When a associatedStreet relation has multiple street members
always take the closest one. Avoid geometry operations for
the frequent case that there is only one street.
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.
