    xen/kbdif: Add features to disable keyboard and pointer
    
    It is now not fully possible to control if and which virtual devices
    are created by the frontend, e.g. keyboard and pointer devices
    are always created and multi-touch device is created if the
    backend advertises multi-touch support. In some cases this
    behavior is not desirable and better control over the frontend's
    configuration is required.
    
    Add new XenStore feature fields, so it is possible to individually
    control set of exposed virtual devices for each guest OS:
     - set feature-disable-keyboard to 1 if no keyboard device needs
       to be created
     - set feature-disable-pointer to 1 if no pointer device needs
       to be created
    
    Keep old behavior by default.
