Make the callbacks static members, so they can access private members.

Make m_pJoystick and GetDirectInput private.

Don't bail out on Update if the joystick fails, since we still have more
devices.  Just log--handle error conditions on our own.

Reduce Windows types in the interface; eventually it'll need to be
clean.

Remove unused Get*Device functions.
