This is needed for pedestrian areas mapped as multipolygons
and consequently as relations. The lookup in placex guarantees
that the referenced OSM object is indeed a street.
Fixes#2669.
The inherited housenumber is needed for display output. We can't
take the one from the housenumber field because it is already
normalized. Remove the inherited address only when reindexing.
Fixes#2683.
If an addr:place is given but no addr:street tag, then bind
the rank 30 object always to a <=25 object, even when there
is none found with the same name.
Squares are now addressable (on address level 25) and thus can
be attached to a house number via addr:place. Needed to increase
the rank range for matching up addr:place to 25.
