Refactor ChangeVarNodesExtended() using the custom callback
fc069a3a6319 implemented Self-Join Elimination (SJE) and put related logic
to ChangeVarNodes_walker(). This commit provides refactoring to remove the
SJE-related logic from ChangeVarNodes_walker() but adds a custom callback to
ChangeVarNodesExtended(), which has a chance to process a node before
ChangeVarNodes_walker(). Passing this callback to ChangeVarNodesExtended()
allows SJE-related node handling to be kept within the analyzejoins.c.
