simplify very large polygons non used in addresses
...
Polygons with rank_address = 0 are only used in search and (rarely)
for reverse lookup. Geometries do not need to be precise for that
because topology does not matter. OSM has some very large polygons
of natural features with sizes of more than 10MB. Simplify these
polygons to keep the database and indexes smaller.

be more strict about removal from place_to_be_deleted
...
If the type of a place is changed and then the same insert issued
again, the old data will effectively remain in the table.
Fixed #3168 .

split query that deletes old objects from placex
...
placex only has partial indexes over OSM types, so the OSM type
needs to be hardcoded to ensure these indexes are used.

reorganize handling of place type changes
...
Always replace existing entries in place, never delete them because
a direct delete will cause conflicts.

change updates to handle delete/insert workflow
...
This makes Nominatim compatible with osm2pgsql's default update
modus operandi of deleting and reinserting data. Deletes are diverted
into a TODO table instead of executing them. When data is reinserted,
the corresponding entry in the TODO table is deleted. After updates are
finished, the remaining entries in the TODO table are executed, doing
the same work as the delete trigger did before.
The new behaviour also works against the gazetteer output with its
insert-only mechanism.

improve handling von updates on nodes in interpolations
...
Use the same update mechanism as for updates on the interpolations
themselves. Updates must solely happen in place_insert as this is
the place where actual changes of the data happen.

Name changes may have an effect on parenting. Don't update
surrounding rank30 objects with addr:place tags as this is
