Major progress, multiply now almost works
...
There's a premature free() somewhere, and I'm not sure why.
Print depends on divide, which is easy, but also on mod and floor (of rationals) which isn't.

OK, my idea that long multiplication is like long addition is wrong.
...
It's still broken, but it's broken because of fundamental misunderstanding which tinkering won't solve.

Much investigation of bignum problems
...
bignum multiply is still not working, but as bignum read and bignum divide depend on it, it's the problem to hit first.

Now creating the correct internal bignum representation
...
add_integers returns an integer which by inspection of the internal representation is correct, but the print representation is not correct.

Garbage collection now much better, not good
...
There's clearly still a lot of things getting incremented but not decremented.

Fixed the eval-real test
...
So that it passes provided the answer is right to within one part in a million. Also worked on a solution to returning exceptions from make_stack_frame

Much work, all I think positive, but defun still doesn't work.
