* eval_error.c (warn_printf): use rb_vsprintf instead so ruby specific

extensions like PRIsVALUE can be used in format strings
* eval_error.c (error_print): use warn_print_str (alias for
  rb_write_error_str) to print a string value instead of using
  RSTRING_PTR and RSTRING_LEN manually
* eval.c (setup_exception): use PRIsVALUE instead of %s and RSTRING_PTR
