networkd: add a basic network daemon
This daemon listens for and configures network devices tagged with 'systemd-networkd'. By default, no devices are tagged so this daemon can safely run in parallel with existing network daemons/scripts. Networks are configured in /etc/systemd/network/*.network. The first .network file that matches a given link is applied. The matching logic is similar to the one for .link files, but additionally supports matching on interface name. The mid-term aim is to provide an alternative to ad-hoc scripts currently used in initrd's and for wired setups that don't change much (e.g., as seen on servers/and some embedded systems). Currently, static addresses and a gateway can be configured. Example .network file: [Match] Name=wlp2s0 [Network] Description=My Network Gateway=192.168.1.1 Address=192.168.1.23/24 Address=fe80::9aee:94ff:fe3f:c618/64
