[FLINK-1710] [table] Switch compile backend to Janino
This greatly reduces compile time while still supporting the same
feature set.
I added Janino in flink-bin/LICENSE and flink-bin/NOTICE. I hope this is
correct. Can someone comment on this?

> Key: FLINK-1710
> URL: https://issues.apache.org/jira/browse/FLINK-1710
> Project: Flink
> Issue Type: Bug
> Components: Expression API
> Affects Versions: 0.9
> Reporter: Stephan Ewen
> Assignee: Aljoscha Krettek
> Fix For: 0.9
>
>
> The tests of the Expression API take an immense amount of time, compared to
> the other API tests.
> Is that because they execute on large (generated) data sets, because the
> program compilation overhead is high, or because there is an inefficiency in
> the execution still?
