Complete re-write of the sql.ReWrite()
which is crap code.
Goals:
- Allow sql.ReWrite to support push-down to different data sources when using multi-source queries (joins, select where in, etc).
- Allow poly-fill missing feautures (ie, group-by in cassandra) but support partial push-down.
- Allow function re-write (ie, postgres, mysql, etc have different names for the same functions). Allow a dialect-writer to support function re-write.

plan
- much better unit tests on the sql-rewrite, and more component oriented
- allow function or node-level rewrite for different dialects
