  Fixed bug 4436 - [OpenBSD] fix D-pad
  
  Thomas Frohwein
  
  Hi,
  
  If a gamepad lists the Dpad as 4 buttons (Dpad Up,Down, Left, Right) like with the Xbox 360 gamepad / XInput report descriptor used by OpenBSD (https://github.com/openbsd/src/blob/master/sys/dev/usb/uhid_rdesc.h#L184), this is not recognized by the SDL BSD backend and no hat or any other listing for the D-pad exists, e.g. in sdl2-jstest (https://gitlab.com/sdl-jstest/sdl-jstest).
  
  The attached diff fixes this and makes the D-pad on my Xbox 360 and Logitech F310 controllers usable. It adds a hat to nhats when usage HUG_DPAD_UP is found, reads the state of the D-pad buttons into array dpad[], and turns the value of dpad[] into an SDL hat direction (dpad_to_sdl()).
  
  Tested and works with Xbox 360 controller and Logitech F310 in XInput mode. Software-side tested with sdl2-jstest and Owlboy where this worked without problems or regressions.
  
  I don't know if this would be applicable to other *BSDs and don't have an install to test it with, therefore wrapped it in __OpenBSD__ ifdefs.
  
  Thanks,
