These tests use relatively large memory allocations and if they are
allowed to run in parallel can result in the container encountering an
OOM situation.

Update the vhost-user-backend crate version used along with related
crates (vhost and virtio-queue.) This requires minor changes to the
types used for the memory in the backends with the use of the
BitmapMmapRegion type for the Bitmap implementation.

Replace the specific Bitmap implementation from the type signature used
for functions that take memory. This allows more flexibility when using
these functions in particular when these functions are used by the
vhost-user-block backend. An updated vhost-user-backend crate requires
extra constraints on the Bitmap implementation used (it must support
BitmapReplace which AtomicBitmap does not.)

This is to resolve the inconsistencies from our openapi specification,
as default values do not make sense for required fields.

Change from default 4G to 2G to reduce the memory usage. This will help
avoid "No disk space left" errors when all snapshot tests run at once.

The snapshot_dir is not needed anymore fter the guest is restored.
Hence, remove it. This will potentially avoid transient failures caused
due to insufficient disk space.

The mem_size field is not needed in TestContext. Drop it.
Make sure guest_evvq is read once. Clippy cannot figured out that it was
used.
While at it, add an extra assert for the spurious rxvq event test, too.

Clippy complained one use of the char_array macro.
Instead of fixing that use case, the observation is that the macro was
needed only because MP table types mixed c_char and c_uchar for no
particular reason.
Only use c_uchar in those types, and drop char_array.

As MSHV also implements set/get_clock data, this patch
removes the KVM feature guard and make it x86_64 only and
both for KVM and MSHV.

The contents of this crate may change and cause conflicts - re-exporting
the contents is unnecessary.

This is required as the VcpuFd::run and VcpuFd::set_immediate_exit
methods now take a &mut self. I explored alternative solutions:
1. Using RefCell for runtime interior mutability - the Vcpu trait is
Sync and it's not possible to use RefCell with types that are Sync.
2. Using UnsafeCell - the mutable reference nature of ::run and and
::set_kvm_immediate_exit was added for a reason so it unwise to
bypass this.
3. Adjusting the trait interface to expose the &mut self - this requires
an Arc<Mutex<>> around the hypervisor::vcpu::Vcpu object and was very
intrusive.

The members for {Io, Mmio}{Read, Write} are unused as instead exits of
those types are handled through the VmOps interface. Removing these is
also a prerequisite due to changes in the mutability of the
VcpuFd::run() method.

On Microsoft Hypervisor, we need to save/restore five
VP state components which are as follows:
1. Local APIC
2. Xsave
3. Synthetic Message Page
4. Synthetic Event Flags Page
5. Synthetic Timers
In the MSHV crate we created a single struct for all the
components and API to get/set the states.

When using multiple PCI segments, the 32-bit and 64-bit mmio
aperture is split equally between each segment. Add an option
to configure the 'weight'. For example, a PCI segment with a
`mmio32_aperture_weight` of 2 will be allocated twice as much
32-bit mmio space as a normal PCI segment.
