Allow mixed IPv4 and IPv6 addresses to sctp_bindx

Also allow mixed address families to bind, since the first address on
a multihomed sctp socket must be bound with bind, while the rest are
to be bound using sctp_bindx.

At least Linux supports adding address of mixing families.

Make inet_set_faddress function available also when HAVE_SCTP is not
defined, since we use it to find an address for bind to be able to mix
ipv4 and ipv6 addresses.
