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.

It's always enabled for very long time now (at least since meson transition),
there doesn't seem to be any need to ever disable it again. So we can reduce
code complexity by removing all the ifdef's.

xwin relies on mi_priv.h being included indirectly, thus depending
on exact include within other header files. This can easily break if
something in other headers slightly changes.

No need for complicated wrapping/unwrapping: it's always just
miCreateResources() anyway - so we can call it directly.

This proc vector is optional (callers check for non-null) and neither fb nor

Both engines, GDI as well as DirectDraw, using the same screen init finish function,
so no need to keep indirection via per-engine callback pointer.
The winFinishScreenInitFB() can also be made static now.

The pointer to the window properties is currently inside the WindowOptional
structure, which may or may not exist at any given time. Thus, before accessing
those fields, at least need to check whether it exists, potentially need to
create it first.
Since a pointer is small (in relation to WindowRec) and windows having properties
is a pretty common, we can make our life much simpler here by moving the pointer
directly into WindowRec, so we don't need extra WindowOptionalRec allocation.
This also fixes an analyzer warning on potential NULL dereference issue:
| ../dix/property.c: In function ‘dixChangeWindowProperty’:
|../dix/property.c:343:37: warning: dereference of NULL ‘*pWin.optional’ [CWE-476] [-Wanalyzer-null-dereference]
| 343 | pProp->next = pWin->optional->userProps;

The include has become empty now. Not used by any external drivers,
so it can be dropped now.

call by extra mutex on windows only, while obviously not needed on

Xwin's DestroyPixmap proc just free()s the PixmapRec directly, w/o catering
for devPrivate's, so leaving a memleak. The correct DIX function for this

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.

Several places using _X_ATTRIBUTE_PRINTF macro from X11/Xfuncproto.h
but missing to include it, so it depends on other headers whether it's
included by mere accident, which quickly causes trouble if include order
changes. Cleaning that up by adding explicit include statements.

Since we already had to rename some of them, in order to fix name clashes
on win32, it's now time to rename all the remaining ones.
The old ones are still present as define's to the new ones, just for
