ruby.git/string.c, branch v2_1_0_preview2

* gc.c (rb_gc_resurrect): added.

2013-11-19T09:48:47+00:00

  rb_fstring() used rb_gc_mark() to avoid freeing used string.
  However, rb_gc_mark() set mark bit *and* pushes mark_stack.
  rb_gc_resurrect() does only set mark bit if it is before sweeping.
* string.c (rb_fstring): use rb_gc_resurrect.
* internal.h: add decl.
