* IP detection revised for full IPv4 / IPv6 support
*
*
* In general, each interface (Wifi/Eth) can have 1x IPv4 and
* 2x IPv6 (Global routable address and Link-Local starting witn fe80:...)
*
*
* We always use an IPv4 address if one is assigned, and revert to
* IPv6 only on networks that are v6 only.
* Ethernet calls can be safely used even if the USE_ETHERNET is not enabled
*
*
* New APIs:
* - general form is:
* `bool XXXGetIPYYY(IPAddress*)` returns `true` if the address exists and copies the address
* if the pointer is non-null.
* `bool XXXHasIPYYY()` same as above but only returns `true` or `false`
* `String XXXGetIPYYYStr()` returns the IP as a `String` or empty `String` if none
*
*
* `XXX` can be `Wifi` or `Eth`
* `YYY` can be `` for any address, `v6` for IPv6 global address or `v6LinkLocal` for Link-local
*
*
* - Legacy `Wifi.localIP()` and `ETH.localIP()` always return IPv4 and nothing on IPv6 only networks
*
* - v4/v6:
* `WifiGetIP`, `WifiGetIPStr`, `WifiHasIP`: get preferred v4/v6 address for Wifi
* `EthernetGetIP`, `EthernetGetIPStr`, `EthernetHasIP`: get preferred v4/v6 for Ethernet
*
*
* - Main IP to be used dual stack v4/v6
* `hasIP`, `IPGetListeningAddress`, `IPGetListeningAddressStr`: any IP to listen to for Web Server
* IPv4 is always preferred, and Eth is preferred over Wifi.
* `IPForUrl`: converts v4/v6 to use in URL, enclosing v6 in []
*
*
* - v6 only:
* `WifiGetIPv6`, `WifiGetIPv6Str`, `WifiHasIPv6`
* `WifiGetIPv6LinkLocal`, `WifiGetIPv6LinkLocalStr`
