ShmScreenClose() needs to be registered as ScreenClose hook into
all screens - otherwise it won't be called and so we're missing
cleanup work.

Yet another step for getting rid of the unnecessarily complicated SProc*
machinery. Later, all those swap*() calls will be replaced by macros.

There is no explanation for these values, but the one we are
currently using doesn't work.
Use the values from vendor-speciffic drivers, which do work.

In the doListFontsWithInfo function in dixfonts.c, when a font alias is
encountered (err == FontNameAlias), the code saves the current state
and allocates memory for c->savedName.
If the malloc(namelen + 1) call fails, c->savedName remains NULL,
but c->haveSaved is still set to TRUE. Later, when a font is
successfully resolved (err == Successful), the code uses c->savedName
without checking if it is NULL, so there is potential null ptr
dereference. XNFalloc will check result of malloc and stop
program execution if allocation was failed.

Not used by any drivers, so no need to keep it in public SDK.
Since it's not used by any drivers, effectively no ABI change, so
can be safely done within ABI-25.

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.

have it in public SDK header.

CoreEnterLeaveEvent calls FixUpEventFromWindow with a pointer to a stack-allocated xEvent structure, which may get later casted into an xXIDeviceEvent*, with writes done by FixUpXI2DeviceEventFromWindow at an offset larger than sizeof(xEvent). This code-path is protected by xi2_get_type() but the following warning is generated by building with -O3 and LTO:
In function 'FixUpXI2DeviceEventFromWindow',
inlined from 'FixUpEventFromWindow' at ../dix/events.c:2716:13,
inlined from 'CoreEnterLeaveEvent' at ../dix/events.c:4679:5:
../dix/events.c:2628:48: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=]
2628 | ((xXIEnterEvent *) event)->same_screen =

../dix/events.c: In function 'CoreEnterLeaveEvent':
../dix/events.c:4652:12: note: at offset 48 into destination object 'event' of size 32
4652 | xEvent event = {
| ^
This PR suppresses this warning, by tracking the level of the event (ie., core event, XI or XI2) and ensuring that fix-up is performed only on XI2 events.

No need to have whole extra functions for just a few LoC, and in the
future the whole thing will become more simplified by generic macros.

Move the callbacks directly into DIX, since it's actually core infrastructure.
Also simplifying the whole machinery, by just using a simpel CallbackListPtr.

This function is really doing nothing except of calling into the
actual request handler, so not needed at all.
