seq_iter: null list object if rewind not needed.
* lib.c (seq_iter_init_with_info): Take new Boolean argument
indicating whether the iterator needs to support the rewind
operation. If this is false, and the object is a list, then we
clobber the object, in order to eliminate the GC root.
(seq_iter_init, iter_begin, iter_reset): Pass 0 for the new
Boolean parameter.
(seq_iter_init_with_rewind): New function.
(diff, isec): Use seq_iter_init_with_rewind to request an
iterator with rewind support for the second sequence.
