This code is ported from the net_util.rs in virtio-devices. The point
being to move it to the net_util crate so that it can later be reused
from vhost-user-net backend.

Yet another small refactoring step for WindowsGuest
after f56471566b.
For this particular case - there's currently neither overloading nor
default argument support in Rust (except a macro or other tricky stuff),
so keep the timeout and other options default for now.

Mark it as unreachable for now in the default implementation as this is
currently only used on tdx code path which is KVM only.

Before this change, the FDT was loaded at the end of RAM. The address of
FDT was not fixed.
While UEFI (edk2 now) requires fixed address to find FDT and RSDP.
Now the FDT is moved to the beginning of RAM, which is a fixed address.
RSDP is wrote to 2 MiB after FDT, also a fixed address.
Kernel comes 2 MiB after RSDP.

These messages are predominantly during the boot process but will also
occur during events such as hotplug.
These cover all the significant steps of the boot and can be helpful for
diagnosing performance and functionality issues during the boot.

This will make `mkfs.ntfs` available in the next image update, so then
it can be used in the tests.

Separate the population of the memory and the HOB from the TDX
initialisation of the memory so that the latter can happen after the CPU
is initialised.

Some refactoring is performed in order to always expect the irqfd to be
provided by VirtioInterrupt trait. In case no irqfd is available, we
simply fail initializing the vhost-user device. This allows for further
simplification since we can assume the interrupt will always be
triggered directly by the vhost-user backend without proxying through
the VMM. This allows for complete removal of the dedicated thread for
both block and net.
vhost-user-fs is a bit more complex as it requires the slave request
protocol feature in order to support DAX. That's why we still need the
VMM to interfere and therefore run a dedicated thread for it.

Now all crates use edition = "2018" then the majority of the "extern
crate" statements can be removed. Only those for importing macros need
to remain.

This will allow progressive porting of parts of the VMM to using
versioned state. A new trait VersionMapped is introduced with a default
implementation that returns an empty VersionMap to ease implementation.
If a struct is updated the the trait will need to be fully implemented
with VersionMapped::version_map() returning a new VersionMap handling
the change.

Bump the sleep time before checking the guest RAM size from 10 to 30
seconds. This will help the VFIO baremetal CI passing more consistently.
