Cancel fold range futures

Previously we had functions to create and wait on fold range futures, but no way
to cancel them. This commit add clauses to `cancel/1,2` to do just that.

Also, once the `?IS_FOLD_FUTURE` macro is defined, use it in a few function
heads instead of the previously used `{fold_info, _, _}` tuple.
