    Rewrite xlsclients to use XCB, avoiding many (many) round trips
    
    This version spends bandwidth to reduce latency; in particular, it
    aggressively calls query_tree before the answer to get_property(WM_STATE) is
    available.
    
    Even on my local box, this version is 4-10 times faster (30ms typical, vs
    200ms typical for Xlib). I get similar results over the local network.
    
    At least one person reports this version takes less than 2 seconds over ssh,
    vs over a minute for the Xlib version (~30x faster).
