Previously, a protocol could be any sequence of bytes as long as it started with `/`. Now, we directly parse a protocol as `String` which enforces it to be valid UTF8.
To notify users of this change, we delete the `ProtocolName` trait. The new requirement is that users need to provide a type that implements `AsRef<str>`.
We also add a `StreamProtocol` newtype in `libp2p-swarm` which provides an easy way for users to ensure their protocol strings are compliant. The newtype enforces that protocol strings start with `/`. `StreamProtocol` also implements `AsRef<str>`, meaning users can directly use it in their upgrades.
`multistream-select` by itself only changes marginally with this patch. The only thing we enforce in the type-system is that protocols must implement `AsRef<str>`.

Instead of relying on `protoc` and buildscripts, we generate the bindings using `pb-rs` and version them within our codebase. This makes for a better IDE integration, a faster build and an easier use of `rust-libp2p` because we don't force the `protoc` dependency onto them.
Resolves#3024.
Pull-Request: #3312.
With this commit `libp2p-autonat` no longer discards the whole remote payload in case an addr is unparsable, but instead logs the failure and skips the unparsable multiaddr.
See libp2p#3244 for details.
This commit adds a behaviour protocol that implements the AutoNAT specification.
It enables users to detect whether they are behind a NAT. The Autonat Protocol
implements a Codec for the Request-Response protocol, and wraps it in a new
Network Behaviour with some additional functionality.
