[reviewpad]

AI-Generated Summary: This pull request introduces several changes to the networking code, including enabling/disabling mDNS and AutoNAT based on a new local flag, adding support for specifying an external address, and updating dependencies. Additionally, it removes manual addition of addresses to the Kademlia behavior, opting to use the identify behavior to receive listening addresses from peers instead. The address handling is refactored, adding the multiaddr_is_global and multiaddr_strip_p2p helper methods. AutoNAT events are also now being logged. Overall, these changes improve the networking capabilities and configuration options of the code.

It adds libp2p-autonat, libp2p-mplex, libp2p-noise, libp2p-tcp, and libp2p-yamux to the Cargo.lock and safenode/Cargo.toml. The code has been modified to enable mDNS peer discovery when running on a local network, provide an option for specifying an external address, and other related changes for handling AutoNAT events, identifying info received from peers, and filtering ip addresses. Additionally, it updates the test cases to reflect these changes.

AI-Generated Summary: This pull request adds new dependencies (libp2p-autonat, libp2p-mplex, libp2p-noise, libp2p-yamux, nohash-hasher) to Cargo.lock and introduces new options for running the node on a local network and specifying an external address. In SwarmDriver, the AutoNAT status change is logged, the provided external address is added if available, and mDNS is enabled only if in local mode. A couple of utility functions for multiaddress handling like multiaddr_strip_p2p and multiaddr_is_global have been added.
