Add RTM_NEWADDR and RTM_DELADDR netlink messages with family

Added AF_UNSPEC GETADDR function to allow the netlink notifications
to be replayed to avoid loss of state due to application start
ordering or restart.

RTM_NEWADDR and RTM_DELADDR are not used to add these entries to the kernel.
so, it seems a bit wrong to use RTM_NEWADDR and RTM_DELADDR to notify them to
userspace and also to request a special dump of these addresses.

This could just be a new nested netlink attribute in the existing link dump ?
