genetlink: introduce helpers to do filtered multicast
Currently it is possible for netlink kernel user to pass custom filter function to broadcast send function netlink_broadcast_filtered(). However, this is not exposed to multicast send and to generic netlink users. Extend the api and introduce a netlink helper nlmsg_multicast_filtered() and a generic netlink helper genlmsg_multicast_netns_filtered() to allow generic netlink families to specify filter function while sending multicast messages.
