record package metadata that describes co-installability

Specifically all entries in the Conflicts header are saved in the
conflict table, all entries in the Provides header are saved in the
provide table (to cover conflicts with virtual packages) and packages
using dpkg-divert in preinst get a magic "_dpkg-divert" entry in their
conflict table. With this metadata it should be possible to compute
undeclared file conflicts.
