> Attachments: HIVE-521-all-v1.patch, HIVE-521-all-v2.patch,

> See HIVE-511 for an example of the move.
> size, if, isnull, isnotnull are all implemented with UDF but they are
> actually working on variable types of objects. We should move them to
> GenericUDF for better type handling.
> This also helps to clean up the hack in doing type matching/type conversion
> in UDF.
