This feature is propsoed in [DSIP-1](https://cwiki.apache.org/confluence/display/DORIS/DSIP-001%3A+Java+UDF). This PR support fixed-length input and output Java UDF. Phase I in DIP-1 is done after this PR. To support Java UDF effeciently, I use no data copy in JNI call and all compute operations are off-heap in Java. To achieve that, I use a UdfExecutor instead. For users, a UDF class must have a public evaluate method.
