Message:

Improvements of stack and istate_get() definitions.

• Make sure each architecture has arch/stack.h in kernel.
• Make each architecture define MEM_STACK_SIZE
• istate_get() uses MEM_STACK_SIZE to allow for a greater flexibility in computing the address of the bottom of the memory stack.
• This fixes istate_get() on ia64.
