f293594144 Several changes.
- Pin `futures_codec` to version 0.3.3 as later versions require
at least bytes-0.5 which he have not upgraded to yet.
- Replace `futures::executor::block_on` with `async_std::task::block_on`
where `async-std` is already a dependency to work around an issue with
`park`/`unpark` behaviour.
- Use the published version of `quicksink`.

Rework the transport upgrade API. (#1240)
* Rework the transport upgrade API.

ALthough transport upgrades must follow a specific pattern
in order fot the resulting transport to be usable with a
`Network` or `Swarm`, that pattern is currently not well
reflected in the transport upgrade API. Rather, transport
upgrades are rather laborious and involve non-trivial code
duplication.

This commit introduces a `transport::upgrade::Builder` that is
obtained from `Transport::upgrade`. The `Builder` encodes the
previously implicit rules for transport upgrades:

  1. Authentication upgrades must happen first.
  2. Any number of upgrades may follow.
  3. A multiplexer upgrade must happen last.

Since multiplexing is the last (regular) transport upgrade (because
that upgrade yields a `StreamMuxer` which is no longer a `AsyncRead`
/ `AsyncWrite` resource, which the upgrade process is based on),
the upgrade starts with `Transport::upgrade` and ends with
`Builder::multiplex`, which drops back down to the `Transport`,
providing a fluent API.

Authentication and multiplexer upgrades must furthermore adhere
to a minimal contract w.r.t their outputs:

  1. An authentication upgrade is given an (async) I/O resource `C`
     and must produce a pair `(I, D)` where `I: ConnectionInfo` and
     `D` is a new (async) I/O resource `D`.
  2. A multiplexer upgrade is given an (async) I/O resource `C`
     and must produce a `M: StreamMuxer`.

To that end, two changes to the `secio` and `noise` protocols have been
made:

  1. The `secio` upgrade now outputs a pair of `(PeerId, SecioOutput)`.
     The former implements `ConnectionInfo` and the latter `AsyncRead` /
     `AsyncWrite`, fulfilling the `Builder` contract.

  2. A new `NoiseAuthenticated` upgrade has been added that wraps around
     any noise upgrade (i.e. `NoiseConfig`) and has an output of
     `(PeerId, NoiseOutput)`, i.e. it checks if the `RemoteIdentity` from
     the handshake output is an `IdentityKey`, failing if that is not the
     case. This is the standard upgrade procedure one wants for integrating
     noise with libp2p-core/swarm.

* Cleanup

* Add a new integration test.

* Add missing license.

9793c42859 Replace listen_addr with local_addr. (#1223)
* Replace `listen_addr` with `local_addr`.

In `ListenerUpgrade`, `ConnectedPoint` and other event types where we
were previously using the listen address we now report the local address
of an incoming connection. The reason being that it is difficult to get
the listen address right. In case clients want to know, which listener
produced an incoming connection upgrade they are advised to use the
`ListenerId` for such purposes.

* Update transports/tcp/src/lib.rs

[multistream-select] Reduce roundtrips in protocol negotiation. (#1212)
* Remove tokio-codec dependency from multistream-select.

In preparation for the eventual switch from tokio to std futures.

Includes some initial refactoring in preparation for further work
in the context of https://github.com/libp2p/rust-libp2p/issues/659.

* Reduce default buffer sizes.

* Allow more than one frame to be buffered for sending.

* Doc tweaks.

* Remove superfluous (duplicated) Message types.

* Reduce roundtrips in multistream-select negotiation.

1. Enable 0-RTT: If the dialer only supports a single protocol, it can send
   protocol data (e.g. the actual application request) together with
   the multistream-select header and protocol proposal. Similarly,
   if the listener supports a proposed protocol, it can send protocol
   data (e.g. the actual application response) together with the
   multistream-select header and protocol confirmation.

2. In general, the dialer "settles on" an expected protocol as soon
   as it runs out of alternatives. Furthermore, both dialer and listener
   do not immediately flush the final protocol confirmation, allowing it
   to be sent together with application protocol data. Attempts to read
   from the negotiated I/O stream implicitly flushes any pending data.

3. A clean / graceful shutdown of an I/O stream always completes protocol
   negotiation.

The publich API of multistream-select changed slightly, requiring both
AsyncRead and AsyncWrite bounds for async reading and writing due to
the implicit buffering and "lazy" negotiation. The error types have
also been changed, but they were not previously fully exported.

Includes some general refactoring with simplifications and some more tests,
e.g. there was an edge case relating to a possible ambiguity when parsing
multistream-select protocol messages.

* Further missing commentary.

* Remove unused test dependency.

* Adjust commentary.

