These changes allow one to join multicast groups.

The changes are derived from #3249 that implements this feature for extmod/modlwip.c (e.g. ESP8266).

Usage stays the same and can also be tested with https://github.com/pfalcon/micropython-projs/blob/master/xiaomi-gateway-events.py (CPython, Micropython Unix, Micropython ESP8266 & Micropython ESP32).
