This patchset fixes the migration of sPAPR radix guests.
Migration of hash and radix guests individually has been tested on
TCG and KVM (P8 and P9 hosts). Changeover from HPT to RPT and vice versa
via reboot during migration isn't tested yet since it is possible
to test that currently only with TC
Add a "no HPT" encoding (using value -1) to the HTAB migration
stream (in the place of HPT size) when the guest doesn't allocate HPT.
This will help the target side to match target HPT with the source HPT
and thus enable successful migration.

Fix migration of radix guests by ensuring that we issue
KVM_PPC_CONFIGURE_V3_MMU for radix case post migration.

We need to be able to parse the 'filename' option for both rbd and iscsi,
because there may exist images in the wild that have json backing files,
that specify the filename argument.
Marking the series as RFC at least partially for the precedence given to
arguments; as written, these patches will

When enabling option parsing and blockdev-add for iscsi, we removed the
'filename' option. Unfortunately, this was a bit optimistic, as
previous versions of QEMU allowed the use of the option in backing
filenames via json. This means that without parsing this option, we
cannot open existing image

This series modifies the original ColdFire FPU implementation
to use floatx80 instead of float64 internally as this
is the native datatype for 680x0. I didn't keep the float64
type for ColdFire, but if someone thinks it's required I
can update this series in this way.
The series also adds the FPU

Ignoring this signal is especially important in qemu-nbd because

Sending a break on a serial console can be useful for debugging the
guest. But not all chardev backends support sending breaks (only telnet
and mux do). The chardev-send-break command allows to send a break even
if using other backends.
