swarm/: Enable advanced dialing requests (#2317)
Enable advanced dialing requests both on `Swarm` and via
`NetworkBehaviourAction`. Users can now trigger a dial with a specific
set of addresses, optionally extended via
`NetworkBehaviour::addresses_of_peer`. In addition the whole process is
now modelled in a type safe way via the builder pattern.

Example of a `NetworkBehaviour` requesting a dial to a specific peer
with a set of addresses additionally extended through
`NetworkBehaviour::addresses_of_peer`:

```rust
NetworkBehaviourAction::Dial {
    opts: DialOpts::peer_id(peer_id)
              .condition(PeerCondition::Always)
              .addresses(addresses)
              .extend_addresses_through_behaviour()
              .build(),
    handler,
}
```

Example of a user requesting a dial to an unknown peer with a single
address via `Swarm`:

```rust
swarm1.dial(
    DialOpts::unknown_peer_id()
        .address(addr2.clone())
        .build()
)
```

protocols/ping: Don't force close conn if not supported by remote (#2149)
Don't close connection if ping protocol is unsupported by remote. Previously, a
failed protocol negotation for ping caused a force close of the connection. As a
result, all nodes in a network had to support ping. To allow networks where some
nodes don't support ping, we now emit `PingFailure::Unsupported` once for every
connection on which ping is not supported.

swarm/: Drive ExpandedSwarm via Stream trait only (#2100)
Change `Stream` implementation of `ExpandedSwarm` to return all
`SwarmEvents` instead of only the `NetworkBehaviour`'s events.

Remove `ExpandedSwarm::next_event`. Users can use `<ExpandedSwarm as
StreamExt>::next` instead.

Remove `ExpandedSwarm::next`. Users can use `<ExpandedSwarm as
StreamExt>::filter_map` instead.

swarm/src/lib: Remove Deref and DerefMut impls on Swarm (#1995)
Remove `Deref` and `DerefMut` implementations previously dereferencing
to the `NetworkBehaviour` on `Swarm`. Instead one can access the
`NetworkBehaviour` via `Swarm::behaviour` and `Swarm::behaviour_mut`.
Methods on `Swarm` can now be accessed directly, e.g. via
`my_swarm.local_peer_id()`.

Reasoning: Accessing the `NetworkBehaviour` of a `Swarm` through `Deref`
and `DerefMut` instead of a method call is an unnecessary complication,
especially for newcomers. In addition, `Swarm` is not a smart-pointer
and should thus not make use of `Deref` and `DerefMut`, see documentation
from the standard library below.

> Deref should only be implemented for smart pointers to avoid
confusion.

[identify] Implement /ipfs/id/push/1.0.0 alongside some refactoring. (#1999)
* Implement /ipfs/id/push/1.0.0 alongside some refactoring.

  * Implement /ipfs/id/push/1.0.0, i.e. the ability to actively
    push information of the local peer to specific remotes.
  * Make the initial delay as well as the recurring delay
    for the periodic identification requests configurable,
    introducing `IdentifyConfig`.

* Fix test.

* Fix example.

protocols/gossipsub: Add Gossipsub v1.1 support
This commit upgrades the current gossipsub implementation to support the [v1.1
spec](https://github.com/libp2p/specs/blob/master/pubsub/gossipsub/gossipsub-v1.1.md).

It adds a number of features, bug fixes and performance improvements. 

Besides support for all new 1.1 features, other improvements that are of particular note: 

- Improved duplicate LRU-time cache (this was previously a severe bottleneck for
  large message throughput topics)
- Extended message validation configuration options
- Arbitrary topics (users can now implement their own hashing schemes)
- Improved message validation handling - Invalid messages are no longer dropped
  but sent to the behaviour for application-level processing (including scoring)
- Support for floodsub, gossipsub v1 and gossipsub v2
- Protobuf encoding has been shifted into the behaviour. This has permitted two
  improvements:
     1. Message size verification during publishing (report to the user if the
        message is too large before attempting to send).
     2. Message fragmentation. If an RPC is too large it is fragmented into its
        sub components and sent in smaller chunks.

Additional Notes

The peer eXchange protocol defined in the v1.1 spec is inactive in its current
form. The current implementation permits sending `PeerId` in `PRUNE` messages,
however a `PeerId` is not sufficient to form a new connection to a peer. A
`Signed Address Record` is required to safely transmit peer identity
information. Once these are confirmed (https://github.com/libp2p/specs/pull/217)
a future PR will implement these and make PX usable.

[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.

protocols/gossipsub: Add message signing and verification configuration (#1583)
This adds optional message signing and verification to the gossipsub protocol as
per the libp2p specifications.

In addition this commit:

- Removes the LruCache received cache and simply uses the memcache in it's
  place.

- Send subscriptions to all peers

- Prevent invalid messages from being gossiped

- Send grafts when subscriptions are added to the mesh
