0249e8641a Move Cloud Hypervisor to virtio-queue crate 
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 new definition of a Queue and other related structures.

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.

7f0e7d19a6 Revert "build: bump vm-memory from 0.6.0 to 0.7.0" 
This was causing some issues because of the use of 2 different versions
for the vm-memmory crate. We'll wait for all dependencies to be properly
resolved before we move to 0.7.0.

This reverts commit 76b6c62d07.

This needed a bunch of manual updates as well, including vfio-ioctls and
vhost crates. The vhost crate is being patched with the latest version
from rust-vmm because the version 0.1.0 on crates.io doesn't include the
patches we need yet.

b2cc45e0a3 vhost_user_*: set up logging 
These crates are written to produce log messages using the error!
macro, but their logs didn't actually go anywhere, which made it very
difficult to debug when they're not working.

I've used env_logger here because it's the same log implementation
that the hypervisor crate uses.

deb4ad5e23 vhost_user_*: mark --*-backend as required 
I don't think the min_values(1) was doing anything, since
takes_value(true) was already set, and after this change I still get
an error if I try to supply the argument with no value.

But the unwrap below would fail if the argument wasn't supplied at
all.  By setting required(true) we get a nice message from clap
instead.

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.

ffaab46934 misc: Use a more relaxed memory model when possible 
When a total ordering between multiple atomic variables is not required
then use Ordering::Acquire with atomic loads and Ordering::Release with
atomic stores.

This will improve performance as this does not require a memory fence
on x86_64 which Ordering::SeqCst will use.

Add a comment to the code in the vCPU handling code where it operates on
multiple atomics to explain why Ordering::SeqCst is required.
