That's what 2/4 resolves. My reasoning was that this should be an
uncontroversial code-sharing change since, for good or bad,
qemu-common.h happens to be the place where this is defined today.

Whether to move it to qemu-types.h as proposed or to a new qemu-stdio.h
affects more than just the core CPU and thus me as maintainer and
requires careful mingw32 etc. testing.

If we find an agreeable solution by tomorrow for how/where to do it, sure!
