    Refactor common code from XAddHost & XRemoveHost into single function
    
    On the Xlib side, the only real difference is the mode flag we send
    to the server with the address, so just make that an argument to the
    function with the common code for packing the address into the request.
    
    (Aside from labels, gcc 4.7.2 generates identical code before & after
     this change due to inlining, verified via diff of gcc -S output.)

    XSetModifierMapping: Use Data instead of GetReqExtra
    
    Handle arbitrary length data in the same fashion as other calls,
    avoiding need to ensure it fits all in the request buffer.
