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.

This feature is stable and there is no need for this to be behind a

Use a new feature called "pvh_boot" to enable using the PVH boot
protocol if the guest kernel supports it. The feature can be enabled
by building with:
cargo build [--release] --features "pvh_boot"
Once performance has been evaluated, this can be made part of the
default set of features so that any guest that supports it boots
using PVH as the preferred option as is the case in QEMU.

This change enables vhost_user_fs to process multiple requests in
parallel by scheduling them into a ThreadPool (from the Futures
crate).
Parallelism on a single file is limited by the nature of the operation
executed on it. A recent commit replaced the Mutex that protects the
File within HandleData with a RwLock, to allow some operations (at
this moment, only "read" and "write") to proceed in parallel by
acquiring a read lock.
A more complex approach was also implemented [1], involving
instrumentation through vhost_user_backend to be able to serialize
completions, reducing the pressure on the vring RwLock. This strategy
improved the performance on some corner cases, while making it worse
on other, more common ones. This fact, in addition to it requiring
wider changes through the source code, prompted me to drop it in favor
of this one.

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.

The goal here is to ensure that CLI and OpenAPI both behave as closely
as possible, and also that they behave as expected.
Leveraging the reorganization of the code, we can now compare two
VmConfig structures generated from one CLI entry on one side, and from
an OpenAPI entry (JSON payload) on the other side.

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.

Create a vhost-user-blk backend using vhost-user-backend and following
the conventions established by the existing vhost-user-net
implementation.
This backend is based on https://github.com/slp/vhost-user-backend,
but a bit simplified, making it closer to the original implementation
in Firecracker. The main features missing are EVENT_IDX, support for
asynchronous I/O and multiqueue, but it's still fully functional and
provides a good starting point for evolving it into a more complete
implementation.
