Integers are transmitted two ways: arbitrary precision signed integers or
arbitrary precision unsigned integers. There is no int8, int16 etc.
discrimination in the gob format; there are only signed and unsigned integers. As
described below, the transmitter sends the value in a variable-length encoding;
the receiver accepts the value and stores it in the destination variable.
