Release v0.0.23

Breaking Changes:

• github.com/libp2p/go-libp2p/p2p/protocol/ping.Ping now returns a channel of results (PingResult{Error, RTT}) instead of a stream of RTTs and a single error. That way, we can return errors we encounter after we start pinging instead of simply closing the channel.

Features:

• Libp2p now (optionally) supports using OpenSSL for all RSA operations for a significant performance boost. To enable, build with -tags=openssl.

Bug Fixes:

• The identify service is now correctly canceled when the host shuts down.

Dependency Updates:

• Goprocess updated to reduce the number of goroutines it uses.
• Update go-libp2p-circuit updated to improve performance under heavy load.
