[cairo] 128-bit arithmetic

I've finished the basic binary operators (+,-,*,/,%,<<,>>) for 64 and 128
bit unsigned numbers; I suspect we'll need signed versions of at least
some of these operations. I'll see if I can't manage that in a while.
Please let me know what other operations are needed; almost any thing is
easy now that we've got a well debugged division function.
I borrowed the algorithm from GCC (but not the code, of course).
