hpet/rtc: Rework RTC IRQ replacement by HPET
Allow the intercept the RTC IRQ for the HPET legacy mode. Then push
routing to IRQ8 completely into the HPET. This allows to turn
hpet_in_legacy_mode() into a private function. Furthermore, this stops
the RTC from clearing IRQ8 even if the HPET is in control.
This patch comes with a side effect: The RTC timers will no longer be
stoppend when there is no IRQ consumer, possibly causing a minor
performance degration. But as the guest may want to redirect the RTC to
the SCI in that mode, it should normally disable unused IRQ source
anyway.

Fix multiboot compilation
Commit
dd4239d6574ca41c94fc0d0f77ddc728510ffc57 broke multiboot. It replaced the
instruction "rep insb (%dx), %es:(%edi)" by the binary output of
"addr32 rep insb (%dx), %es:(%di)".
Linuxboot calls the respective helper function in a code16 section. So the
original instruction was automatically translated to its "addr32" equivalent.
For multiboot, we're running in code32 so gcc didn't add the "addr32" which
breaks the instruction.
This patch splits that helper function in one which uses addr32 and one which
does not, so everyone's happy.
The good news is that nobody probably cared so far. The bundled multiboot.bin
binary was built before the change and is thus correct.
Please also put this patch into -stable.

net: Fix hotplug with pci_add
The correct model type wasn't getting added when hotplugging nics with
pci_add.
Testcase: start VM with default nic type. In the qemu_monitor:
(qemu) pci_add auto nic model=virtio
This results in a nic hot-plug of the same nic type as the default.
This was broken in

Also changes the behaviour where no .init is defined for a
