Fix WeakRef finalize

* array.c (rb_ary_delete_same_obj): new function for WeakRef.
  This deletes same objects as item argument in the array.

* internal.h (rb_ary_delete_same_obj): add a declaration.

* gc.c (wmap_final_func): remove WeakRef object reference from the
  array. rb_ary_delete() is not usable because it uses rb_equal() to
  compare object references.

* gc.c (wmap_finalize): remove recycled object references from weak
  map hash properly. How to get object reference from object id was
  wrong. st_delete() doesn't work properly if key and value arguments
  are same. The key of obj2wmap is referenced object and the value of
  obj2wmap is WeakRef array.

* gc.c (wmap_aset): obj2wmap should contain WeakRef array in the
  definition.

* test/test_weakref.rb
  (TestWeakRef#test_not_reference_different_object,
   TestWeakRef#test_weakref_finalize): add tests for above.

gc.c: refactoring to rename variables

* gc.c (wmap_final_func): rename variables to clarify the meaning.
  In wmap2obj the key is WeakRef and the value is referenced object.
  In obj2wmap the key is referenced object and the value is an array
  of WeakRef.

* gc.c (wmap_finalize): ditto.

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.

* array.c (ary_resize_smaller): new function to resize array.
