Fix libpayload alloc() size and gcc pointer optimization problems.

The previous commit was incomplete and missed setting the entire
    alloc area.

There are also additional problems with gcc optimizations of the
    pointer math. The "auto" casting by gcc wouldn't return warnings,
    but it was causing the optimization to be incorrect. We are now
    very explicit in the casting in the pointer math.
