[SPARK-20728][SQL] Make ORCFileFormat configurable between sql/hive and
sql/core
## What changes were proposed in this pull request?
[SPARK-20682](https://issues.apache.org/jira/browse/SPARK-20682) is trying
to improve Apache Spark to have a new ORCFileFormat based on Apache ORC for
many reasons.
On top of that, this PR depends on SPARK-20682 and aims to provide a
configuration to choose the default ORCFileFormat from legacy `sql/hive` module
or new `sql/core` module.
For example, this configuration will affects the following operations.
```
spark.read.orc(...)
```
```
CREATE TABLE t
USING ORC
...
```
Since SPARK-20682 (#17924 and #17943) are still under review, I'm
inevitably including the dependent code. I'll update this and previous PR
according to the review result. Also, in this PR, I updated
`ParquetReadBenchmark` to help reviewers understand the state-of-the-art status
of Apache Spark.
## How was this patch tested?
Pass the Jenkins with new test suites.
