There are no other dependencies of device assignment except for
CONFIG_KVM and an x86 target. So there is also no point in controlling
this feature via configure.

Use kvm_irqchip_add_msi_route and introduce kvm_irqchip_update_msi_route
to set up the required IRQ routes for MSI-X injections. This removes the
last direct interaction with the IRQ routing API of the KVM kernel so
that we can remove/unexport related services.

Introduce three new KVM services, kvm_device_intx/msi/msix_deassign, to
release assigned interrupts. These no longer require to pass
pre-initialized kvm_assigned_irq structures but only request required
parameters.
To trace which type of interrupt is currently assigned, use a new enum
AssignedIRQType instead of KVM constants.

In contrast to the old wrappers, the new ones only take the required
parameters instead of a preinitialized kvm_assigned_pci_dev structure.
We also move the dev_id generation into kvm_device_pci_assign and store
the result in the AssignedDevice structure. It will serve as handle for
all upcoming kvm_device_* functions.
While refactoring these services, start moving KVM services where they
should finally end up in upstream QEMU: in the i386-specific KVM layer.

While running in the usermode emulator all of the required*
MIPS32r2 RDHWR hardware registers should be accessible (the
Linux kernel enables access to these same registers). Note
that these registers are still enabled when the MIPS ISA is
not release 2. This is OK since the Linux kernel emulates
access to them when they are not available in hardware.
* There is also the ULR register which is only recommended
for full release 2 compliance. Incidentally, accessing
this register in the current implementation works fine
without flipping its access bit.

At some point in the past, the OPEN event was changed to be issued from a
bottom half. This creates a small window whereas a data callback registered in
init may be invoked before the OPEN event has been issued.
This is reproducible with:
echo "{'execute': 'qmp_capabilities'}" | qemu-system-x86_64 -M none -qmp stdio
We can fix this for the monitor by moving the parser initialization to init.
The remaining state that is set in OPEN appears harmless.

This allows any QEMU binary to be executed with:
$QEMU_BINARY -M none -qmp stdio
Without errors from missing options that are required by various boards. This
also provides a mode that we can use in the future to construct machines
entirely through QMP commands.

The preceding commits fixed misuses of FROM_SYSBUS() that led people to
add a bogus busdev field. For qdev the field order was less relevant but
for QOM the PCIHostState field (including the SysBusDevice actually
initialized with a value) must be placed first within the state struct.
To facilitate accessing the PCIHostState fields, derive all PCI host
bridges from TYPE_PCI_HOST_BRIDGE rather than TYPE_SYS_BUS_DEVICE.
We can now access PCIHostState QOM-style, with PCI_HOST_BRIDGE() macro.
