Revert "This commit adds nsh_consolechild(). I noticed that there are several examples that call nsh_consolemain.c to create to create a new NSH session. That will not always work because nsh_consolemain() performs the one-time initialization needed by the NSH library: Mounting, reading, and running the start-up script, configuring USB tracing. Some of those actions will cause failures if attempted twice."

* tracing options. It should be spawned only once for this reason.
*
* This function handles generic /dev/console character devices, or

* Description:
* This interfaces maybe to called or started with task_start to start a

*
* This function equivalent to nsh_consolemain(), except it assumes that

* simply startes a NSH session with no re-initialization.
*
* Like nsh_consolmain(), this functions 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).
