* 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).
