By using `net_util::open_tap` to create the TAP interface, the created
interface will be deleted when the returned variable (`net_utils::Tap`)
is dropped.

This patch enables multi-queue support for creating virtio-net devices by
accepting multiple TAP fds, e.g. '--net fds=3:7'.

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.

Because of the behavior of the NVIDIA proprietary driver, we can't
expect NVIDIA cards with only MSI support to be functioning correctly
after they've been passed through with Cloud-Hypervisor.

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.

Since QCOW and RAW synchronous implementation are very close, it makes
sense to introduce some common functions that can be shared between
these two.

Now that BlockIoUring is the only implementation of virtio-block,
handling both synchronous and asynchronous backends based on the
AsyncIo trait, we can rename it to Block.

Now that both synchronous and asynchronous backends rely on the

Based on the synchronous QCOW file implementation present in the qcow
crate, we created a new qcow_sync module in block_util that ports this
synchronous implementation to the AsyncIo trait.
The point is to reuse virtio-blk asynchronous implementation for both
synchronous and asynchronous backends.

Based on the new DiskFile and AsyncIo traits, the implementation of
asynchronous block support does not have to be tied to io_uring anymore.
Instead, the only thing the virtio-blk implementation knows is that it
is using an asynchronous implementation of the underlying disk file.
