In order to implement the new error handling and debugging
mechanism for command handlers, we need to change the cmd_new()
callback to return a value.

This commit introduces cmd_new_ret(), which returns a value and
will be used only temporarily to handle the transition from
cmd_new().

That is, as soon as all command handlers are ported to cmd_new_ret(),
it will be renamed back to cmd_new() and the new error handling
and debugging mechanism will be added on top of it.

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.
