By introducing a ResizeSender object, we avoid having a Resize clone
with a different content than the original Resize object.

MOV R/RM is a special case of MOVZX, so we generalize the mov_r_rm macro
to make it support both instructions.

The vhd module is the implementation of the VHD specification, which is
why it is important to unit test it.

Let's create a fixed VHD disk file from the existing RAW file thanks to
qemu-img, and create a new integration test to validate that
Cloud-Hypervisor can boot VHD disk image.

Relying on the simplified version of the synchronous support for RAW
disk files, the new fixed_vhd_sync module in the block_util crate
introduces the synchronous support for fixed VHD disk files.
With this patch, the fixed VHD support is complete as it is implemented
in both synchronous and asynchronous versions.

Using directly preadv and pwritev, we can simply use a RawFd instead of
a file, and we don't need to use the more complex implementation from
the qcow crate.

This commit adds the asynchronous support for fixed VHD disk files.
It introduces FixedVhd as a new ImageType, moving the image type
detection to the block_util crate (instead of qcow crate).
It creates a new vhd module in the block_util crate in order to handle
VHD footer, following the VHD specification.
It creates a new fixed_vhd_async module in the block_util crate to
implement the asynchronous version of fixed VHD disk file. It relies on
io_uring.

This helper can open a TAP device and configure the interface on it. If
the device needs to be opened multiple times for MQ then it also handles
that correctly.

The unit tests ask the Linux kernel to generate a TAP device name on
demand by passing in a format string. I suspect, but haven't been able
to confirm that there might be a rare race that triggers when creating
lots of devices in a short period of time. This is appearing in our unit
test as the occassional flake of the test_tap_read() which although it
has successfully created the device it fails to set the IP address on it
when looking it back up by it's name.
Since this is the most frequent cause of failures on our CI use a lock
to ensure that multiple TAP devices are not created simultaneously.

This skeleton commit brings in the support for compiling aarch64 with
the "acpi" feature ready to the ACPI enabling. It builds on the work to
move the ACPI hotplug devices from I/O ports to MMIO and conditionalises
any code that is x86_64 only (i.e. because it uses an I/O port.)
Filling in the aarch64 specific details in tables such as the MADT it
out of the scope.
