fix: simplify transport interface, update interfaces for use with lib…
…p2p (#180) * Ensure implementation of interfaces (e.g. `@libp2p/connection` implements `Connection` now) * Adds mocks for missing components (connection encrypter, etc) * Introduce `Components` class to hold system components that modules require access too - this means system components do not need to depend on `libp2p` any more * Add `Initializable` interface to allow injecting `Components` instance at runtime * Make naming of interfaces less cryptic - e.g. `Muxer` becomes `StreamMuxer`, etc * Introduces peer collections - lists, maps and sets keyed by `PeerId` instead of strings * Adds `.trace` field to `@libp2p/logger` for detailed logging * Pubsub implementations are now expected to serialize their own RPC representations * PeerIds now only stringify to `base58btc`, since a stringified PeerId is a multihash digest encoded in base58btc
