Enrico Weigelt, metux IT consult d708b28adc treewide: drop COMPOSITE symbol
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.

Enrico Weigelt, metux IT consult 56aad1434b mi: use CloseScreen hook
Wrapping ScreenRec's function pointers is problematic for many reasons,
so use the new screen close notify hook instead.

Enrico Weigelt, metux IT consult 479484b631 dix: add per-screen window position notify hook
Right now, extension specific actions on window positioning are implemented
by wrapping the ScreenRec's PositionWindow() proc pointer: the extensions are
storing the original pointer in their private data and putting in their own one.
On each call, their proc restores the original one, calls it, and switches back
again. When multiple extensions doing so, they're forming a kind of daisy chain.
(the same is done for lots of other procs)

While that approach is looking nice and elegant on the drawing board, it's
complicated, dangerous like a chainsaw and makes debugging hard, leading to
pretty blurred API borders.

This commit introduces a simple approach for letting extension hook into the
window positioning path safely, w/o having to care much about side effects
with the call chain. Extensions now can simply register their hook proc
(and an opaque pointer) and get called back - w/o ever having to mess with
the ScreenRec's internal structures. These hooks are called before the original
vector (usually handled by DDX/screen driver directly) is called.

No need for complicated wrapping/unwrapping: it's always just

Peter Hutterer 68c17477d2 mi: guard miPointer functions against NULL dereferences
Already in place for some functions, let's add it to most others.
The only function missing is miPointerSetPosition() which needs to
return the ScreenPtr and that one is unclear if we don't have a screen -
returning NULL will crash the caller(s) so let's wait for something to
trigger this bug before we try to fix it wrongly.

Peter Hutterer acbdd0ecdd mi: don't crash on miPointerGetPosition for disabled devices
If a device is disabled, its master device is forcibly reset to NULL but
unlike a floating device it doesn't have a sprite allocated. Calling
miPointerGetPosition for a disabled device thus crashes.

Avoid this by returning 0/0 for any device without a miPointer.
This is a quick fix only, a proper fix for this issue is rather more
involved.
