this is a major refactor of the entire codebase
it changes the monolithic peer.Peer into using
a peer.ID and a peer.Peerstore.

Other changes:
- removed handshake3.
-	testutil vastly simplified peer
-	secio bugfix + debugging logs
-	testutil: RandKeyPair
-	backpressure bugfix: w.o.w.
-	peer: added hex enc/dec
-	peer: added a PeerInfo struct
  PeerInfo is a small struct used to pass around a peer with
 	a set of addresses and keys. This is not meant to be a
 	complete view of the system, but rather to model updates to
 	the peerstore. It is used by things like the routing system.
-	updated peer/queue + peerset
-	latency metrics
-	testutil: use crand for PeerID gen
 	RandPeerID generates random "valid" peer IDs. it does not
 	NEED to generate keys because it is as if we lost the key
 	right away. fine to read some randomness and hash it. to
 	generate proper keys and an ID, use:
 	  sk, pk, _ := testutil.RandKeyPair()
 	  id, _ := peer.IDFromPublicKey(pk)
 	Also added RandPeerIDFatal helper
- removed old spipe
- updated seccat
- core: cleanup initIdentity
- removed old getFromPeerList

for safety!

use mockpeer.WithID methods to create peers in tests

Putting the block generator in a util dir until blocks.

Can't put it in util/testutil because the util/testutil/dag-generator
imports blockservice and blockservice uses the generator.

Tough problem. This'll do for now.

@whyrusleeping i hope this makes it a bit easier to work with tests

@whyrusleeping This appears to be a timing issue. The asynchronous
nature of the new structure provides has the bitswap waiting on the
context a bit more. This isn't a problem at all, but in this test, it
makes the functions return in an inconveniently timely manner.

TODO don't let the test depend on time.

fixes data race detected in a testnet test

![](http://m.memegen.com/77n7dk.jpg)

We'll want a `type blocks.Block interface {}` later, but
for now, make sure Blockstore uses ptrs for both Get and Put.

+ fix NewBlock output compile error

true -> always send to peer

false -> use ledger-based strategy described in IPFS paper draft 3
