it is no longer needed because the code here is only used in the server.

just like upstream does

 This has already been started while replacing copyright info in file
 headers and has now been completed with this commit.

Remove defines of NEED_EVENTS and NEED_REPLIES because they are never
used anywhere.

Basically these three commits, but as they are newer and to not match
the code structure the patches have not been applied but replaced by
sed + manual intervention:

   Subject: Remove #define NEED_EVENTS and NEED_REPLIES

   A grep on xorg/* revealed there's no consumer of this define.

   Quote Alan Coopersmith:
   "The consumer was in past versions of the headers now located
   in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
   all the event definitions were only available if NEED_EVENTS were
   defined, and all the reply definitions required NEED_REPLIES.

   Looks like Xproto.h dropped them by X11R6.3, which didn't have
   the #ifdef's anymore, so these are truly ancient now."

 Casting return to (void) was used to tell lint that you intended
 to ignore the return value, so it didn't warn you about it.

 Casting the third argument to (char *) was used as the most generic
 pointer type in the days before compilers supported C89 (void *)
 (except for a couple places it's used for byte-sized pointer math).

 TryClientEvents already did this; this commit just moves the assignment
 one level down so that no event source has to worry about sequence
 numbers.

 ...No event source, that is, except XKB, which inexplicably calls
 WriteToClient directly for several events.

 This matches the test in TryClientEvents, and is a superset of tests
 done by the callers of these functions. The consequence of forgetting
 these tests is a server crash, so they're always desirable. In my
 opinion, it's better to not require the callers to remember to do these
 checks.

 For callers that don't do very much work before calling WriteToClient or
 WriteEventsToClient, I've removed the redundant checks.

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.

    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.

    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.
