Filippo Valsorda 30cc978085 crypto/tls: enable TLS 1.3 and update tests To disable TLS 1.3, simply remove VersionTLS13 from supportedVersions, as tested by TestEscapeRoute, and amend documentation. To make it opt-in, revert the change to (*Config).supportedVersions from this CL. I did not have the heart to implement the early data skipping feature when I realized that it did not offer a choice between two abstraction-breaking options, but demanded them both (look for handshake type in case of HelloRetryRequest, trial decryption otherwise). It's a lot of complexity for an apparently small gain, but if anyone has strong opinions about it let me know. Note that in TLS 1.3 alerts are encrypted, so the close_notify peeking to return (n > 0, io.EOF) from Read doesn't work. If we are lucky, those servers that unexpectedly close connections after serving a single request will have stopped (maybe thanks to H/2) before they got updated to TLS 1.3. Relatedly, session tickets are now provisioned on the client first Read instead of at Handshake time, because they are, well, post-handshake messages. If this proves to be a problem we might try to peek at them. Doubled the tests that cover logic that's different in TLS 1.3. The benchmarks for TLS 1.2 compared to `be0f3c286b` (before TLS 1.3 and its refactors, after CL 142817 changed them to use real connections) show little movement. name old time/op new time/op delta
