    Encodes arguments in to Argument Paylods returning them to SilcBuffer.
    The `argv' is the array of the arguments, the `argv_lens' array of
    the length of the `argv' arguments and the `argv_types' array of
    the argument types of the `argv' arguments. The `argc' is the
    number of arguments.
