One of the changes coming with Arduino 3.x is that the lwip headers are no longer included by one of the upstream dependencies, resulting in there not being defines for things like IPADDR_NONE and IPADDR_LOOPBACK. This conditionally adds those defines.
An alternative implementation would be to do #include <ip4_addr.h> in LCBUrl.cpp where I have included the conditional defines.
