There is absolutely no reason for these functions to be in commpage,
they don't do anything that involves the kernel in any way.
Additionaly, this patch rewrites memset and memcpy to C++, current
implementation is quite simple (though it may perform surprisingly
well when dealing with large buffers on cpus with ermsb). Better
versions are coming soon.
