In this revision, I'm now trying the approach of backend/frontend
split-ups for the affected IRQ chips. That means we keep a single qdev
device description but fork off specific logic early during device init.
The backends support this by providing hooks that user space and KVM
models can implement
More KVM-specific devices will come, so let's start with moving the
kvmclock into a dedicated folder.

Rename msix_supported to msi_supported and control MSI and MSI-X
activation this way. That was likely to original intention for this
flag, but MSI support came after MSI-X.

All LVTs are masked on reset, so the timer becomes ineffective. Letting
it tick nevertheless is harmless, but will at least create a spurious
trace event.

KVM is forced to disable the IRQ0 override when we run with in-kernel
irqchip but without IRQ routing support of the kernel. Set the fwcfg
value correspondingly. This aligns us with qemu-kvm.

The KVM in-kernel APIC model will reuse parts of the user space model
while providing the same frontend view to guest and most management

parts that will tell user space and KVM model apart. The backend offers
callback hooks for ini
To enable migration between accelerated and non-accelerated APIC models,
we will need to handle the timer saving and restoring specially and can
no longer rely on the automatics of VMSTATE_TIMER. Specifically,

Introduce the alternative i8259 backend that exploits KVM in-kernel

Add the basic infrastructure to active in-kernel irqchip support, inject
interrupts into these models, and maintain IRQ routes.
Routing is optional and depends on the host arch supporting
KVM_CAP_IRQ_ROUTING. When it's not available on x86, we looe the HPET as
we can't route GSI0 to IOAPIC pin 2.
This maintains the old imprecise access size handling.

The code is still in rough shape, but while we're on the topic of guest agents
I wanted to put out a working example of how exec functionality can be added
to qemu-ga to provide a mechansim for building arbitrarilly high-level
interfaces.
The hope is that by allowing qemu-ga to execute commands in

Allow sending up to 16 requests, and drive the replies to the coroutine
that did the request. The code is written to be exactly the same as
before this patch when MAX_NBD_REQUESTS == 1 (modulo the extra mutex
and state).

By attaching a client to an NBDRequest, we can avoid passing around the
socket descriptor and data buffer.
Also, we can now manage the reference count for the client in
nbd_request_get/put request instead of having to do it ourselved in
nbd_read. This simplifies things when coroutines are used.
