 0.22+ for now, because it's simple and old enough. If anyone needs to use the 0.16 support it will need to be added.
