Csaba Ringhofer 86740a7d35 IMPALA-11549: Support Hive GenericUdfs that return primitive java types ...

Before this patch only the Writable* types were accepted in GenericUdfs
as return types, while some GenericUdfs in the wild return primitive java
types (e.g. Integer instead of IntWritable). For legacy Hive UDFs these
return types were already handled, so the only change needed was to
map the ObjectInspector subclasses (e.g. JavaIntObjectInspector) to the
correct JavaUdfDataType in Impala.

Testing:
- Added a subclass for TestGenericUdf (TestGenericUdfWithJavaReturnTypes)
  that returns primitive java types (probably inheriting in the opposite
  direction would be more logical, but the diff is smaller this way).
- Changed EE tests to also use TestGenericUdfWithJavaReturnTypes.
- Changed FE tests (UdfExecutorTest) to check both
  TestGenericUdfWithJavaReturnTypes and TestGenericUdf.
- Also added a test with BINARY type to UdfExecutorTest as this was
  forgotten during the original BINARY patch.
