This change adds cleaner extension points for calculating a sales line's base price and quantity. It makes it easier to support promotions such as extra discounts or buy-two-get-one offers without changing core sales code.

With these hooks, additions like a second or third discount, or 3x2 like offers, can be made in a clean way, without rewriting functions in the core.
