fd45e94510 vm-virtio: Add the ability to serialize a Queue
This commit relies on serde to serialize and deserialize the content of
a Queue structure. This will be useful information to store when

1b1a2175ca vm-migration: Define the Snapshottable and Transportable traits
A Snapshottable component can snapshot itself and
provide a MigrationSnapshot payload as a result.

A MigrationSnapshot payload is a map of component IDs to a list of
migration sections (MigrationSection). As component can be made of
several Migratable sub-components (e.g. the DeviceManager and its
device objects), a migration snapshot can be made of multiple snapshot
itself.
A snapshot is a list of migration sections, each section being a
component state snapshot. Having multiple sections allows for easier and
backward compatible migration payload extensions.

Once created, a migratable component snapshot may be transported and this
is what the Transportable trait defines, through 2 methods: send and recv.

42937c9754 vm-virtio: Add support for indirect descriptors
Indirect descriptors is a virtio feature that allows the driver to
store a table of descriptors anywhere in memory, pointing to it from a
virtqueue ring's descriptor with a particular flag.

We can't seamlessly transition from an iterator over a conventional
descriptor chain to an indirect chain, so Queue users need to
explicitly support this feature by calling Queue::is_indirect() and
Queue::new_from_indirect().

b2589d4f3f vm-virtio, vmm, vfio: Store GuestMemoryMmap in an Arc<ArcSwap<T>>
This allows us to change the memory map that is being used by the
devices via an atomic swap (by replacing the map with another one). The
ArcSwap provides the mechanism for atomically swapping from to another
whilst still giving good read performace. It is inside an Arc so that we
can use a single ArcSwap for all users.

Not covered by this change is replacing the GuestMemoryMmap itself.

This change also removes some vertical whitespace from use blocks in the
files that this commit also changed. Vertical whitespace was being used
inconsistently and broke rustfmt's behaviour of ordering the imports as
it would only do it within the block.

0f21781fbe cargo: Bump the kvm and vmm-sys-util crates
Since the kvm crates now depend on vmm-sys-util, the bump must be
atomic.
The kvm-bindings and ioctls 0.2.0 and 0.4.0 crates come with a few API
changes, one of them being the use of a kvm_ioctls specific error type.
Porting our code to that type makes for a fairly large diff stat.

587a420429 cargo: Update to the latest kvm-ioctls version
We need to rely on the latest kvm-ioctls version to benefit from the
recent addition of unregister_ioevent(), allowing us to detach a
previously registered eventfd to a PIO or MMIO guest address.

Because of this update, we had to modify the current constraint we had
on the vmm-sys-util crate, using ">= 0.1.1" instead of being strictly
tied to "0.2.0".

Once the dependency conflict resolved, this commit took care of fixing
build issues caused by recent modification of kvm-ioctls relying on
EventFd reference instead of RawFd.

c65ead5de8 vm-virtio: Trigger external map/unmap from virtio-iommu
This patch relies on the trait implementation provided for each device
which requires some sort of external update based on a map or unmap.

Whenever a MAP or UNMAP request comes through the virtqueues, it
triggers a call to the external mapping trait with map()/unmap()
functions being invoked.

Those external mappings are meant to be used from VFIO and vhost-user
devices as they need to update their own mappings. In case of VFIO, the
goal is to update the DMAR table in the physical IOMMU, while vhost-user
devices needs to update their internal representation of the virtqueues.

6d27cfb3b6 vm-virtio: Create virtio-net device
In order to provide connectivity through network interface between
host and guest, this patch introduces the virtio-net backend.

This code is based on Firecracker commit
d4a89cdc0bd2867f821e3678328dabad6dd8b767

It is a trimmed down version of the original files as it removes the
rate limiter support. It has been ported to support vm-memory crate
and the epoll handler has been modified in order to run a dedicated
epoll loop from the device itself. This epoll loop runs in its own
dedicated thread.
