    Simplify stream-unfolds further, based on Mark H. Weaver's feedback.
    
    * module/srfi/srfi-41.scm (stream-unfolds): Don't use a promise to
      hold the result of the generator call. Originally I did that to
      avoid calling the generator more times than necessary, but Mark
      demonstrated that this code simplification doesn't affect that.

    Rewrite stream-unfolds based on Mark H. Weaver's feedback.
    
    * module/srfi/srfi-41.scm (stream-unfolds): Rewrite to use a
      generator stream approach, like the reference implementation,
      so we can avoid any mutation. Also just implement the SRFI's
      interface, and not the #:normal stuff. (Multiple-item returns
      are still implemented, and do not incur additional cost for
      single-item returns.)
    * test-suite/tests/srfi-41.test (stream-unfolds): Adapt the tests
      not to use #:normal any more, and change the multiple-item test
      to return non-identical multiple items, so that we can test that
      the items come back in the correct order.
