This commit introduces a new field 'sublevels_up' in ReplaceVarnoContext, and enhances replace_varno_walker() to: 1) recurse into subselects with sublevels_up increased, and 2) perform the replacement only when varlevelsup is equal to sublevels_up. This commit also fixes some outdated comments. And besides adding relevant test cases, it makes some unification over existing SJE test cases.
