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.

WriteToClient() already checks for zero-length buffer and does nothing
in that case. So we can make the code a bit easier to read and also
allow further simplification of reply submission by upcoming commits.

Collect up the puzzle piezes of the reply payload into to a temporary buffer,

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.

Some requests using different structs dependending on which protocol version
(v1 vs. v2) had been selected. That's is handled by coverting v1 structs into v2,
before proceeding with the actual handling.
The code flow of this is very complex and hard to understand. Cleaning this up
in several smaller steps, that are easier to digest.
This part moves the request payload structs (or pointers to them) into the
per-version branches. Within each branch following our usual scheme for
extension request handlers (eg. using the REQUEST*() macros and having a
pointer named `stuff` to the current request struct)

This part is splitting the huge request handlers into upper and lower half,
where the upper is doing the version check and converting v1 requests into v2,
while the lower one is doing the actual request processing, operating on the
struct pointer passed in from the upper one, instead of the client struct's
request buffer.

These dispatcher functions are much more complex than they're usually are
(just switch/case statement). Bring them in line with the standard scheme

In order to allow simplifying the reply send path, collect the reply
fragments into one buffer, instead of arbitrary number of WriteToClient()
calls. This also makes it much easier for potentially new purely packet-based
transports which (eg. binder) that would need their own stream parsing logic.
This xres function is an exceptionally hard case, since payload is constructed
step by step, and it's size only known when finished. The current way of the
fragment handling still has lots of room for improvement (eg. using very small
number of allocations), but leaving this for later exercise.
