net_check_clients() prints this when an VLAN has host devices, but no
guest devices. It uses VLANState members nb_guest_devs and
nb_host_devs to keep track of these devices. However, -device does
not update nb_guest_devs, only net_init_nic() does that, for -net nic.
Check the VLAN clients directly, and remove the counters.

For some odd reason we sometimes hang inside KVM forever. I'd guess it's
a race condition where we actually have a level triggered interrupt, but
the infrastructure can't expose that yet, so the guest ACKs it, goes to
sleep and never gets notified that there's still an interrupt pending.
As a quick workaround, let's just wake up every 500 ms. That way we can
assure that we're always reinjecting interrupts in time.

Per default Linux doesn't come with a lot of storage adapters enabled on
Mac configurations. The one that's pretty much always present is the pmac-ide,
while the cmd64x is almost never included in any distribution.
So let's switch to use the MacIO based IDE controller. There is corresponding
OpenBIOS code to get interrupts working properly.

Our guest systems need to know by how much the timebase increases every second,
so there usually is a "timebase-frequency" property in the cpu leaf of the
device tree.
This property is missing in OpenBIOS.
With qemu, Linux's fallback timebase speed and qemu's internal timebase speed
match up. With KVM, that is no longer true. The guest is running at the same
timebase speed as the host.
This leads to massive timing problems. On my test machine, a "sleep 2" takes
about 14 seconds with KVM enabled.
This patch exports the timebase frequency to OpenBIOS, so it can then put them
into the device tree.

The interrupt code as is didn't really work for me. I couldn't even convince
Linux to take interrupt 9 in an interrupt-map.
So let's do this right. Let's map all PCI interrupts to 0x1b - 0x1e. That way
we're at least a small step closer to what real hardware does.
I also took the interrupt pin to line conversion from OpenBIOS, which at least
assures us we're compatible with our firmware :-).

The "Mac99" type so far defines a "U2" based configuration. Unfortunately,
there have never been any U2 based PPC64 machines. That's what the U3 was
developed for.
So let's split the Mac99 machine in a PPC64 and a PPC32 machine. The PPC32
machine stays "Mac99", while the PPC64 one becomes "Mac99_U3". All peripherals
stay the same.

The Uninorth PCI bridge requires different layouts in its PCI config space
accessors.
This patch introduces a conversion function that makes it compatible with
the way Linux accesses it.
I also kept an OpenBIOS compatibility hack in. I think it'd be better to
take small steps here and do the config space access rework in OpenBIOS
later on. When that's done we can remove that hack.

Some users prefer a single callback with length passed as parameter to
using b/w/l callbacks. It would maybe be cleaner to just pass length to
existing callbacks but that's a lot of churn. So for now add a wrapper.
For convenience use pcibus_t for address so a single callback can be
used for pci io and pci memory.
I did have to resort to preprocessor to reduce code duplication. It is
however slightly more straightforward, and better contained than what we
had with pci_host_template.h. Again, it would go away if we just passed
len to existing callbacks.
