Alex Behm 025fd3bd7f IMPALA-3646: Handle corrupt RLE literal or repeat counts of 0.

Adds handling and testing for a specific Parquet data corruption
scenario with plain dictionary encoded values.

The problematic scenario is when the repeat or literal count of
the RLE-encoded dictionary indexes is decoded as 0 - an invalid value.

There are several other cases of data corruption that are not yet
handled gracefully. This patch only handles one specific case.

This directory contains Impala test workloads. The directory layout for the workloads should follow:

workloads/
   <data set name>/<data set name>_dimensions.csv  <- The test dimension file
   <data set name>/<data set name>_core.csv  <- A test vector file
   <data set name>/<data set name>_pairwise.csv
   <data set name>/<data set name>_exhaustive.csv
   <data set name>/queries/<query test>.test <- The queries for this workload
