Log:
  Use the __result_use_check attribute also for reallocf(3).
  
  The GCC attribute causes a warning to be emitted if a caller of the
  function with this attribute does not use its return value. Unlike the
  traditional realloc, with reallocf(3) we don't have to check for NULL
  values but we still have to make sure the result is used.
