[PATCH 2/4] kernel32: Forward SetCachedSigningLevel to kernelbase.

[Mohamad Al-Jaf]

Hi Chip,

Thanks for the detailed explanation, I think I understand the difference
between the two now. But how do you determine if a function should be
forwarded or imported? Is there a way to find out for certain? So
for SetCachedSigningLevel, how can I know if it's better to forward it or
import it?
