Enrico Weigelt, metux IT consult 893f56f6b0 include: dix.h: add macros for request handlers and swapping 
add some macros for making request handlers easier:

    * REQUEST_HEAD_STRUCT() declares a struct and checks size (assuming
      length field already had been swapped)
    * REQUEST_FIELD_CARD16() swaps a CARD16 (word) if neccessary
    * REQUEST_FIELD_CARD32() swaps a CARD32 (dword) if neccessary

How to use them:

    1. move swapping of lengths field into the SProc*Dispatch() and drop it
       from the individual SProc*()'s
    2. put REQUEST_HEAD_STRUCT() ontop of each Proc*()
    3. add REQUEST_FIELD_*() below, for all fields to be swapped and
       drop their swapping from the SProc*()'s
    4. clean up unnecessary wrappers (SProc*()'s just be just call the
       corresponding Proc*() by now)
    5. let demux SProc just swap length field and call the normal Proc*Dispatch()

Enrico Weigelt, metux IT consult e7262542d5 (submit/cleanup-xi) Xi: use static reply struct init on declaration 
Make the code a bit easier to read by using initialization of the reply
structs, at the point of declaration. Most of them aren't written to later,
just passed into WriteReplyToClient(). Also dropping some useless zero
assignments (struct initializers automatically zero-out unmentioned fields).

Enrico Weigelt, metux IT consult d84af813a2 (submit/cleanup-xi) Xi: simplify dispatcher 
The dispatcher functions are much more complex than they're usually are
(just switch/case statement). Bring them in line with the standard scheme
used in the Xserver, so further steps become easier.

It's also much cleaner to use the defines from proto headers instead of
raw numbers.

Enrico Weigelt, metux IT consult 6da5284195 (submit/cleanup-damageext) damage: don't block requests when version not requested yet 
The original intention was negotiating versions before any further requests
can be processed, so requests that might become incompatible in future versions
still can be dispatched correctly. But practically that's never been the case:
there's just one major version, and it's unlikely that a new *major* version
(that might be incompatible with the current one, using same request codes for
different things) will come in the forseeable future.

So this extra logic isn't practically needed and just complicates dispatching.
Dropping it clears the road for further simplification of the dispatcher.

Enrico Weigelt, metux IT consult 8ef462c58a (submit/cleanup-damageext) damage: untwist Xinerma handling 
The diffenciation between Xinerama and single screen version is by tweaking
call vectors unncessarily complicated: it the only reason why these are
needed in the first place. Finally, it's just about one function, so it's
much easier just branching off in ProcDamageCreate() in case of Xinerama
is enabled.

This also clears the road for further simplification of the dispatcher.
