two untested commits that should improve the situation a bit and may
completely obsolete the chdir change

preview/explicit-compute-states

Andreas Beckmann (2):
      lib/db: ensure initialization in public methods
      p-r,dwke,lib/db: add explicit compute_package_states()

some of the public methods in PackagesDB did not ensure the lazy
initialized structures they accessed were initialized - not a problem
with the current call structure, but open for failures on new features
