Sometimes binding to local IP just doesn't work (for example raspberry pi wlan0). Also, when DHCP IP changes, the program would have to update local IPv4 and IPv6. Solution to that is binding to an interface name, which does not change.

This PR adds interface/device binding just like in curl:
$ curl --interface wlan0 'https://api.ipify.org' 1.2.3.4It's needed, because sometimes binding to local IP just doesn't work (for example raspberry pi wlan0).
Also, when DHCP IP changes, the program would have to update local IPv4 and IPv6.
Solution to that is binding to an interface name, which does not change.
Also, I've added a small fix for IPv6 which was I've found a few months ago - it was kinda annoying to debug on an IPv6 machine.
Unfortunatelly, 536b3a8 wasn't tested. As I remember there's something wrong with IP v4/v6 handling... not sure if that's IPv6 -> IPv4.
