commit 0730eb70e1035b4924f1e8edb13c4ba712298a5d
Author: Benjamin Otte <otte redhat com>

listitemfactory: Simplify
Instead of 6 vfuncs, we now have 3 and rely on the factory keeping track
of what it needs to do.
We're doing lots of dancing from one object to another here, but this
will hopefully get simpler with further commits.
