ST_contains, ST_containsProperly, ST_covers, and ST_intersects are now overloaded.
The new arguments style is ( geometry, geometry, integer). The third argument is used to determine when the first argument changes. The assumption is that when the third argument changes, the first argument is assumed to have changed too. This side-steps the issue of determining when the identity of the first geometry changes.

The tests were copied from regress_ogc, and modified.
Most of the tests use a pattern where the same function is invoked three times with the same argument.
This tests the prepared geometry caching mechanism.
This testfile haven't been added to regress/Makefile yet, as it fails for one case. This
probably due to a bug in GEOS.
