Simplify writing reply payload into just one block.
This also makes further simplifications by subsequent patches easier.

Simplify reply buffer in SELinuxSendItemsToClient() by putting it on stack.
No need to go through heap and free it later, if the compiler can do all
the work for us.
This also allows further generalizations of reply sending code by upcoming
commits.

Move extra complexity out of the dispatch functions, so they're
really just switch/case statements calling the actual handler procs.
Preparation for further steps.

These 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.

Collect up the puzzle piezes of the reply payload into to a temporary struct,
so we can send it as one block. This allows for further simplifications by
subsequent commits.

The payload lengths is already known, so we can easily collect the data
in a stack buffer and only need one WriteToClient() operation.
This also clears the road for further simplification/unification of the
reply sending code, coming with follow-up commits.

Simplify sending by collecting in a local scoped buffer, so only one
WriteToClient() call is needed. This also makes further simplifications
by upcoming patches easier.

The way it's currently done, indirectly via macros calling dedicated
functions, is unnecessarily complicated. Simply inline it, just like
(almost) all the other extensions are doing it.

The ProcVidModeGetAllModeLines() is a bit complicated, because reply structs
differ depending the active protocol version. In order to make it easier to
understand and allow further simplification of the request/reply marshalling
(see ticket #1701), splitting the two protocol versions into separate functions.
Also collecting the whole payload in a stack buffer (size is already known
anyways), in order to save arbirary number of individual WriteToClient() calls,
but send out the whole reply in one pass, which in turn allows further
simplifications in the sending path.

We can simply call SwapLongs() before writing out the CARD32 arrays.
No need using for complicated call back logic.

Semantically these are separate values in each branch any only used there,
so it's a bit more clean to move the declaration into the branches.

The WriteSwappedDataToClient() already checks whether client is swapped
and directly calls WriteToClient() if it's not.

Coherently moving all reply struct decls and assignments into static
initialization right at declaration, just before it is getting byte-
swapped and sent out. Zero-assignments can be dropped here, since the
compiler automatically initializes all other fields to zero.
