This way, users who are actually trying to find a peer (not just nodes near a
key in the DHT) can find that peer, even if they aren't a DHT server and/or
aren't in anyone's routing table.
fixes#161
Note: this does mean that the DHT won't work with peer keys by default and that
the constructor signature changes. Given all the changes that'll come with the
libp2p refactor, I don't feel too bad about this.
Before, we could end up (e.g.):
1. Creating two connections (both sides connect at the same time).
2. Try to test with the first one.
3. The first connection dies.
4. Get a stream reset and think that the other side doesn't support the DHT
protocol.
We tried to fix this by checking for an EOF. Unfortunately, reset streams don't
return EOFs.
This commit also simplifies peer tracking (and saves a bit of memory).
fixes#99
First, we use Alpha instead of K as the number of peers we grab from the
routing table (as per the kademlia paper).
Second, we don't use a size limited set for the 'GetClosestPeers' query.
We're going to process more than K peers before we find the K closest
peers.
Third, Change GetClosestPeers to actually return the K Closest peers,
not a hodge podge of peers that it found on the way to finding the
closest peers.

According to golang standards, these should not be capitalized nor having a trailing period, AFAIK.
