Reworked XInput and DirectInput joystick code.
Now multiple XInput controllers map correctly to device indexes instead of grabbing the first available userid, and are completely separated out from DirectInput. Also, the hardcoded limitation on number of DirectInput devices is gone. I don't expect there to really ever be more than eight joysticks plugged into a machine, but it was a leftover limitation for a static array we didn't actually use anymore. Fixes Bugzilla #1984. (etc?)
