Send all three of stdin, stdout, stderr from the client to the server, so that

commands can directly make use of them. This means that load-buffer and
save-buffer can have "-" as the file to read from stdin or write to stdout.

This is a protocol version bump so the tmux server will need to be restarted
after upgrade (or an older client used).
