Can be enabled by defining KERNEL_BREAKPOINTS in arch/user_debugger.h
and will provide the arch_{set,clear}_kernel_{break,watch}point()
function. Hitting a break-/watchpoint will throw the thread into KDL.
* Finally added a comment, what's the point of
i386_reinit_user_debug_after_context_switch(), since I wonder every
time I see it. Should be optimized aways soon.
