The function isn't used anymore, but still part of SDK/ABI. And it shouldn't
be used by drivers, ever. Marking it as deprecated now, so we can remove it later.
(it's also not present in recent proprietary NVidia drivers, btw)

This function is internal to DIX (used for assembling XQueryFont replies
and not used by any drivers (not even proprietary NVidia), and really
shouldn't ever called by them at all. It's been one the many victims of a
really unthoughtful mass export back 17 years ago.
That'S a necessary step for refactoring the RPC reply mechanics.
Since it's never used by any driver at all, we can easily to this change
within the current ABI level.

modesetting has a sort of broken concept of getting the cursor dimensions since 1f41320e1c, which causes issues on virtual machines and older AMD hardware. Our solution is to use SIZE_HINTS which is available in i915 since 2023 otherwise fallback to getting the cursor size provided by the driver, if a driver wants to have a more optimal cursor size, it is more than welcome to implement SIZE_HINTS in it's DRM interface.
Taken from my own fork of Xorg.

It is patch 1/7 of a series that provides a convenient way to specify
IgnoreABI and module search paths on a per-driver basis.
It adds #ifdef CONFIG_LEGACY_NVIDIA_PADDING wherever it should be but

Commit 3cb3024fea removed pScratchPixmap field
in ScreenRec, which broke legacy Nvidia (proprietary) drivers (470.x), thus
we should add an empty/dummy field here, to ensure correct padding. But this
would break ABI again - can't do that within minor release line.
As compromise, adding a *build time* option CONFIG_LEGACY_NVIDIA_PADDING for
this, so operators/packagers can opt-in to this change.
As it breaks ABI, the option is disabled by default until the next major release
and intended for EXPERTS ONLY who need nvidia390 or nvidia470 drivers.
Note that ALL DRIVERS should be rebuild if it is applied!
This compile-time option, along with the hacks needed to support it
in a non-abi-breaking way, should be droppen in the next major release.

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`.

Reduce complexity for things that really don't matter much:
The ddxBeforeReset() function is called when the Xserver going to reset
(new server generation). Right now, the only DDX really needing that is
Xwin, on all the others it's just no-op.
We've got an extra complicated build logic, which ifdef's out this all when
Xwin isn't built at all. The saving is extremely minimal - just skipping
few stub functions, which in most sessions aren't even called.
Therefore, get rid of this extra complexity that isn't giving us any
notable gain.
