Mynacol 8ab0652af8 Generate and use temporary IPv6 addresses
Temporary addresses are privacy-preserving for outgoing traffic, as they
don't disclose the MAC address.
See also https://blog.apnic.net/2022/06/10/iot-devices-endanger-ipv6-privacy/

The MAC-derived IPv6 stays, so clients (e.g. IP-based remotes) have a
permanent IPv6 as before.
Servers, including local ones, will see changing IPv6 addresses when
contacted by LibreELEC. Users who don't like this may revert this
setting.
