improved DHT get_peers code. get_peers always returns nodes now, and announce_peer is always sent to the k closest nodes to the info-hash. This should significantly speed up retrieving peers from the DHT

libtorrent implements a few extensions to the Mainline DHT protocol.
get_peers response
------------------
libtorrent always responds with ``nodes`` to a get_peers request. If it has
peers for the specified info-hash, it will return ``values`` as well. This is
because just because some peer announced to us, doesn't mean that we are
among the 8 closest nodes of the info hash. libtorrent also keeps traversing
nodes using get_peers until it has found the 8 closest ones, and then announces
to those nodes.
