This commit: - switches between static IP and DHCP based on the presence of the "uplink_ipv4" config value. - makes reading the configuration more robust against missing values. By frequently refreshing its DHCP lease, TunSpace stresses DHCP servers with faulty configurations. For example, Telekom Speedport modems completely lock up and permanently stop handing out DHCP leases to clients. Another example is a DHCP server that always hands out new IP addresses, even though TunSpace only requests a renew of its existing IP address, which leads to fast exhaustion of the address pool.
Bird, OLSR and Babel spam syslog if the wireguard interface doesn't
have its private key configured yet. Prevent this by bringing the
interface up later, once it's fully configured.
