This command was of minimal use before, now it is useless as the hpet
become a qdev device and is thus easily discoverable. We should
definitely not set query-hpet in QMP's stone, and there is also no good
reason to keep it for the interactive monitor.

This implements the HPET capability of routing IRQs to the front-side
bus, aka MSI support. This feature can be enabled via the qdev property
"msi" and is off by default.
Note that switching it on can cause guests (at least Linux) to use the
HPET as timer instead of the LAPIC. KVM users should recall that only
the latter is currently available as fast in-kernel model.

One HPET block supports up to 32 timers. Allow to instantiate more than
the recommended and implemented minimum of 3. The number is configured
via the qdev property "timers". It is also saved/restored so that it
need not match between migration peers.

By implementing this feature we can also remove a nasty way to kill qemu

Instead of keeping a static reference around, pass the state to

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.

Register the HPET as a sysbus device and create it that way. As it can
route its IRQs to any ISA IRQ, we need to connect it to all 24 of them.
Once converted to qdev, we can move reset handler and vmstate
registration into its hands as well.
