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
 commits, listed in non-chronological order:

    Use internal temp variable for swap macros

    Also, fix whitespace, mainly around
        swaps(&rep.sequenceNumber)

    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.

    v2: dmx.c fixes from Keith.

    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.
