    Don't count legacy and MT axes twice
    
    The kernel exports both ABS_X and ABS_MT_POSITION_X (and a couple others)
    for a multi-touch capable device. For such devices, only count the axis once
    since we submit ABS_MT_POSITION_X through ABS_X.

    Add is_blacklisted_axis() helper
    
    The kernel exports a bunch of information as axis that shouldn't be an axis
    and we don't treat it as axis in the server. Add this helper instead of
    checking for the axis codes manually.
    
    No function change.

    Map ABS_MT_POSITION_X/Y into ABS_X/Y
    
    MT axes are the same as traditional axes, so one into the other so we get
    x/y coordinates regardless wich axes it comes from.

    Skip event posting for empty slots.
    
    ABS_MT_SLOT comes before any other events. The following order of events
    is common for protocol B devices (and mtdev):
    
    ...
    EV_SYN
    ABS_MT_SLOT        → posting here means we miss on the position information
    ABS_MT_POSITION_X
    ABS_MT_POSITION_Y
    ABS_MT_SLOT
    ABS_MT_POSITION_X
    ABS_MT_POSITION_Y
    EV_SYN
    
    Store the stot state as SLOT_EMPTY after posting an event (i.e. EV_SYN and
    ABS_MT_SLOT) and then don't post until the next slot/syn event.

    Ensure touchpad events are always processed with MT
    
    Without this change, an MT touchpad in relative mode could end a touch
    while not resetting the oldMask used to calculate relative values. This
    fix allows a Magic Trackpad to behave as a relative mode device again.

    Use MTDev for multitouch devices
    
    MTDev translates all multitouch devices to the slotted evdev protocol.
    This provides a clean and uniform interface and reduces message handling
    inside the input module and X.

    Use a new "Virtual Device" boolean property to mark virtual devices
    
    Use udev to check for the device's sysfs path, if it contains LNXSYSTM it's
    a kernel-emulated device. This property can then be used to determine if
    there are any real devices connected, allowing the desktop environment to
    e.g. turn off the touchpad whenever there's a mouse attached.
