If the user fails to specify 'chardev' or 'shm' then we cannot continue.
Exit right away so that we don't invoke shm_open(3) with a NULL pointer.
It would be nice to replace exit(1) with error returns in the PCI device
.init() function, but leave that for another patch since exit(1) is
currently used elsewhere.

Drop ISADeviceClass::init and the resulting no-op initfn and let
children implement their own realizefn. Adapt error handling.
Split off an instance_init where sensible.

Remove some code duplication by adding a
function to look up the fw cfg file.
This way, we don't need to duplicate same strings everywhere.
Use by both fw cfg and pvpanic device.

This lets seabios patch the corresponding SSDT entry.
Also add fw_cfg object to /machine/fw_cfg so we can reference

pvpanic device is used to send guest panic event from guest to qemu.
When guest panic happens, pvpanic device driver will write a event
number to IO port 0x505(which is the IO port occupied by pvpanic device,
by default). On receiving the event, pvpanic device will pause guest
cpu(s), and send a qmp event QEVENT_GUEST_PANICKED.

This adds a new device that we can use for testing PCI PIO and MMIO, with and
without ioeventfd in different configurations. FAST_MMIO will be added if/when
kvm supports it. Also included are minor cleanups in kvm APIs that it needs.
