Detailed Description

The telnet DAEMON.

After start the net you can start this daemon. It uses the previously inited pseudo-terminales (pty.c) getting a new terminal with getpty(). This function gives a terminal name passing a opened socket like parameter.

With register_telnetd() you add a new command in the shell to start this daemon interactively. (Login in /dev/console of course)

Sorry but OOB is not still implemented. (This is the first version)
