[Tile-serving] [osm2pgsql-dev/osm2pgsql] Generalisation module: coastlines (Issue #2408)

[Sarah Hoffmann]

lonvia created an issue (osm2pgsql-dev/osm2pgsql#2408)

Currently coastline processing is done with the separate program [OSMCoastline](https://osmcode.org/osmcoastline/) or the data is simply downloaded from [osmdata.openstreetmap.de](https://osmdata.openstreetmap.de/). osm2pgsql should eventually be able to process coastlines directly from OSM data. With the new generalization framework that might just be possible.

Any solution must be able to cope with the problem that the coastline is often broken somewhere on the planet creating invalid data. That’s why this is somewhat tricky and not just a case of merging all ways tagged `natural=coastline` and creating polygons from that.
