Introduce a new NET_RT_IFLISTL API to query the address list. It works
on extended and extensible structs if_msghdrl and ifa_msghdrl. This
will allow us to extend both the msghdrl structs and eventually if_data
in the future without breaking the ABI.
Bump __FreeBSD_version to allow ports to more easily detect the new API.
