Fix building with Asio 1.33.0 or newer

Asio 1.11.0

- Conversion between IP address types, and conversion from string to
  address, is now supported via the address_cast<>(), make_address(),
  make_address_v4() and make_address_v6() free functions. The from_string(),
  to_v4(), to_v6() and v4_mapped() member functions have been deprecated.
