[package] base-files: introduce /lib/functions/network.sh
This file will contain common procedures to deal with network interfaces.
Initially provides network_get_ipaddr(), network_get_ipaddr6(),
network_get_subnet() and network_get_subnet6() to determine the
primary IP addresses or subnets of a given logical interface.
