sd-network: IPv4 link-local support [v2]

System Internals / systemd - Umut Tezduyar Lindskog [axis.com] - 3 March 2014 16:24 UTC

Implements IPv4LL with respect to RFC 3927 (http://tools.ietf.org/rfc/rfc3927.txt) and integrates it with networkd. Majority of the IPv4LL state machine is taken from avahi (http://avahi.org/) project's autoip.

IPv4LL can be enabled by IPv4LL=yes under [Network] section of .network file.

IPv4LL works independent of DHCP but if DHCP lease is aquired, then LL address will be dropped.

[tomegun: removed a trailing newline and a compiler warning]
