Add functions to join/leave IGMP group by netif

Browse Source 
Existing functions are based on IP address, but the address is used
only to look up which netif to act on. The netif-based core code is
extracted to new exported functions.

If you have a netif handle, this makes it easier to join/leave
groups, without the need to convert to IP address first only for the
IGMP code to convert back to netif.
