Description

Grepping the code for 0.17, 0.18, and 0.19, there are lots of tweaks which were applied to keep the code compatible with these Hadoop versions. As of HIVE-1701, we're dropping support for them, so we should clean up by eliminating the tweaks.

Likewise, we can scrub away any shim interface methods which were only needed for these versions (i.e. most of them).
