Instead of directly accessing the global screenInfo.screens[] array,
let everybody go through a little inline helper. This one also checks
for array bounds - if the screen doesn't exist, return NULL.

iterating over screen list via lambda-esque macros calls like this
DIX_FOR_EACH_SCREEN({
do_something
});
withing the body, the iterator variables `walkScreenIdx` and `walkScreen`
are defined and can be directly used (read-only). the code inside the body
is running in a separate scope.

these symbols aren't used by any external drivers (not even proprietary
Nvidia), so no need to keep them exported any longer:
* present_check_flips
* present_register_complete_notify
* present_can_window_flip
* uint32_t FakeScreenFps
Since it's not any *effective* ABI change, can go into current ABI-25 line.

The global (exported) serverGeneration field is `unsigned long`, while
many other places copy it and compare it two other integer types, eg.
plain `int` (which is signed). Even if it's unlikely ever reaching such
high number of generations that it will ever make trouble, it's still
a good idea to clean this up and use the same type everywhere.
For clearity, introducing a typedef `x_server_generation_t` which is
used everywhere, instead of raw `unsigned long`.

Previously we leaked stack when invalid enum parameters were
specified and caused __glGet*_size functions to return a 0 size.
Further, we read out-of-bounds (and leaked) when the input data was less
than 8 bytes (__glXDispSwap_GetFramebufferAttachmentParameteriv and
__glXDisp_GetRenderbufferParameteriv).
Now we only write a single element in the reply padding, and only when there
is a single element. This is what the Mesa client-side libGL expects, and
restores original GLX server behaviour, matching both pre-public (1996) SGI GLX
and XFree86 4.
The main risk of this change is if we have any error in element count or size;
previously it may not have mattered but now it does.
There are no piglit result changes from this modification using either mesa
libGLX or NVIDIA libGLX.
For performance considerations, an extra conditional and variable-length
memcpy has no meaningful impact on the indirect rendering pipeline cost.
There is still the possiblity to leak if our size checks allow an enum that
the GL implemention does not. Guarding against that requires zero-initializing
all temp storage, which wants re-evaluation of the blind 200-byte buffers
used for many calls and thus is a much bigger change.

Make it type-safe and a bit more obvious what it really does,
also adding some inline documentation. Since it's just some
bit shifting magic, it's qualified for inlining.
The CLIENT_ID() macro isn't used by any external modules, so the
new function doesn't need to be in a public header.

This header needs to be included first, otherwise things can easily get really
messed up. The current code only works by accident, because some other header
already including it early enough - but a subtle change in include order
can easy break it.
Thus, always make sure the header is really included first.

Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.
The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.
The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.
