Currently an ECDHE handshake uses the client's curve preference. This generally means that we use P-521. However, P-521's strength is mismatched with the rest of the cipher suite in most cases and we have a fast, constant-time implementation of P-256. With this change, Go servers will use P-256 where the client supports it although that can be overridden in the Config. LGTM=bradfitz R=bradfitz CC=golang-codereviews https://golang.org/cl/66060043
