Merge branch 'patch-5' of https://github.com/lgierth/cjdns into crashey
Some cleanup, mainly to the Janitor. Moved most of the identical code for getPeers-ing from different rumormills into one function. Rewrite the keyspace maintenance code to add important addresses to a rumormill so it can ping the relevant nodes (or do a search) later. Sends fewer searches but more pings. Expect about the same number of packets per minute as before for the current network, can potentially increase slightly (logarithmically up to a maximum of ~2x what we used before) as the network grows.
