lib: simplify interface of setsockopt_multicast_ipv4().
* sockopt.[ch] (setsockopt_ipv4_multicast): ifindex is now mandatory (all
non-ancient OSes can use it anyway), and if_addr parameter (the address
of the interface) is now gone. (setsockopt_ipv4_multicast_if):
IP_MULTICAST_IF processing moved to this new function
* ospf_network.c (ospf_if_add_allspfrouters, ospf_if_drop_allspfrouters,
ospf_if_add_alldrouters, ospf_if_drop_alldrouters, ospf_if_ipmulticast),
rip_interface.c (ipv4_multicast_join, ipv4_multicast_leave,
rip_interface_new): adapt to the new interface
