The old PCCONS driver only seems to be used on minimal install disks and
cannot coexist with newer ones (at least that's the feedback I've gotten

Both xlib as well as the Xserver use the same identifier "GC" for
different types. While on xlib it's just the numerical ID of a GC,
the xserver defines a struct for it by the same name. This is this
ugly and needs ridiculous hacks for Xserver code that needs xlib.
Easy to solve by just renaming the GC typedef to GCRec (consistent
with how we're naming other structs) and replacing GC* by GCPtr.

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.

Right now, extensions that need to be called after the CreateScreenResources
proc had been run, must wrap the screen proc vector directly (all of them
forming kind of daisy chain), and so - when called - temporarily restore the
previous one, call it, wrap again, and if the call was successful finally
doing it's own stuff. (same is done for many 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.
Instead introducing a simple approach for letting extension hook into a
post-CreateScreenResources callback list safely, w/o having to care much
about side effects with the call chain. Extensions now can simply register
their business logic and get called back - w/o ever having to mess with the
ScreenRec's internal structures.
Note that these hooks are executed *AFTER* the original CreateScreenResources()
proc had been called SUCCESSFULLY (returned TRUE), so callees can rely on
the DDX/driver had already done it's job.

Right now, extension specific pixmap destruction procedures are implemented
by wrapping the ScreenRec's DestroyPixmap() 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.
It's even getting worse: the proc also has to do ref counting, and only destroy
the pixmap if refconter reaching zero - that's all done in the individual screen
drivers. Therefore, all extensions must check for refcnt == 1, in order to know
when to really act.
This commit introduces a simple approach for letting extension hook into the
pixmap destruction safely, w/o having to care much about side effects with
the call chain. Extensions now can simply register their destructor proc
(and an opaque pointer) and get called back - w/o ever having to mess with
the ScreenRec's internal structures.
