* array.c (rb_ary_slice_bang): Be consistent with Array#slice()

and String#slice!().  Just return nil when a negative length or
  out of boundary index is given instead of raising an exception
  via internal functions.
  (rb_ary_slice_bang): should not use rb_ary_subseq() which shares
  internal pointer.  splice modifies the receiver right after
  subseq.  [ruby-dev:34005]
  (rb_ary_slice_bang): should adjust length before making
  sub-array.

* enumerator.c (Init_Enumerator): Override
  Enumerable::Enumerator#each_with_index with #with_index.
