String#{lines,chars,codepoints,bytes} now return an array.

* string.c (rb_str_each_line, rb_str_lines): String#lines now
  returns an array instead of an enumerator.  Passing a block is
  deprecated but still supported for backwards compatibility.
  Based on the patch by yhara. [Feature #6670]

* string.c (rb_str_each_char, rb_str_chars): Ditto for
  String#chars.

* string.c (rb_str_each_codepoint, rb_str_codepoints): Ditto for
  String#codepoints.

* string.c (rb_str_each_byte, rb_str_bytes): Ditto for
  String#bytes.

* NEWS: Add notes for the above changes.
