Updates: * cid, multihash, and multiaddr to ensure that minimal varints are used. * log to deduplicate some code between version 2 and version 1. * multistream to avoid writing from multiple threads. * badger/datastore to harden prefix handling in queries. * libp2p to 0.5.2 BREAKING: The new libp2p version now formats addresses with /p2p instead of /ipfs. /ipfs multiaddrs are still supported.
