Comment(by nickm):
I am liking this now. I think it is good to merge. I'll give others a
day or two to look at it also.
One subtle point is that now we must only call
rep_hist_note_router_reachable() when the address of the router matches
the one in the routerinfo we have. (We do this.) If we were to call it
for addresses other than the listed address, then an attacker could do an
IP-forwarding MITM to make a node appear to be at two addresses in rapid
succession over and over, thus hammering the node's apparent uptime.
Maybe we should comment that.
