[CWEP002] introduce RQLRelationRewriter
Refactor existing RQLRewriter for later reuse of rewriting relation as specified
by CWEP002. Work is different because we simply want to replace a relation by
another rql snippet and we don't have to bother with EXISTS, subqueries and all.
This rewriter is not yet plugged into the querier.
Depends on yams 0.40 API.
