b69c162c9f Add base QueryException class 
Summary:
Also, inherit `TypedValueException` from `BasicException` instead of
`StacktraceException`.

This is meant as a basic API change, so that catching query exceptions becomes
simpler. The error message can be obtained from `what` method, inherited from
`BasicException`. In the future, we may extend the `QueryException`. It could
take column/row position in query source, as well as other information. Then
provide (or override `what`) a method to format the error message nicely for
the user.