* Cleanup NegotiatedComplete::poll()

* Fix deflate protocol tests.

* Stabilise network_simult test.

The test implicitly relied on "slow" connection establishment
in order to have a sufficient probability of passing.
With the removal of roundtrips in multistream-select, it is now
more likely that within the up to 50ms duration between swarm1
and swarm2 dialing, the connection is already established, causing
the expectation of step == 1 to fail when receiving a Connected event,
since the step may then still be 0.

This commit aims to avoid these spurious errors by detecting runs
during which a connection is established "too quickly", repeating
the test run.

It still seems theoretically possible that, if connections are always
established "too quickly", the test runs forever. However, given that
the delta between swarm1 and swarm2 dialing is 0-50ms and that the
TCP transport is used, that seems probabilistically unlikely.
Nevertheless, the purpose of the artificial dialing delay between
swarm1 and swarm2 should be re-evaluated and possibly at least
the maximum delay further reduced.

* Complete negotiation between upgrades in libp2p-core.

While multistream-select, as a standalone library and providing
an API at the granularity of a single negotiation, supports
lazy negotiation (and in particular 0-RTT negotiation), in the
context of libp2p-core where any number of negotiations are
composed generically within the concept of composable "upgrades",
it is necessary to wait for protocol negotiation between upgrades
to complete.

* Clarify docs. Simplify listener upgrades.

Since reading from a Negotiated I/O stream implicitly flushes any pending
negotiation data, there is no pitfall involved in not waiting for completion.

Fix connection & handler shutdown when using KeepAlive::Now. (#1072)
* Fix connection & handler shutdown when using `KeepAlive::Now`.

Delay::new(Instant::now()) is never immediately ready, resulting in
`KeepAlive::Now` to have no effect, since the delay is re-created on
every execution of `poll()` in the `NodeHandlerWrapper`. It can also
send the node handler into a busy-loop, since every newly
created Delay will trigger a task wakeup, which creates a new Delay
with Instant::now(), and so forth.

The use of `Delay::new(Instant::now())` for "immediate" connection shutdown
is therefore removed here entirely. An important assumption is thereby
that as long as the node handler non-empty `negotiating_in` and `negotiating_out`,
the handler is not dependent on such a Delay for task wakeup.

* Trigger CI.

libp2p-ping improvements. (#1049)
* libp2p-ping improvements.

  * re #950: Removes use of the `OneShotHandler`, but still sending each
    ping over a new substream, as seems to be intentional since #828.

  * re #842: Adds an integration test that exercises the ping behaviour through
    a Swarm, requiring the RTT to be below a threshold. This requires disabling
    Nagle's algorithm as it can interact badly with delayed ACKs (and has been
    observed to do so in the context of the new ping example and integration test).

  * re #864: Control of the inbound and outbound (sub)stream protocol upgrade
    timeouts has been moved from the `NodeHandlerWrapperBuilder` to the
    `ProtocolsHandler`. That may also alleviate the need for a custom timeout
    on an `OutboundSubstreamRequest` as a `ProtocolsHandler` is now free to
    adjust these timeouts over time.

Other changes:

  * A new ping example.
  * Documentation improvements.

* More documentation improvements.

* Add PingPolicy and ensure no event is dropped.

* Remove inbound_timeout/outbound_timeout.

As per review comment, the inbound timeout is now configured
as part of the `listen_protocol` and the outbound timeout as
part of the `OutboundSubstreamRequest`.

* Simplify and generalise.

Generalise `ListenProtocol` to `SubstreamProtocol`, reusing it in
the context of `ProtocolsHandlerEvent::OutboundSubstreamRequest`.

* Doc comments for SubstreamProtocol.

* Adapt to changes in master.

* Relax upper bound for ping integration test rtt.

Consolidate keypairs in core. (#972)
* Consolidate keypairs in core.

Introduce the concept of a node's identity keypair in libp2p-core,
instead of only the public key:

  * New module: libp2p_core::identity with submodules for the currently
    supported key types. An identity::Keypair and identity::PublicKey
    support the creation and verification of signatures. The public key
    supports encoding/decoding according to the libp2p specs.

  * The secio protocol is simplified as a result of moving code to libp2p-core.

  * The noise protocol is slightly simplified by consolidating ed25519
    keypairs in libp2p-core and using x25519-dalek for DH. Furthermore,
    Ed25519 to X25519 keypair conversion is now complete and tested.

Generalise over the DH keys in the noise protocol.

Generalise over the DH keys and thus DH parameter in handshake patterns
of the Noise protocol, such that it is easy to support other DH schemes
in the future, e.g. X448.

* Address new review comments.
