We shouldn't be doing these crazy things.
The only usage of this is the NextID rule which computes an unique
number by incrementing a variable. This is used for example to generate
names for the extra files used in xattr emulation.
But we certainly don't need multiplication, division, etc. That's better
done in scripts (Python, for example) in rule actions. So keep just
enough of this for NextID to work, and we could probably make it even
simpler.

operate manually on digit lists, so they are certainly not fast and shouldn't
be used excessively, but at least it's possible to do calculations in Jam now,
should the need arise.
