[lib] Do not call vty_close in vty_log_out to avoid possible free memory access

2006-07-10 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* vty.c: (vty_log_out) Do not call vty_close, because this could
	  result in a parent function's accessing the freed memory.
	  Instead, set status VTY_CLOSE and call shutdown(vty->fd, SHUT_RDWR).
	  And add a comment on vty_close.
