* This function parses a xml file containing tvdb language data,

* The xml data will be downloaded, or (optionally) read from a file.
*
* If you no longer need the data, you'll have to free the hashtable
* (with eina_hash_free()), but not the data in the table.
*
* @param lang_file_path Path to a XML file containing TVDB's supported languages.
* This allows to provide a custom XML language file.
* It is recommended to pass NULL. In this case the languages.xml file provide with
* etvdb will be used and, if not available, the languages will be retrieved online.
*
* @return a pointer to a Eina hashtable on success, NULL on failure
