Generally the cpu and non-FP helper files just want to manipulate the
softfloat flags. For this they can just use the -helpers.h include
which brings in a minimal number of inline helpers.

sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator. Evidence:
* It's included widely: in my "build everything" tree, changing
sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
objects (not counting tests and objects that don't depend on
qemu/osdep.h, down from 5400 due to the previous two commits).
* It pulls in more than a dozen additional headers.
Split stuff related to run state management into its own header
sysemu/runstate.h.
Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200. Touching new sysemu/runstate.h recompiles some 500 objects.
Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

We declare incomplete struct VMStateDescription in a couple of places

That's fine with me. However, the next commit will drop
migration/vmstate.h from a massive number of compiles. Move the

Let's add support for the AP-Queue interruption facility to the CPU
model.
The S390_FEAT_AP_QUEUE_INTERRUPT_CONTROL, CPU facility indicates
whether the PQAP instruction with the AQIC command is available
to the guest.
This feature will be enabled only if the AP instructions are
available on the linux host and AQIC facility is installed on
the host.
This feature must be turned on from userspace to intercept AP
instructions on the KVM guest. The QEMU command line to turn
this feature on looks something like this:
qemu-system-s390x ... -cpu xxx,apqi=on ...
or
... -cpu host
Right now AP pass-through devices do not support migration,
which means that we do not have to take care of migrating
the interrupt data:
