Add a new size parameter to _WM_SetupMidiEvent() so that it knows
where to stop reading, and adjust its users properly. Fixes bug #175
(CVE-2017-11661, CVE-2017-11662, CVE-2017-11663, CVE-2017-11664.)
void _WM_do_control_dummy(struct _mdi *mdi, struct _event_data *data) {
#ifdef DEBUG_MIDI
    uint8_t ch = data->channel;
    MIDI_EVENT_DEBUG(__FUNCTION__, ch, data->data.value);
#else
    UNUSED(data);
#endif
    UNUSED(mdi);
}
