Message:

fix #23599: Error opening osm.pbf if way has negative ID or incomplete metadata
This fixes

• handling of visible flag as proposed by *Martin*
• handling of completely missing denseinfo (ids are always delta encoded), upload is discouraged
• handling of denseinfo which only contains version data

• trunk/src/org/openstreetmap/josm/io/OsmPbfReader.java (modified) (11 diffs)
