 class FloodOnlySearchJob
extends FloodSearchJob

Try sending a search to some floodfill peers, failing completely if we don't get a match from one of those peers, with no fallback to the kademlia search Exception (a semi-exception, since we still fail completely without fallback): If we don't know any floodfill peers, we ask a couple of peers at random, who will hopefully reply with some floodfill keys. We still fail without fallback, but we then spin off a job to ask that same random peer for the RouterInfos for those keys. If that job succeeds, the next search should work better. In addition, we follow the floodfill keys in the DSRM (DatabaseSearchReplyMessage) if we know less than 4 floodfills. These enhancements allow the router to bootstrap back into the network after it loses (or never had) floodfill references, as long as it knows one peer that is up.
