Jiuzhu Dong 9f79bf183a nsh/script: support rc.sysinit script
Follow: http://glennastory.net/boot/sysinit.html

This is first script that init runs is rc.sysinit. This
script does serval initialization tasks about basic service.

The boot sequence currently provided to the board level is:
board_earlyinitialize->
    board_lateinitialize(Peripherals driver, core driver, ...)->
	run rcS script(mount fs, run service) ->
	    board_appinitialize->

After this patch:
The boot sequence currently provided to the board level is:
board_earlyinitialize->
    board_lateinitialize(core driver,...)->
	run rc.sysinit script(mount fs, run core service) ->
	    board_appinitialize(Peripherals driver)->
		run rcS script(run other service)->

So, Peripheral drivers can do more with the file system and
core services.

* Name: nsh_consolemain (Normal character device version)
*
* Description:
* This interface 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_consolemain 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).
