Negative: qemu_for_each_cpu() is discouraged, first_cpu and next_cpu are
okay. I need to send out my patch introducing CPU_FOREACH() macro based
on QTAILQ_FOREACH(), preview on qom-cpu-12 branch.

Markus wanted to rip out qemu_for_each_cpu() - also on that branch - but
mst wanted both to coexist.

Andreas
