By relaxing the dependency to ">=0.6" this crate can be used in projects
using newer vm-memory without pulling in duplicates of the crate.

crates.io does not allow publishing crates which have wildcards in
their dependencies. We had one for "serial_test", so replace the
wildcard pointing it to the current major/minor ("0.5").

Add a vhost-vdpa in-kernel implementation of VhostVdpa trait.
Tests are serialized since the device supports only a single user
at a time.

Add new VhostVdpa trait to handle vhost-vdpa devices and a new
vhost-vdpa building feature.
vhost-vdpa devices is based on vhost backend, for this reason
VhostVdpa trait requires VhostBackend.

Converting arbitrary bytes into an arbitrary Rust value is unsafe.
For example, it's unsafe to create a String that isn't valid UTF-8.
But the various internal recv* functions didn't restrict their return
types enough to enforce this invariant, making them unsafe without
being properly marked.
To fix this, we tighten up the bounds of the functions to enforce that
their return types are ByteValued, meaning that they can only be used
to create types that are safe to initialize with arbitrary data such
as might be received over a socket.
It's worth asking how these functions could have been unsafe in the
first place, since they don't contain any unsafe blocks themselves.
The answer is that the functions that recv into iovecs are also unsafe
but not correctly marked. I'm preparing further patches to fix that
up, but it's a lot of work so I've separated out this change in the
hope of getting it in first and making the diff for the next one
smaller.
This internal tightening shouldn't result in any public API changes.

The inflight I/O tracking feature is useful for handling crashes and
disconnections from the backend. It allows the backend to rely on a
buffer that was shared earlier with the VMM to restore to the previous
state it was before the crash.
This feature depends on the availability of the protocol feature
VHOST_USER_PROTOCOL_F_INFLIGHT_SHMFD, and it implements both
VHOST_USER_GET_INFLIGHT_FD and VHOST_USER_SET_INFLIGHT_FD messages.

The auto-generated vhost binding is small, it would be better
to include it into the vhost crate instead of building another
dedicated crate for it.

These interfaces are derived from the firecracker and crosvm projects.
They may be extended when enable support of vhost-user protocol.
