[3/3] drill git commit: DRILL-3151: Fix many ResultSetMetaData method return values.

Posted by me...@apache.org.
DRILL-3151: Fix many ResultSetMetaData method return values.

Added ~unit test for ResultSetMetaData implementation.

Made getObject return classes available to implementation of getColumnClassName:
- Added SqlAccessor.getObjectClass() (to put that metadata right next to code
  to which it corresponds rather than in far-away parallel code).
- Added similar AvaticaDrillSqlAccessor.getObjectClass().
- Changed DrillAccessorList.accessors from Accessor[] to
  AvaticaDrillSqlAccessor[] for better access to JDBC getObject return class.
- Extracted return classes from accessors to pass to updateColumnMetaData.

Reworked some data type mapping and utilities:
- Added Added Types.getSqlTypeName(...).
- Renamed Types.getJdbcType(...) to getJdbcTypeCode(...)
- Replaced Types.isUnSigned with isJdbcSignedType.
- Fixed various bogus RPC-type XXX -> java.sql.Types.SMALLINT mappings.
- Removed DrillColumnMetaDataList.getJdbcTypeName.
- Moved getAvaticaType up (for bottom-up order).
- Revised DrillColumnMetaDataList.getAvaticaType(...).

MAIN:
- Updated updateColumnMetaData(...) to change many calculations of metadata
  input to ColumnMetaData construction.  [DrillColumnMetaDataList]

Updated other metadata tests per changes.
