kernel: apply uintptr for ulong when a pointer is stored
this change is in preparation for amd64. the systab calling convention was also changed to return uintptr (as segattach returns a pointer) and the arguments are now passed as va_list which handles amd64 arguments properly (all arguments are passed in 64bit quantities on the stack, tho the upper part will not be initialized when the element is smaller than 8 bytes). this is partial. xalloc needs to be converted in the future.
