* Function: StartMiniServer

* Parameters :

*
* Description:
* Initialize the sockets functionality for the
* Miniserver. Initialize a thread pool job to run the MiniServer
* and the job to the thread pool. If listen port is 0, port is
* dynamically picked
*
* Use timer mechanism to start the MiniServer, failure to meet the
* allowed delay aborts the attempt to launch the MiniServer.
*
* Return: int
* Actual port socket is bound to - On Success
* A negative number DLNA_E_XXX - On Error
