 * config_parse_buf()
 *
 * Parameters:
 *	cfg_node	Ptr to the generated parse tree of XML cfg string
 *	msg_list	List needed by parser routine if errors encountered
 *	buf		XML cmd string that needs to be parsed.
 *
 * This function is a generic version of mms_config_parse.
 * It is designed so that
 * a user does not have to create a input routine. The only requirement is
 * that the XML string they need parsed be a character string.
 *
 * Return Values:
 *	0	If config parsed without errors.
 *	1	If config parsed with errors.
 *	-1	If unable to allocate enough memory for parse tree.
