sd-icmp6-nd: Parse ICMPv6 prefix information

System Internals / systemd - Patrik Flykt [linux.intel.com] - 27 January 2015 01:35 UTC

Save each new onlink IPv6 prefix and attach an expiry timer to it. If the prefixes overlap, take the shorter prefix and write a debug message about the event. Once the prefix is resent in a Router Advertisement, update the timer. Add a new event for the expiring prefix.

Add two helper functions, one for returning a prefix length given a Router Advertisement and the other for generic prefix matching given an IPv6 prefix and address.
