## Which issue does this PR close? None ## Rationale for this change During testing for aggregate UDFs via FFI I discovered that if we have a UDF with a nullary type signature, it cannot use the coercion functions with arguments of zero lenght. This PR adjusts for that fact. Additional testing showed that we need to implement `return_type_from_args` or some UDFs would fail. This PR implements it. ## What changes are included in this PR? In addition to the two changes above, there are some moving around of the FFI integration tests now that they're getting larger. Basically I split them into a couple of files. ## Are these changes tested? Unit test added. -- This is an automated message from the Apache Git Service.
