- IPv4 now assumes the addresses it is supplied in send_routed_data are already the appropriate ones.
- made the Data(), operator* and operator-> methods in NetBufferFieldReader const so we can use them in the same expression as the constructor.
- fixed an issue with UDP where the wrong source address could be used in the calculating the checksum.
- changed ipv4_print_address to use the more common 0.0.0.0 format.
