    Remove xevie support
    
    The Xevie extension was removed from X.org in 2008:
    
      https://freedesktop.org/wiki/Software/XEvIE/
    
    * XEvIE has been removed from HEAD on Wed Oct 22:
      http://cgit.freedesktop.org/xorg/xserver/commit/?id=f4036f6ace5f770f0fe6a6e3dc3749051a81325a
    
    > It's unmaintained and has been broken for quite a while; MPX finally
    > smashed it completely.
