This commit implements Sections 4.1.2 and Section 4.2 of https://tools.ietf.org/html/draft-gont-6man-slaac-renum-05
It caps the Preferred Lifetime of PIOs to the "Router Lifetime" value present in the Router Advertisement Message, and the Valid Lifetime to 48 * Router Lifetime.
It honors PIO Valid Lifetimes < 2 hours, deviating from item "e)" (pp. 19-20) of Section 5.5.3 of RFC4862, to allow for timilier reaction to renumbering events.
Additionally, it also caps the Valid Lifetime of RIOs to "Router Lifetime".
