pc-bios/s390-ccw: avoid floating point operations
Some gcc versions (e.g. Fedora 22 gcc 5.1.1) seem to use floating
point registers for spilling and filling of general purpose registers.
As the BIOS does not activate the AFP register setting of CR0 this can
cause data exception program checks.
Disallow floating point in the BIOS as a simple solution.

s390x/gdb: expose virtualization specific registers
Let's expose some virtual/fake registers as virtualization specific
registers.

s390x: set missing parent for hotplug and quiesce events
Existing code missed to set a parent for the quiesce and hotplug event.
While this didn't matter in practise, new introspection APIs basically now
do an object_unref(object_new(T)), which loops forever.
When trying to remove the event facility bus, the code tries to
unparent all childs on the bus, so they are properly deleted and therefore
removed.
As object_unparent() on these child devices doesn't work, as there is no parent,
we loop forever.
Let's fix this by adding the event facility as a parent. Also switch from
object_initialize to object_new, so the only valid reference is in fact the
parent property. This makes it more obvious when the device (state) is actually
gone (and how the reference counting works).

s390x: rename io_subsystem_reset -> subsystem_reset
According to the Pop:
"Subsystem reset operates only on those elements in the configuration
which are not CPUs".
As this is what we actually do, let's simply rename the function.

s390: fixes
Some fixes all over the place:
- ccw bios and gcc 5.1 (avoid floating point ops)
- properly print vector registers
- sclp and sclp-event-facility no longer hang on object_unref(object_new(T))
- better name for io_subsystem_reset
One feature
- the gdb server now exposes several virtualization specific register
