TAJO-2052: Upgrading ORC reader version
Code is refined, and it is based on presto-orc-0.132.
* Base data structure is changed from Vector to Block.
* Some bugs are fixed.
* Compatibility with Hive is improved.
* Unluckily, there is no speed improvement.

> Upgrading ORC reader version
> ----------------------------
>
> Key: TAJO-2052
> URL: https://issues.apache.org/jira/browse/TAJO-2052
> Project: Tajo
> Issue Type: Improvement
> Components: Storage
> Affects Versions: 0.11.0
> Reporter: Jongyoung Park
> Assignee: Jongyoung Park
> Priority: Minor
>
> Currently Tajo uses presto-orc-0.86, but it was old version even when it was integrated because Presto was using JDK 1.8 at that time.
> Now that Tajo is based on JDK 1.8, it can be upgraded to a recent version 0.132.
> It becomes more robust and some minor features are added.
> Additionally hive compatibility is improved, so upgrading is necessary to support Hive-catalog.
