Enrico Weigelt, metux IT consult 9cfb86f916 (!1909) os: use calloc() instead of malloc()
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.

Enrico Weigelt, metux IT consult 5a5ef53966 (!1714) dix: add CreateScreenResources callback mechanism
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.
