// Here we handle polling for the Host Input Authority and Golf modes. Pad data is "polled" from
// the most recent data received for the given pad. Passing pad_num < 0 will poll all assigned
// pads (used for batched polls), while 0..3 will poll the respective pad (used for MMIO polls).
// See GetNetPads for more details.
//
// If the local buffer is non-empty, we skip actually buffering and sending new pad data, this way
// don't end up with permanent local latency. It does create a period of time where no inputs are
// accepted, but under typical circumstances this is not noticeable.
//
// Additionally, we wait until some actual pad data has been received before buffering and sending
// it, otherwise controllers get calibrated wrongly with the default values of GCPadStatus.
