Justin Bronn 867e71501c Refactored and cleaned up parts of the spatial database backend. Changes include: ... * Laid foundations for SpatiaLite support in `GeoQuerySet`, `GeoWhereNode` and the tests. * Added the `Collect` aggregate for PostGIS (still needs tests). * Oracle now goes to 11. * The backend-specific `SpatialRefSys` and `GeometryColumns` models are now attributes of `SpatialBackend`. * Renamed `GeometryField` attributes to be public that were private (e.g., `_srid` -> `srid` and `_geom` -> `geom_type`). * Renamed `create_test_db` to `create_test_spatial_db`. * Removed the legacy classes `GeoMixin` and `GeoQ`. * Removed evil `\` from spatial backend fields. * Moved shapefile data from `tests/layermap` to `tests/data`. Fixed #9794. Refs #9686. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10197 bcc190cf-cafb-0310-a4f2-bffc1f526a37		2009-03-30 17:15:49 +00:00
