evdev 2.2.5

Regression:
    If a user has multiple buttons mapped to the same button number, the
    number of buttons counted is set to a wrong value.  e.g. a button
    mapping of 1 1 1 for a mouse with three buttons would only initialize 1
    button to the X server.

    In the future, the user cannot change this button mapping as the server
    only knows about one button.

The user-supplied button map (option ButtonMapping) shouldn't matter when
counting the buttons. Only the driver-internal mapping (BTN_0 -> button 1,
etc.) matters.
