lwt: Add cfg argument to build_state
Add cfg and family arguments to lwt build state functions. cfg is a void
pointer and will either be a pointer to a fib_config or fib6_config
structure. The family parameter indicates which one (either AF_INET
or AF_INET6).
LWT encpasulation implementation may use the fib configuration to build
the LWT state.
