DRILL-2769: Fix most non-SQLException not-supported-yet exceptions.
Core:
Added (auto-scanning) unit test. [Drill2769UnsupportedReportsUseSqlExceptionTest]
Added translation of lots of UnsupportedOperationExceptions (and some
RuntimeExceptions) from Avatica code to SQLFeatureNotSupportedExceptions (tons
of method overrides).
Also:
Added explicit bounds checks in ResultSetMetaData methods and checking of
last-accessed column in DrillAccessorList.wasNull() (to fix other
RuntimeExceptions to SQLExceptions).
Added resetting of last-accessed column to fix latent bug in DrillAccessorList.
Hygiene:
- Renamed some zero-based index/ordinal-position parameters to "...Offset".
- Renamed some one-based index/ordinal-position parameters to "...Number".
- Renamed DrillAccessorList lastColumn to rowLastColumnOffset; declared
explicit logical null value for rowLastColumnOffset.
