Remove the last remains of slave mode

Almost nothing was left of it.

The only thing this commit actually removes is support for reading
input commands from stdin. But you can emulate this via:

 --input-file=/dev/stdin --input-terminal=no

However, this won't work on Windows. Just use a named pipe.
