In the libp2p specs, the only handshake pattern that is specified is the XX handshake. Support for other handshake patterns can be added through external modules. While we are at it, we rename the remaining types to following the laid out naming convention.
The tests for handshakes other than XX are removed. The handshakes still work as we don't touch them in this patch.

The `unreachable_pub` lint makes us aware of uses of `pub` that are not actually reachable from the crate root. This is considered good because it means reading a `pub` somewhere means it is actually public API. Some of our crates are quite large and keeping their entire API surface in your head is difficult.
We should strive for most items being `pub(crate)`. This lint helps us enforce that.

With https://github.com/libp2p/rust-libp2p/pull/3658, these crates depend on the `0.42.1` release to access the new `ToSwarm` type. With the currently specified version, a user could theoretically run into a compile error if they pin `libp2p-swarm` to `0.42.0` in their lockfile but update to the latest patch release of one of these crates.

Allows folks like @bajtos to use the crate, see https://github.com/filecoin-station/zinnia/pull/85.
I opted for not exposing the crate through the `libp2p` meta crate as it is a testing tool only. @thomas
let me know if you prefer me to do so.

Implementation of the libp2p perf protocol according to https://github.com/libp2p/specs/pull/478/.
//CC @MarcoPolo as the author of the specification.
**Don't (yet) expect this to produce reliable performance metrics.**
