fixes #939

This patch updates go-libp2p for the stream interface changes in go-libp2p-core
0.7.0. This is a _significant_ breaking change to streams and all users should
read https://github.com/libp2p/go-libp2p-core/releases/tag/v0.7.0. In practice,
this change should remove a significant footgun.

TL;DR:

* `Stream.Close` now behaves like `net.TCPConn.Close`.
* There is a new `Stream.CloseWrite` (send an EOF) and `Stream.CloseRead` (close
  for reading), behaving like their counterparts in `net.TCPConn`.

* Export StreamComplement/ConnComplement convenience functions.
* Make the TestNotifications test pass reliably, even when we have a bunch of
streams (identify, etc.).
* Make the mock net order disconnect events after connect events.
* Make closing one side of a connection actually close both sides.
* Make it possible to extract a mock stream's complement.
* Fire remote events at the same time as the local events.

No need to manually subtract timestamps.

- changed GetStreams function from mock_conn.go to call allStreams which has the same functionality but is concurrent safe
- changed protocol field from mock_stream to be concurrent safe. Taken the implementation from swarm_stream.go

This was causing https://github.com/ipfs/go-ipfs/pull/5637#issuecomment-432792969

Before, on close, we:

1. Weren't completing the write.
2. Flushing the buffer without waiting the latency delay.

This fixes that by using two separate channels for close/reset and ignoring the
close channel in deliverOrWait.

* Fix the tests to work with separate reset/close methods.
* Ensure we interrupt writes on reset.
* Always delay the proper time even if we're sending short messages.
* Copy buffers as we send them. `Write` is not allowed to hang onto buffers. If
  we run into performance issues, we can always add a buffer pool.

- 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)

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