Semantics of inner_product_single have also been changed to contain the final right shift and saturation so it can also be implemented in the optimal way for the used platform. This change affects fixed point calculations only. I also added a new fixed point macro SATURATE32PSHR(x, shift, a). It does pretty much the same thing as SATURATE32(PSHR32(x, shift), a), but it avoids over flowing in rounding up phase in the rare occasion where x has already been saturated. It should also be slightly faster.
