Any device inheriting from virtio-pci can specify a ROM file. This
option is provisioned by default with "efi-virtio.rom", but most
of the time, firmwares such as OVMF or seabios will already support
what is provided by this ROM file.
In order to reduce the "forced" dependency on such ROM file, govmm
should provide an empty path if the consumer of the library does not
provide one.
This patch reorganizes the list of devices, so that it gets easier to
list which devices inherit from virtio-pci, and then adds the romfile
option to every single device that support this option.

If we hotplug a nic with args mq=on, its qdisc will be mq by default.
This aligns with cold plug nics.

In order to be able to hotplug network devices such as vhost user
net, we need to be able to define a previously declared chardev as
a parameter of this new network device.

This commit adds a couple of negative test cases for qmp.go, one
which checks that failed commands return errors and the other
checks that QMPStart exits gracefully when passed an invalid
socket path.

With qemu 2.10, a write lock was added for qcow images that
prevents the same image to be passed more than once.
This can be over-ridden using the --share-rw option which is
desired for raw images.
This solves an issue with running Kata with devicemapper
using the privileged mode as in this case all devices on the host
are passed to the container using the block device associated
with the rootfs, causing it to be passed twice to qemu.

For machines types based on PCIe like q35, device addr and bus must be specified.
For machines types based on PCI like pc, device addr must be specified and bus
is optional since devices can be hot plugged directly on the root bus.

`getfd` receives a file descriptor via SCM rights and assign it a name,
this command is useful to send file descriptors from the host, and then
hot plug devices that needs file descriptors like vhost-vsock-pci devices.

`vhostfd` is used to specify the vhost-vsock device fd, and it holds
the context ID previously opened.
`disable-modern` is to disable the use of "modern" devices, by using virtio 0.9
instead of virtio 1.0. Particularly, this is useful when running the VM in a
nested environment.
