Rewrote the uIP IPv6 route handling code. Instead of being nested deeply inside the uip-ds6.c file, the route management code is now in a separate file, uip-ds6-route.c. This file presents a lib/list.h API for the routes, which makes the route list much easier to use. Additionally, the uip-ds6-route.c file adds a callback API that invokes a callback when routes are added and removed.
