Enrico Weigelt, metux IT consult 7a64dadeb8 (1626) Xext: xvmc: 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.

Enrico Weigelt, metux IT consult 7a706b5e1e (1613) test: Xi: make sure client swapped flag is reset
Some test cases are recycling the ClientRec between swapped/unwapped runs.
Make sure the Client's swapped flag is always reset in those cases.

Enrico Weigelt, metux IT consult 7f43b09aa3 (1613) 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).

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 f83b8cceb6 (1623) xkb: ProcXkbGetKbdByName(): collect sub-replies in buffer and write at once
Instead of dozens of little WriteToClient() calls, collect the sub-replies in
a buffer and send the whole reply out at once. This also allows more upcoming
simplifications in the send path.

Enrico Weigelt, metux IT consult 8ba5c85fa2 (1623) xkb: split XkbSendGeometry()
This function is a funny beast: it assembles and writes out an xkbGetGeometryReply,
called in two different cases, ProcXkbGetGeometry() as well as ProcXkbGetKbdByName().
In the latter case the whole reply is contained in another one. That's the reason
why it's payload size is computed separately - the caller must know that in order
to set up the container's reply size correctly.

As preparation for upcoming simplifications of the reply send path, splitting off
this function into pieces: XkbAssembleGeometry() just assembles the reply payload,
while it's callers now responsible for preparing the request header and writing
out both pieces.

caller. So instead let the caller pass in the relevant fields and do the

Enrico Weigelt, metux IT consult b95fba219c (1623) xkb: XkbSendIndicatorMap(): little simplification
A bit simplification in code flow.
The extra length check (did we write as much as intended?) isn't necessary,
since the buffer size is computed by the very same data before this
function is called.

Hint: the size computation must be done before calling this one, because
the reply might be encapsulated in another one (xkbGetKbdByName).
