Title: Replace mrb_intern() func with mrb_intern2() or mrb_intern_cstr() func.

mrb_intern() function is backward compatibility function.
In case string is constant variable, replace mrb_intern() with mrb_intern_cstr() function.
In case string is literal text, replace mrb_intern() with mrb_intern2() function.
