    Fix 64bit arch issue in synaptics eventcomm.c
    
    In C, "1" is an integer, not an unsigned long. Thus (1 << 33) doesn't give
    you the 33th bit shift, but it's undefined.

    don't post motion events if the finger state is FS_UNTOUCHED
    
    Works around some buggy touchpads that report their position as things
    like 0,0; 0,ymax; etc. at the same time as they turn off the finger
    tool and/or touch indication.  This is particularly a problem when
    using the touchpad in absolute mode.

    config: don't autoprobe when device was set
    
    If device was already set, we were asked to handle that specific device
    and we should not go probing around. If we do, we might end up handling
    a device different from what the X server thinks we are handling, with
    dire consequences in case of hot plugging and unplugging.
    
    Without this patch, a situation such as the following can happen.
    
    A user has both a built-in laptop touchpad and a tablet such as the
    Wacom Bamboo Pen & Touch, that is also exposed as a touchpad.
    
    The tablet is plugged in before the server starts, and during setup the
    server calls the synaptic driver for the /dev/input/mouseX device
    corresponding to the touch device of the tablet; we end up in the
    autoprobe path even though `device' was set, and the driver scans
    /dev/input, where the first useful device it finds is the event device
    for the built-in touchpad.
    
    The driver starts managing the built-in touchpad, preventing future
    instances from managing it too, while the server thinks the driver is
    managing the tablet.
    
    When the user disconnects the tablet, the corresponding instance of the
    synpatics driver (which is actually managing the touchpad instead) is
    unloaded: the built-in touchpad stops working in X.
