crypto/tls: support TLS_FALLBACK_SCSV as a server. A new attack on CBC padding in SSLv3 was released yesterday[1]. Go only supports SSLv3 as a server, not as a client. An easy fix is to change the default minimum version to TLS 1.0 but that seems a little much this late in the 1.4 process as it may break some things. Thus this patch adds server support for TLS_FALLBACK_SCSV[2] -- a mechanism for solving the fallback problem overall. Chrome has implemented this since February and Google has urged others to do so in light of yesterday's news. With this change, clients can indicate that they are doing a fallback connection and Go servers will be able to correctly reject them.
