Split QTW_EXAMINE_RTES flag into QTW_EXAMINE_RTES_BEFORE/_AFTER. This change allows callers of query_tree_walker() to choose whether to visit an RTE before or after visiting the contents of the RTE (i.e., prefix or postfix tree order). All existing users of QTW_EXAMINE_RTES want the QTW_EXAMINE_RTES_BEFORE behavior, but an upcoming patch will want QTW_EXAMINE_RTES_AFTER, and it seems like a potentially useful change on its own.
