Enrico Weigelt, metux IT consult d29600412f (1823) fb: 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)

Enrico Weigelt, metux IT consult 73c1ce2463 (!1909) fb: 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 ad1802015d (!1944) 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.
