Split length from perimeter calculation in geometry API, as returning perimeter for length for polygons is misleading and results in incorrect length/perimeter calculations for mixed geometry collections. Enable length & perimeter unit tests against reference geometries. Now the length & perimeter values match those calculated by PostGIS.
