kris/th5: Alternative TLS implementation in Go - th5

Alternative TLS implementation in Go

Anmol Sethi c7f1c5bf4e crypto/tls: document ConnectionState.NegotiatedProtocol more clearly ConnectionState.NegotiatedProtocol's documentation implies that it will always be from Config.NextProtos. This commit clarifies that there is no guarantee. This commit also adds a note to ConnectionState.NegotiatedProtocolIsMutual, making it clear that it is client side only.
