32ec9f2786 (1823) mi: replace xallocarray() by calloc() 
Only key difference that calloc(), in contrast to rellocarray(),
is zero-initializing. The overhead is hard to measure on today's
machines, and it's safer programming practise to always allocate
zero-initialized, so one can't forget to do it explicitly.

Cocci rule:

    @@
    expression COUNT;
    expression LEN;
    @@
    - xallocarray(COUNT,LEN)
    + calloc(COUNT,LEN)

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.

Related to #1782

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.

Closes #1782
