* monitor/mon-prmisc.c: Correct print line.
	* shell/Makefile.am: Added new file telnetd.c.
	* shell/telnetd.c, shell/telnetd.h, shell/pty.c: New files.
	* shell/shell.c, shell/cmds.c, shell/shell.h: Numerous improvments:
	   - The shell_init has a new parameter 'forever' because in
	     /dev/console you need that this process runs forever but in
	     tcp/ip not. (respawn?)
	   - A new task for every session opened trought tcp/ip telnet client.
	     (the chargen,daytime and more are possible of implementation but
	     I ask me if they are necesary)
	   - Exit from the session delete the task and when the client fails too.
	   - More cmds have been implemented. (very reduced version of these)
	     umask, chmod, id, whoami, rm, cat, ...
	   - A reduced line edit has been implemented.
	       Ctrl-C abort the input,
	       Ctrl-d in the first position gives EOF (logout).
	       '\b' and DEL makes the rubout operation.
	       I think that readline() for every session spents a lot of resources.

This directory contains a shell user extension
primary features:

   + create a user shell terminal task.

This code has not been extensively tested.  It is provided as a tool
for RTEMS users to open more shell terminal.
Suggestions and comments are appreciated.

NOTES:

1.  printf() & getchar() works but you can't use 
    0,1,2 like fildes. You need to use fileno(stdin),fileno(stdout),...
    
2.  You only need a termios dev to start a new session, add your new commands
    and enjoy it.

3.  If you have tcp/ip inited you can start telnetd daemon.
    You need register pseudo-terminals driver into device drivers table.
    16 ptyX termios device terminales are created into /dev/.
    Calling rtems_initialize_telnetd() starts the daemon.
    Enjoy it.

FUTURE:

1.  Adding new commands in cmds.c to give file manegement to shell.
