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.
