fae19f8ced gis: Added distance querying capabilites via the distance manager method and the distance_[gt|gte|lt|lte] lookup types (works for both PostGIS and Oracle); improved Oracle query construction and fixed transform issues.

e88ce426b6 gis: LayerMapping refactor 
(1) Moved all routines into LayerMapping class (for easier subclassing) and modularized the routines.
 (2) OFTString and OFTReal OGR fields are verified w/the Django fields prior to insertion, thus avoiding invalidating a large transaction.
 (3) Added keyword options for specifying the transaction mode, not performing transformations, and status printing.
 (4) Created unit tests.
Other Changes:
 Updated `ogrinfo` for GDAL refactor and fixed an iterating bug; simplified a few lines in `geoapp` model tests.

ef32f913a0 gis: gdal: refactor of the GDAL ctypes interface 
(1) All interactions with the GDAL library take place through predefined ctypes prototypes, abstracting away error-checking.
 (2) Fixed memory leaks by properly freeing pointers allocated w/in GDAL.
 (3) Improved OFTField support, and added support for the OGR date/time fields.
 (4) Significantly improved the OGRGeometry tests.

1c7ad200c7 gis: geos: Re-factored GEOS interface. Improvements include: 
(1) All interactions with the GEOS library take place through 
     pre-defined ctypes prototypes, abstracting away return-value
     error-checking.
 (2) Mutability is now safe. Because GEOS geometry pointers are
     marked as `const` (Thanks Hobu), previous modification techniques 
     caused unpredictable instability when geometries were constructed 
     from the pointers of other geometries (e.g., a Polygon with rings 
     from another Polygon).  Geometry components are cloned first before 
     creation of the modified geometry.
 (3) Fixed memory leaks by freeing pointers from strings allocated
     in GEOS because ctypes only frees pointers allocated in Python.

Backwards-Incompatibility Notice:
 All children geometries (e.g., rings from a Polygon, geometries from a 
 collection) are now clones -- modifications will not propagate up to
 the parent geometry as before.

2694fffcc0 gis: gdal: 
(1) Added the `field_widths` and `field_precision` properties to Layer with patch from tlp.
 (2) Field definition is now passed into the Feature from the Layer.
 (3) Fixed memory leak issue with Feature not being properly deleted.
 (4) OGR_L_GetNextFeature() now used for iteration on Layer.
 (5) Added the `gdal_version`, `gdal_full_version`, and `gdal_release_date` functions.
 (6) Made all initial pointers None instead of 0.

b6c8bba5b6 gis: spatial-database compatibility and usability changes: 
(1) The SpatialRefSys and GeometryColumns models and GeometryProxy have been moved to the PostGIS backend because their functionality depends on the spatial databse.
 (2) The GeoMixin is no longer required, as all the functionality contributed by the extra instance methods has been moved to the GeometryProxy.
 (3) The `_post_create_sql` field now returns a tuple of SQL statements, instead of a string.
