[mplex, yamux] Streamline configuration API. (#1822)
* Streamline mplex and yamux configurations.

  * For all configuration options that exist for both multiplexers
    and have the same semantics, use the same names for the
    configuration.
  * Rename `Config` to `YamuxConfig` for consistentcy with
    the majority of other protocols, e.g. `MplexConfig`, `PingConfig`,
    `KademliaConfig`, etc.
  * Completely hide `yamux` APIs within `libp2p-yamux`. This allows
    to fully control the libp2p API and streamline it with other
    muxer APIs, consciously choosing e.g. which configuration options
    to make configurable in libp2p and which to fix to certain values.
    It does also not necessarily prescribe new incompatible version bumps of
    yamux for `libp2p-yamux`, as no `yamux` types are exposed. The cost
    is some more duplication of configuration options in the API, as well
    as the need to update `libp2p-yamux` if `yamux` introduces new
    configuration options that `libp2p-yamux` wants to expose as well.

* Update CHANGELOGs.

[multistream-select] Fix panic with V1Lazy (regression) and more convenient transport boxing. (#1783)
* [multistream-select] Fix panic with V1Lazy and add integration tests.

Fixes a panic when using the `V1Lazy` negotiation protocol,
a regression introduced in https://github.com/libp2p/rust-libp2p/pull/1484.

Thereby adds integration tests for a transport upgrade with both
`V1` and `V1Lazy` to the `multistream-select` crate to prevent
future regressions.

* Cleanup.

* Update changelog.

[ping] Add missing flush after write. (#1770)
After sending the ping and before awaiting the pong,
the stream must be flushed to guarantee the data is
sent before awaiting the reply.

[ping] Refactor the ping protocol for conformity. (#1692)
* Refactor the ping protocol.

Such that pings are sent over a single substream, as it is
done in other libp2p implementations. Note that, since each
peer sends its pings over a single, dedicated substream,
every peer that participates in the protocol has effectively
two open substreams.

* Cleanup

* Update ping changelog.

* Update protocols/ping/src/protocol.rs

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`.

Merge master into stable-futures (#1271)
* Configurable multistream-select protocol. Add V1Lazy variant. (#1245)

Make the multistream-select protocol (version) configurable
on transport upgrades as well as for individual substreams.

Add a "lazy" variant of multistream-select 1.0 that delays
sending of negotiation protocol frames as much as possible
but is only safe to use under additional assumptions that
go beyond what is required by the multistream-select v1
specification.

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.

Add back simple, optional keep-alive to libp2p-ping. (#1088)
This is now a very simple option serving multiple purposes:

  * It allows for stable (integration) tests involving a Swarm, which
    are otherwise subject to race conditions due to the connection being
    allowed to terminate at any time with `KeepAlive::No`
    (which remains the default).

  * It makes for a more entertaining ping example which continuously
    sends pings.

  * Maybe someone wants to use the ping protocol for application-layer
    connection keep-alive after all.

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.
