    Move each screen's root-window pointer into ScreenRec.

    Many references to the WindowTable array already had the corresponding
    screen pointer handy, which meant they usually looked like
    "WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
    keeping this information in a parallel array simplifies those
    expressions, and eliminates a MAXSCREENS-sized array.

    Since dix uses this data, a screen private entry isn't appropriate.

    xf86-video-dummy currently uses WindowTable, so it needs to be updated
    to reflect this change.
