All callers of bdrv_img_create() pass in a size, or -1 to read the
size from the backing file. We then set that size as the QemuOpt
default, which means we will reuse that default rather than the
final parameter to qemu_opt_get_size() several lines later. But
it is rather confusing to read subsequent checks of 'size == -1'
when it looks (without seeing the full context) like size defaults
to 0; it also doesn't help that a size of 0 is valid (for some
formats).
Rework the logic to make things more legible.

The "sclpquiesce" device is just an internal device that should not be
created by the user directly. Though it currently does not seem to cause
any obvious trouble when the user instantiates an additional device, let's
better mark it with user_creatable = false to avoid unexpected behavior,
e.g. because the quiesce notifier gets registered multiple times.

A TYPE_SCLP_CPU_HOTPLUG device for handling cpu hotplug events
is already created by the sclp event facility. Adding a second
TYPE_SCLP_CPU_HOTPLUG device via -device sclp-cpu-hotplug creates
an ambiguity in raise_irq_cpu_hotplug(), leading to a crash once
a cpu is hotplugged.
To fix this, disallow creating a sclp-cpu-hotplug device manually.

The "sclp" device is just an internal device that can not be instantiated
by the users. If they try to use it, they only get a simple error message:
$ qemu-system-s390x -nographic -device sclp
qemu-system-s390x: Option '-device s390-sclp-event-facility' cannot be
handled by this machine
Since sclp_init() tries to create a TYPE_SCLP_EVENT_FACILITY which is
a non-pluggable sysbus device, there is really no way that the "sclp"
device can be used by the user, so let's set the user_creatable = false
accordingly.

If we fail to set a proper TOD clock on the target system, this can
already result in some problematic cases. We print several warn messages
on source and target in that case.
If kvm fails to set a nonzero epoch index, then we must ultimately fail
the migration as this will result in a giant time leap backwards. This
patch lets the migration fail if we can not set the guest time on the
target.
On failure the guest will resume normally on the original host machine.

Commit e996583eb3 ("s390x/css: activate ChannelSubSys migration",
2017-07-11) was supposed to enable css migration for virtio-ccw
machines starting 2.10, but it ended up effectively enabling it
only for 2.10 as the registration of the appropriate VMStateDescription
happens in ccw_machine_2_10_instance_options which does not get
called for machines more recent than 2_10.
Let us move the corresponding chunk of code (which conditionally enables
the migration based on the value of the corresponding class property) to
ccw_init, which is called for each virtio-ccw machine instance.

The problem is, that the current implementation places unrealistic and
arbitrary constraints on the length of writes to the device (that is the
outbound requests), by asserting ccw.count being such that that even the
worst case escaped payload will fit an more or less arbitrary sized
buffer. Actually on protocol level there is nothing to justify such
a limitation.
Another strange thing is the return value which more or less reflects
the size (written) after escaping instead of before escaping. This
is strange, because this return value is used to calculate SCSW.count.
Let us teach 3270 how to deal with arbitrary long writes.

The STFLE bits for the MSA (extension) facilities simply indicate that
the respective instructions can be executed. The QUERY subfunction can then
be used to identify which features exactly are available.
Availability of subfunctions can also vary on real hardware. For now, we
simply implement a CPU model without any available subfunctions except
QUERY (which is always around).
As all MSA functions behave quite similarly, we can use one translation
handler for now. Prepare the code for implementation of actual subfunctions.
At least MSA is helpful for now, as older Linux kernels require this
facility when compiled for a z9 model. Allow to enable the facilities
for the qemu cpu model.
