[SPARK-12362][SQL][WIP] Inline Hive Parser
This PR inlines the Hive SQL parser in Spark SQL.
The previous (merged) incarnation of this PR passed all tests, but had and
still has problems with the build. These problems are caused by a the fact that
- for some reason - in some cases the ANTLR generated code is not included in
the compilation fase.
This PR is a WIP and should not be merged until we have sorted out the
build issues.

[SPARK-12363] [SQL] Inline Hive parser into spark sql.
This is a WIP. This inlines the hive sql grammar parser into spark sql in
the hive
subproject. This should eventually be moved into the SQL core project once
all the
hive dependencies are removed.
This patch does some of that by cleaning up the hive code to remove much of
semantic
analysis.
