    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.)

 "An experimental pseudocolor emulation layer.  Not fully completed,
 currently only works for 16bpp."  That was almost four years ago.
 It still doesn't work, only one driver even attempts to use it, it
 contains an ad-hoc implementation of damage, and should really be
 done up in Composite now anyway.

Use internal temp variable for swap macros. Make swaps/swapl type safe (introducing wrong_size check at build time).

 While working on this changeset, various spots got discovered where
 swapl or swaps was used on a wrong type, where byte swapping calls had
 been forgotten or done on the wrong variable.

 This backport at least includes changes from the following X.org

    Use correct swap{l,s} (or none at all for CARD8)

    Swapping the wrong size was never caught because swap{l,s} are macros.

    It's clear in the case of Xext/xres.c, that the author believed
    client_major/minor to be CARD16 from looking at the code in the first
    hunk.

    render: Fix byteswapping of gradient stops

    The function swapStops repeatedly swaps the color components as
    CARD16, but incorrectly steps over them as if they were CARD32.

    This causes half of the stops not to be swapped at all and some
    unrelated data be swapped instead.
