62b60c70e6 reverse on street level should compute distance to object 
The centroid of a building may be far away even when still inside
the building.

ed85388de5 fix address walk-up for reverse 
Fixes the row for the join and completely drops parts that have
a linked_place_id.

8d91a88b22 allow unnamed roads for reverse geocoding 
Should avoid that results are too far off in areas where
most roads are unnamed.

adbbb1ce02 restrict number of results for reverse queries 
When given a coordinate off the coast of a large town, the entire
town may end up in the potential results during the reverse query.
Postgres then needs to sort tens of thousands of results before it
can determine the clostest one. Given that the results at such a
large search radius are bound to be imprecise anyway, restrict
the number of results postgres should consider to 1000.

1424e8e29b use Result class in reverse geocoding 
Also simplifies the reverse algorithm slightly by no longer
having an additional distance lookup.

30511fd3ab replace NearPoint with a more generic context object 
The NearPoint is actually common to all SearchDescriptions
and there is other context data as well. like viewbox, that
needs to be available to the search object but is common.

c8e79397f5 introduce address column for place tables 
The column is a hstore containing the full OSM tag with key and
value.

c48fb88e6b move interpolaton computation into indexing step 
The interpolaton computation needs information from the osm2pgsql
slim tables which may not be available when the data is inserted.

Insertion now only adds a line with basic address information to
location_property_osmline. The line is then split during the
indexing, leading to more lines (which are complete in that case)
being inserted.

Fixes #598.

a84a7a70f3 reverse: choose interpolation only when further than point

b8db8301df reverse: reduce search radius for interpolations 
Interpolations should have the same maximum search radius as
address points. Change search strategy and only search for
interpolations either before decreasing the maxRank to road
or when a POI was found and we need to check that there isn't
an interpolation that is closer.

a855ffe58e replace deprecated postgis functions

spelling in newer version and throw a deprecation warning.
