DRILL-4048: Fix reading required dictionary encoded varbinary data in parquet files after recent update

Fix was small, this update is a little larger than necessary because I was hoping to create

a unit test by modifying the one I had added in the earlier patch with the version upgrade.

Unfortunately we don't have a good way to generate Parquet files with required columns from

unit tests right now. So I just added a smaller subset of the binary file that was posted on

the JIRA issue. The refactoring of the earlier test was still useful for readability,

so I kept it in.

Add synchronization to DrillBuf.retain() to avoid contention issues.

Add assertion around QueryDataBatch release to ensure that we're not releasing the buffers twice.
