* Name: nsh_initialize

* Description:
* This interface is used to initialize the NuttShell (NSH).
* nsh_initialize() should be called one during application start-up prior
* to executing either nsh_consolemain() or nsh_telnetstart().
*
* Input Parameters:
* None

* Name: nsh_consolemain
*
* Description:
* This interfaces maybe to called or started with task_start to start a
* single an NSH instance that operates on stdin and stdout. This
* function does not return.
*
* This function handles generic /dev/console character devices, or
* special USB console devices. The USB console requires some special
* operations to handle the cases where the session is lost when the
* USB device is unplugged and restarted when the USB device is plugged
* in again.
*
* 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).

*
* Description:

* NSH connections via Telnet. This function returns immediately after
* the daemon has been started.
*
* Input Parameters:
* family - Provides the IP family to use by the server. May be either
* AF_INET or AF_INET6. This is needed because both both may be
* enabled in the configuration.
*
* All of the other properties of the Telnet daemon are controlled by
* NuttX configuration settings.
*
* Returned Values:
* The task ID of the Telnet daemon was successfully started. A negated
* errno value will be returned on failure.

*
* Input Parameters:
* username/password - User credentials to be verified.

* common NSH logic is already initialized.
*
* Input Parameters:
* Standard task start-up arguments. Expects argc == 2 with argv[1] being

*
* Returned Values:
* EXIT_SUCCESS or EXIT_FAILURE
