Peter Bindels 85c2ad94d5 LibC: Make scanf always copy its va_list ...

On x86_64 GCC implements va_list as an array. This makes the syntax
for taking a pointer to it break & crash. The workaround / solution is
to create a copy. Since va_list is a tiny struct referencing the
actual varargs, this is little overhead (especially compared to
va_args itself)
