Some people's 6to4 routers seem to have been blowing up because of
the unlocked route caching in if_stf. Add a mutex that protects
access to cached route. This seemed to fix problems for Pekka Savola.
Nick Sayer had similar problems, and in his case completly disabling
the route cache seemed to help. Add a sysctl net.link.stf.route_cache
that can be used to turn off route caching in if_stf.
