put in the support for 'router twins'

Browse Source 
basically, a twin is a router which is different except it shares
the same keypair. so in cases where we want to find a "next router"
and all we really care is that it can decrypt the next onion layer,
then a twin is just as good.

we still need to decide how to mark twins in the routerinfo_t and in
the routers config file.
