    mouse: skip button mappings only for core devices.
    
    Since X server 1.4, devices are unlikely to be marked as IsXExtensionDevice.
    More common is IsXExtensionKeyboard or IsXExtensionPointer. However, with
    many pointer devices also having keys (e.g. most wireless combos) a check
    for IsXExtensionPointer is unreliable.
    
    In gsd-mouse-manager, skip the XInput button mapping only if the device is a
    core device. Otherwise, test for buttons.
