[OSM-dev] New osm2pgsql release

[Paul Norman]

I've tagged a new osm2pgsql release, 0.87.1. This is using the new C++ 
code, and the main changes are bugfixes, better documentation of the new 
multi-backend, and conversion of legacy C code to cleaner C++ code.

There is now documentation on the multi backend at 
https://github.com/openstreetmap/osm2pgsql/blob/master/docs/multi.md

The osm2pgsql codebase is available at
