On FDT, VMM can allocate IRQ from 0 for devices.
But on ACPI, the lowest range below 32 has to be avoided.

Now all crates use edition = "2018" then the majority of the "extern

to remain.

In order to support using Versionize for state structures it is necessary
to use simpler, primitive, data types in the state definitions used for
snapshot restore.

On AArch64, interrupt controller (GIC) is emulated by KVM. VMM need to
set IRQ routing for devices, including legacy ones.
Before this commit, IRQ routing was only set for MSI. Legacy routing
entries of type KVM_IRQ_ROUTING_IRQCHIP were missing. That is way legacy
devices (like serial device ttyS0) does not work.
The setting of X86 IRQ routing entries are not impacted.

Both GIC and IOAPIC must implement a new method notifier() in order to
provide the caller with an EventFd corresponding to the IRQ it refers
to.
This is needed in anticipation for supporting INTx with VFIO PCI
devices.

In anticipation for supporting the notifier function for the legacy
interrupt source group, we need this function to return an EventFd
instead of a reference to this same EventFd.
The reason is we can't return a reference when there's an Arc<Mutex<>>
involved in the call chain.

Currently the GED control is in a fixed I/O port address but instead use
an MMIO address that has been chosen by the allocator.

If a GED event of type 0x8 (for power button) is received notify the
guest OS that this button device has been activated.

Renamed this bitfield as it will also be used for non-hotplug purposes
such as synthesising a power button.

This can be uses to indicate to the caller that it should wait on the
barrier before returning as there is some asynchronous activity
triggered by the write which requires the KVM exit to block until it's
completed.
This is useful for having vCPU thread wait for the VMM thread to proceed
to activate the virtio devices.
