net: Export IGMP/MLD message validation code
With this patch, the IGMP and MLD message validation functions are moved from the bridge code to IPv4/IPv6 multicast files. Some small refactoring was done to enhance readibility and to iron out some differences in behaviour between the IGMP and MLD parsing code (e.g. the skb-cloning of MLD messages is now only done if necessary, just like the IGMP part always did). Finally, these IGMP and MLD message validation functions are exported so that not only the bridge can use it but batman-adv later, too.
