crypto/tls: buffer handshake messages.

2016-06-01T23:26:04Z

This change causes TLS handshake messages to be buffered and written in a single Write to the underlying net.Conn. There are two reasons to want to do this: Firstly, it's slightly preferable to do this in order to save sending several, small packets over the network where a single one will do. Secondly, since 37c28759ca46cf381a466e32168a793165d9c9e9 errors from Write have been returned from a handshake. This means that, if a peer closes the connection during a handshake, a “broken pipe” error may result from tls.Conn.Handshake(). This can mask any, more detailed, fatal alerts that the peer may have sent because a read will never happen. Buffering handshake messages means that the peer will not receive, and possibly reject, any of a flow while it's still being written.
