ipv6: enable anycast addresses as source addresses for datagrams
This change allows to consider an anycast address valid as source address
when given via an IPV6_PKTINFO or IPV6_2292PKTINFO ancillary data item.
So, when sending a datagram with ancillary data, the unicast and anycast
addresses are handled in the same way.
- Adds ipv6_chk_acast_addr_src() to check if an anycast address is link-local
on given interface or is global.
- Uses it in ip6_datagram_send_ctl().
