This commit significantly increases test coverage of geo_ops.c, adding tests for various issues addressed by 2e2a392de3 (which went undetected for a long time, at least partially due to not being covered). This also removes alternative results expecting -0 on some platforms. Instead the functions are should return the same results everywhere, transforming -0 to 0 if needed. The tests are added to geometric.sql file, sorted by the left hand side of the operators. There are many cross datatype operators, so this seems like the best solution.
