kernel - Increase UPAGES, add kernel stack guard page
* Increase UPAGES from 3 to 4. This is the kernel thread stack size.
* Add infrastructure to make it possible to allocate a guard page along
with a kmem allocation and use it when allocating kernel thread stacks.
The first page of stacks allocated this way will be non-accessible
(hence the increase in UPAGES).
