a423bf13ad virtio: Port codebase to the latest virtio-queue version
The new virtio-queue version introduced some breaking changes which need
to be addressed so that Cloud Hypervisor can still work with this
version.

The most important change is about removing a handle to the guest memory
from the Queue, meaning the caller has to provide the guest memory
handle for multiple methods from the QueueT trait.

One interesting aspect is that QueueT has been widely extended to
provide every getter and setter we need to access and update the Queue
structure without having direct access to its internal fields.

This patch ports all the virtio and vhost-user devices to this new crate
definition. It also updates both vhost-user-block and vhost-user-net
backends based on the updated vhost-user-backend crate. It also updates
the fuzz directory.

0162d73ed8 virtio-queue: Update crate based on latest rust-vmm/vm-virtio
This crate contains up to date definition of the Queue, AvailIter,
DescriptorChain and Descriptor structures forked from the upstream
crate rust-vmm/vm-virtio 27b18af01ee2d9564626e084a758a2b496d2c618.

The following patches have been applied on top of this base in order to
make it work correctly with Cloud Hypervisor requirements:

- Add MSI vector field to the Queue

  In order to help with MSI/MSI-X support, it is convenient to store the
  value of the interrupt vector inside the Queue directly.

- Handle address translations

  For devices with access to data in memory being translated, we add to
  the Queue the ability to translate the address stored in the
  descriptor.
  It is very helpful as it performs the translation right after the
  untranslated address is read from memory, avoiding any errors from
  happening from the consumer's crate perspective. It also allows the
  consumer to reduce greatly the amount of duplicated code for applying
  the translation in many different places.

- Add helpers for Queue structure

  They are meant to help crate's consumers getting/setting information
  about the Queue.

These patches can be found on the 'ch' branch from the Cloud Hypervisor
fork: https://github.com/cloud-hypervisor/vm-virtio.git

This patch takes care of updating the Cloud Hypervisor code in
virtio-devices and vm-virtio to build correctly with the latest version
of virtio-queue.

Relying on the vm-virtio/virtio-queue crate from rust-vmm which has been
copied inside the Cloud Hypervisor tree, the entire codebase is moved to

The reason for this move is to follow the upstream until we get some
agreement for the patches that we need on top of that to make it
properly work with Cloud Hypervisor.

b5bcdbaf48 misc: Upgrade to use the vm-memory crate w/ dirty-page-tracking
As the first step to complete live-migration with tracking dirty-pages
written by the VMM, this commit patches the dependent vm-memory crate to
the upstream version with the dirty-page-tracking capability. Most
changes are due to the updated `GuestMemoryMmap`, `GuestRegionMmap`, and
`MmapRegion` structs which are taking an additional generic type
parameter to specify what 'bitmap backend' is used.

The above changes should be transparent to the rest of the code base,
e.g. all unit/integration tests should pass without additional changes.

1eb4ebe3d1 vm-virtio: queue: Fix descriptor chain validation
DescriptorChain::is_valid() wrongly used .checked_offset() to attempt to
validate that the descriptor's data is in valid memory. This works in
all cases except where the guest has placed the data at the very end of
the guest memory as the offset + offset will be outside the range (as
the combined offset will be the next byte and as such out of the guest
memory). Instead use the function .check_range() takes an offset and a
length to validate

This fixes issues see with error messages featuring the
DescriptorChainTooShort error.
