Also more refactoring of bitswap in general, including some perf
improvements and eventlog removal.

clean up, and buffer channels

move some things around

correctly buffer work messages

more cleanup, and improve test perf

remove unneccessary test

revert changes to bitswap message, they werent necessary

- Modified Godeps/Godeps.json by hand
- [TEST] Updated welcome docs hash to sharness
- [TEST] Updated contact doc
- [TEST] disabled breaking test (t0080-repo refs local)

- updated go-ctxgroup and goprocess
ctxgroup: AddChildGroup was changed to AddChild. Used in two files:
- p2p/net/mock/mock_net.go
- routing/dht/dht.go

- updated context from hg repo to git
prev. commit in hg was ad01a6fcc8a19d3a4478c836895ffe883bd2ceab. (context: make parentCancelCtx iterative)
represents commit 84f8955a887232b6308d79c68b8db44f64df455c in git repo

- updated context to master (b6fdb7d8a4ccefede406f8fe0f017fb58265054c)

Aaron Jacobs (2):
net/context: Don't accept a context in the DoSomethingSlow example.

Let's save log.Error for things the user can take action on.
Moved all our diagnostics to log.Debug. We can ideally reduce them
even further.

This addr manager should seriously help with the addrsplosion
problem.

Network now signals when it successfully listens on some address
or when an address shuts down. This will be used to establish and
close nat port mappings. It could also be used to notify peers
of address changes.

With these notifications, bitswap can reclaim all resources
for any outstanding work for a peer.

cc @briantigerchow @whyrusleeping

mitigated adding our own addresses where received
from peers

see #573

Bitswap doesn't usually care about dialing. the underlying
network adapter can make sure of that.

@jbenet @whyrusleeping

This bug (missing return) could tie up the client worker and cause
operations to come to a halt.

The net package is the next to move. It will be massaged
a bit still to fix the Network / "NetworkBackend" conflict.

I think it's time to move a lot of the peer-to-peer networking
but-not-ipfs-specific things into its own package: p2p.
This could in the future be split off into its own library.
The first thing to go is the peer.

@jbenet @whyrusleeping

This commit replaces peer.PeerInfo with peer.ID in the bitswap package

@jbenet @whyrusleeping

the next commit will change bitswap.Network.FindProviders to only deal
with IDs

This reverts commit bf88f1aec5e3d397f97d64de52b52686cc7a8c8f.

Had to change the network interface from DialPeer(peer.ID) to
DialPeer(peer.PeerInfo), so that addresses of a provider are
handed to the network.

@maybebtc and I are discussing whether this should go all the
way down to the network, or whether the network _should always
work_ with just an ID (which means the network needs to be
able to resolve ID -> Addresses, using the routing system.
This latter point might mean that "routing" might need to
break down into subcomponents. It's a bit sketchy that
the Network would become smarter than just dial/listen and
I/O, but maybe there's a distinction between net.Network,
and something like a peernet.Network that has routing
built in...)

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

remove 'adapter' concept
instead, describe the component as the bitswap network

it's still an adapter, but it's just not necessary to describe it as
such
