Add ++/--/min/max to QSpecialInteger

Add both prefix and postfix versions of the increment/decrement
operators, and a static constexpr min/max which returns the
minimum/maximumm values that can be stored in the QSpecialInteger. These
latter functions are useful to define constants, e.g.:

    typedef quint8_be IPv4_TTL;
    static constexpr TTL_TO_DROP = IPv4_TTL::min();
