* 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.

Fixed #8462 -- Made `length` and `length_is` template filters fail silently when given a value that has undefined length and added tests for both filters.  Based on patch from marcelor, rob, and SmileyChris.

This is backwards-incompatible if you were doing things to 'initial' in BaseModelFormSet.__init__, or if you relied on the internal _total_form_count or _initial_form_count attributes of BaseFormSet. Those attributes are now public methods.

Some minor tweaks to the admin changelist styles for the new action menus. Cut out extranous margins around checkboxes on changelists and styled the action row to stack better with the date hierarchy browser.

In the future, I'd like to fix this properly, but the current behavior
has the advantage of being consistent across the board (and changing it
everywhere is backwards-incompatible with documented functionality).

This was the (undocumented) behaviour prior to r10118 and now it's back
again. It's neither hard nor harmful to maintain compatibility with the
old ways.
