Enable to call dynamic link functions from tx or query directly

Now, dynamic link functions can be called by only other contracts. Enable it from tx or query directly.

without #255, read-only dynamic linked functions can be called via tx. Consider that it is ok or should be solved.

I think it is unnecessary. I think it's enough the callee function for dynamic link only be called by dynamic link caller.
