This fixes CoveragePolygonValidator to detect covering polygons with all equal segments. It does this by taking into account segment orientation. Segments with identical orientation (in normalized polygons) indicate an invalid coverage, since the parent polygons must overlap.
This also detects duplicate polygons, which allow removing the special check for this situation.
Performance is similar to the old code, and may even be improved in some situations.
