 * Name: nsh_consolemain (Normal character device version)
 *
 * Description:
 *   This interfaces may be to called or started with task_start to start a
 *   single an NSH instance that operates on stdin and stdout.  This
 *   function does not normally return (see below).
 *
 *   This version of nsh_consolmain handles generic /dev/console character
 *   devices (see nsh_usbconsole.c and usb_usbkeyboard for other versions
 *   for special USB console devices).
 *
 * Input Parameters:
 *   Standard task start-up arguments.  These are not used.  argc may be
 *   zero and argv may be NULL.
 *
 * Returned Values:
 *   This function does not normally return.  exit() is usually called to
 *   terminate the NSH session.  This function will return in the event of
 *   an error.  In that case, a non-zero value is returned (EXIT_FAILURE=1).
