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.

When iterating screen lists, consistently use the same variable name
`walkScreen` for holding current screen pointer everywhere.

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`.

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.

The symbol controls whether to include dix-config.h, and it's always set,
thus we don't need it (and dozens of ifdef's) anymore.
This commit only removes them from our own source files, where we can
guarantee that dix-config.h is present - leaving the (potentially exported)
headers untouched.

This updates rootless to treat pixmaps consistently with COMPOSITE,
using the screen_x and screen_y values rather than doing hacky math.
This will allow for proper bounds checking on a given PixmapRec.

This should no longer be necessary since we only support implementations
that handle preserving the bits across resize. We can use
RootlessNoCopyWindow instead.

I don't see a reason why we would want to preserve pixels that are going to
not be visible anyways. The rootless implementation already handles
preserving the relevant bits for us.

If none of the four corners is fixed, we can use RL_GRAVITY_NORTH_WEST weighting

The implementation owns the pointer during RootlessStopDrawing and
RootlessStartDrawing and is free to (does) change it. Rootless
cannot assume ownership of this memory region. This is possibly
the cause of some hard to diagnose crashes in XQuartz over the
years.

In both cases we check for width > 0 just above, and the variable is not

Slightly simplifies the callers since they don't need to check for
non-NULL anymore.
I do extremely hate the workarounds here to suppress misprite taking the
cursor down though. Surely there's a better way.

gcc quite correctly complains about this:

So that'd crash if you ever got there. RegionNull will do almost the
same thing only without the free(), so let's do that instead; it might
still not be an entirely sane way to recover, but it at least won't
crash.

ROOTLESS_RESIZE_GRAVITY is an optimization, so let's default it to off
unless the backing window system is known to support it.
ROOTLESS_PROTECT_ALPHA looks like it has different values for xquartz
and win32, but hilariously rootlessGC.c merely checks if it is defined,
not what the value is. It's effectively the more conservative path
anyway, so let's just turn it on.
