david gauchard 324b3f9678 IPAddress updates (#5409) ...

* restore definition of ip_addr (=ipv4_addr) when IPv6 is not enabled

* overload IPAddress:operator == and != to avoid ambiguousness

* brings lwIP's INADDR_NONE (which is IPv4 255.255.255.255, suposed to be invalid address but it is)

* inet_aton is a lwIP define, rename Ethernet DNS implementation of this to prevent name collision
that's because IPAddress now includes lwip/inet.h
