Convert the '_place_*' entries back to normal entries before
returning them in the 'namedetails' section. If the name field is
duplicated, kept the '_place_*' notation. This preserves the previous
behaviour before _place_ names were introduces but adds the additional
names from the linked place for reference.
These tables have never been actively maintained and the code is
completely untested. With the upcomming changes, it is unlikely
that the code remains usable.
This removes the aux tables and all code that references them.
