a8839c4a4e tests: Disable live_upgrade test on AArch64
The `live_upgrade` test was broken when the Gic snapshot moved from `Vm`
to `DeviceManager`.

b173f6f654 vmm,devices: Change Gic snapshot and restore path
The snapshot and restore of AArch64 Gic was done in Vm. Now it is moved
to DeviceManager.

The benefit is that the restore can be done while the Gic is created in
DeviceManager.

While the moving of state data from Vm snapshot to DeviceManager
snapshot breaks the compatability of migration from older versions.

b62a40efae virtio-devices, vmm: Always restore virtio devices in paused state
Following the new restore design, it is not appropriate to set every
virtio device threads into a paused state after they've been started.

This is why we remove the line of code pausing the devices only after
they've been restored, and replace it with a small patch in every virtio
device implementation. When a virtio device is created as part of a
restored VM, the associated "paused" boolean is set to true. This
ensures the corresponding thread will be directly parked when being
started, avoiding the thread to be in a different state than the one it
was on the source VM during the snapshot.

e2e02c8f69 fuzz: Add fuzzer for virtio-net
To synthesize the interactions between the virtio-net device and the tap
interface, the fuzzer utilizes a pair of unix domain sockets: one socket
(e.g. the dummy tap frontend) is used to construct the 'net_util::Tap'
instance for creating a virtio-net device; the other socket (e.g. the
dummy tap backend) is used in a epoll loop for handling the tx and rx
requests from the virtio-net device.

83ab5ea528 virtio-devices: net: Provide custom functions for fuzzing
Three functions are added:
* 'Tap::new_for_fuzzing()' a custom constructor that creates a dummy
`Tap` interface directly from `File` backed by Unix domain socket;
* 'Tap::mtu()' a custom function that returns hard-coded mtu;
* 'Net::wait_for_epoll_threads()'.

Two functions are reused with modifications to work with the dummy 'Tap'
interface:
* 'Net::new_with_tap()' is made public for fuzzing;
* 'Net::activate()' is modified to not call into 'Tap::set_offload()'
for fuzzing.

as preliminary work for creating the vCPUs before the DeviceManager,
which is required to ensure both x86_64 and aarch64 follow the same

It's important to note the optimization for faster PIO accesses on the
PCI config space had to be removed given the VmOps was required by the
CpuManager and by the Vcpu by extension. But given the PciConfigIo is
created as part of the DeviceManager, there was no proper way of moving
things around so that we could provide PciConfigIo early enough.
