Release 1.9.0

This release brings three new major features:

• a new osm2pgsql_properties table that saves command line options and reuses them on updates
• a new database middle saves raw OSM data in JSONB format and is explicitly designed to be queried by the user
• the new (and still experimental) osm2pgsql-gen adds geometry generalization to osm2pgsql (thanks @joto)

Other changes include:

• cleanup of schema handling
• tile expiry output into database tables
• a new spherical_area() function for flex config files to calculate the area of a (multi)polygon on the sphere.
• when using the new database middle, the --middle-with-nodes option allows you to store all tagged nodes in the database (with their tags and location).
• several improvements to osm2pgsql-replication to make it more flexible and better tested (thanks to @amandasaurus and @JakobMiksch)
• don't do multi-statement SQL queries to be compatible with the PgPool-II connection pooler.

Please note that this version drops support for implicit DB schema other than public. If you rely on implict user schemas or custom schema paths, you now must configure the schema to be used with the --schema option.

To compile osm2pgsql some new libraries are needed, please see the README.md for details.
