dae0b2ef72 vm-virtio: Implement the Pausable trait for all virtio devices
Due to the amount of code currently duplicated across virtio devices,
the stats for this commit is on the large side but it's mostly more
duplicated code, unfortunately.

Migratable and Snapshotable placeholder implementations are provided as
well, making all virtio devices Migratable.

6566c739e1 vm-virtio: Add IOMMU support to virtio-vsock
Adding virtio feature VIRTIO_F_IOMMU_PLATFORM when explicitly asked by
the user. The need for this feature is to be able to attach the virtio
device to a virtual IOMMU.

dac7737919 vm-virtio: Implement reset() for virtio-vsock
The virtio specification defines a device can be reset, which was not
supported by this virtio-vsock implementation. The reason it is needed
is to support unbinding this device from the guest driver, and rebind
it to vfio-pci driver.

475e487ac3 vmm: Create vsock backend
This commit relies on the new vsock::unix module to create the backend
that will be used from the virtio-vsock device.

The concept of backend is interesting here as it would allow for a vhost
kernel backend to be plugged if that was needed someday.

22f91ab3a2 vm-virtio: Move vsock to its own module
There is a lot of code related to this virtio-vsock hybrid
implementation, that's why it's better to keep it under its
own module.
