Compression in qcow2 requires image length to be a multiple of the
cluster size. Lift this requirement by zero-padding the final cluster
when necessary. The virtual disk size is still not cluster-aligned, so
the guest cannot access the zero sectors.

Drop all the infrastructure for taddr properties (ie ones which
are 'hwaddr' sized). These are now unused, and any further desired
use would be rather questionable since device properties shouldn't
generally depend on a type that is conceptually variable based on
the target CPU. 32 or 64 bit integer properties should be used instead
as appropriate for the specific device.

Port the ARM CPU save/load code to use VMState. Some state is

to only have 16.

The versatile_pci PCI controller has a set of control registers which
handle the mapping between PCI and system address spaces. Implement
these registers (though for now they have no effect since we don't
implement mapping PCI space into system memory at all).
The most natural order for our sysbus regions has the control
registers at the start, so move all the others down one.

Implement the correct IRQ mapping for the Versatile PCI controller; it
differs between realview and versatile boards, but the previous QEMU
implementation was correct only for the first PCI card on a versatile
board, since we weren't swizzling IRQs based on the slot number.
Since this change would otherwise break any uses of PCI on Linux kernels
which have an equivalent bug (since they have effectively only been
tested against QEMU, not real hardware), we implement a mechanism
for automatically detecting those broken kernels and switching back
to the old mapping. This works by looking at the values the kernel
writes to the PCI_INTERRUPT_LINE register in the config space, which
is effectively the interrupt number the kernel expects the device
to be using.

Comments in the QEMU source code claim that the version of the PCI
controller on the VersatilePB board doesn't support the PCI I/O
region, but this is incorrect; expose that region, map it in the
correct location, and drop the misleading comments.
This change removes the only currently implemented difference
between the realview-pci and versatile-pci models; however there
are other differences in not-yet-implemented functionality, so we
retain the distinction between the two device types.
