As a listening client, when requesting a reservation with a relay, the relay
responds with its public addresses. The listening client can then use the public
addresses of the relay to advertise itself as reachable under a relayed
address (`/<public-relay-addr>/p2p-circuit/p2p/<listening-client-peer-id>`).
The above operates under the assumption that the relay knows its public address.
A relay learns its public address from remote peers, via the identify protocol.
In the case where the relay just started up, the listening client might be the
very first node to connect to it.
Such scenario allows for a race condition. The listening client requests a
reservation from the relay, while the relay requests its public address from the
listening client. The former needs to contain the response from the latter.
This commit serializes the two requests, making sure, in the case of a freshly
started relay, that the listening client tells the relay its public address
before requesting a reservation from the relay.

Previously `libp2p-swarm` required a `Transport` to be `Clone`. Methods
on `Transport`, e.g. `Transport::dial` would take ownership, requiring
e.g. a `Clone::clone` before calling `Transport::dial`.
The requirement of `Transport` to be `Clone` is no longer needed in
`libp2p-swarm`. E.g. concurrent dialing can be done without a clone per
dial.
This commit removes the requirement of `Clone` for `Transport` in
`libp2p-swarm`. As a follow-up methods on `Transport` no longer take
ownership, but instead a mutable reference (`&mut self`).
On the one hand this simplifies `libp2p-swarm`, on the other it
simplifies implementations of `Transport`.

* *: Import `libp2p` with `default-features = false`
While not a win in most cases, it reduces compile time for tests of
individual crates.
* Cargo.toml: Set features for examples
A `ProtocolsHandler`, now `ConnectionHandler`, handels a connection, not
a protocol. Thus the name `CONNECTIONHandler` is more appropriate.
Next to the rename of `ProtocolsHandler` this commit renames the `mod
protocols_handler` to `mod handler`. Finally all combinators (e.g.
`ProtocolsHandlerSelect`) are renamed appropriately.
