In particular update for the vmm-sys-util upgrade and all the other
dependent packages. This requires an updated forked version of
kvm-bindings (due to updated vfio-ioctls) but allowed the removal of our
forked version of kvm-ioctls.
The changes to the API from kvm-ioctls and vmm-sys-util required some
other minor changes to the code.

The vhost crate from rust-vmm is ready, which is why we do the switch
from the Cloud Hypervisor fork to the upstream crate.
At the same time, we rename the crate from vhost_rs to vhost.

This commit moves both pci and vmm code from the internal vfio-ioctls
crate to the upstream one from the rust-vmm project.

Now that ExternalDmaMapping is defined in vm-device, let's use it from
there.
This commit also defines the function get_host_address_range() to move
away from the vfio-ioctls dependency.

By moving the trait and its VFIO implementation out of vfio-ioctls, we
give anticipate for the move to the vfio-ioctls from rust-vmm.

This has been lagging behind on an older Rust version and we have
enough coverage from our Jenkins CI agent.

This removes the dependency on "tempdir" which in turn depends on the

The help information displayed for our `--disk` option is incorrect and

According to Intel's mnemonic (which is used by iced-x86) the first

The main idea behind this commit is to remove all the complexity
associated with TX/RX handling for virtio-net. By using writev() and
readv() syscalls, we could get rid of intermediate buffers for both
queues.
The complexity regarding the TAP registration has been simplified as
well. The RX queue is only processed when some data are ready to be
read from TAP. The event related to the RX queue getting more
descriptors only serves the purpose to register the TAP file if it's not
already.
With all these simplifications, the code is more readable but more
performant as well. We can see an improvement of 10% for a single
queue device.

This crate exposes the abililty for the VMM to set a file that events
should be written to. The event!() macro provides an interface to report
those events allowing the specification of an event source, an event
type and optional extra data. This will be written to the provided file
descriptor as JSON data.

We don't have an easy way to figure out if a GPA points to normal memory
or device memory, but the guest's normal memory regions shouldn't
overlap with device regions. We can simply try to do a normal memory
read / write, and proceed to do device memory read / write if that
fails.

OVMF would use string IO on those ports. String IO has not been
implemented, so that leads to panics.
Skip them explicitly in MSHV. Leave a long-ish comment in code to
explain the situation. We should properly implement string IO once it
becomes feasible / necessary.
