f4495de143 vmm: Improve handling of shared memory backing
As huge pages are always MAP_SHARED then where the shared memory would
be checked (for vhost-user and local migration) we can also check
instead for huge pages.

The checking is also extended to cover the memory zones based
configuration as well.

99d9a3d299 vmm: memory_manager: Avoid MAP_PRIVATE CoW with VFIO for hugepages too
We can't use MAP_ANONYMOUS and still have huge pages so MAP_SHARED is
effectively required when using huge pages.

Unfortunately it is not as simple as always forcing MAP_SHARED if
hugepages is on as this might be inappropriate in the backing file case
hence why there is additional complexity of assigning to mmap_flags on
each case and the MAP_SHARED is only turned on for the anonymous file
huge page case as well as anonymous shared file case.

1f0e5eb66a vmm: virtio-devices: Restore every VirtioDevice upon creation
Following the new design proposal to improve the restore codepath when
migrating a VM, all virtio devices are supplied with an optional state
they can use to restore from. The restore() implementation every device
was providing has been removed in order to prevent from going through
the restoration twice.

Here is the list of devices now following the new restore design:

- Block (virtio-block)
- Net (virtio-net)
- Rng (virtio-rng)
- Fs (vhost-user-fs)
- Blk (vhost-user-block)
- Net (vhost-user-net)
- Pmem (virtio-pmem)
- Vsock (virtio-vsock)
- Mem (virtio-mem)
- Balloon (virtio-balloon)
- Watchdog (virtio-watchdog)

- Console (virtio-console)
- Iommu (virtio-iommu)

b4e3942708 api: Fix vm.add-device argument type
The add_device() function, from the device manager code, takes a
DeviceConfig as a parameter, instead of a VmAddDevice.

The change was originally done as part of 34412c9b41 and it didn't
break Kata Containers because the VmAddDevice and DeviceConfig structs
share most of their fields, besides the optional for serialization
`pci_segment`, which is not used by the client yet.

c52ccf3992 vmm: migration: Create destination VM right before to restore it
This is preliminary work to ensure a migrated VM is created right before
it is restored. This will be useful when moving to a design where the VM
is both created and restored simultaneously from the Snapshot.

In details, that means the MemoryManager is the object that must be
created upon receiving the config from the source VM, so that memory
content can be later received and filled into the GuestMemory.
Only after these steps happened, the snapshot is received from the
source VM, and the actual Vm object can be created from both the
snapshot and the MemoryManager previously created.

099cdd2af8 virtio-devices, vmm: vdpa: Implement live migration support
Vdpa now implements the Migratable trait, which allows the device to be
added to the DeviceTree and therefore allows live migrating any vDPA
device that supports being suspended.

Given a vDPA device can't be resumed from a suspended state without
having to reset everything, we don't support pause/resume for a vDPA
device, as well as snapshot/restore (which requires resume to be
supported).

In order for the migration to work locally, reusing the same device on
the same host machine, the vhost-vdpa handler is dropped after the
snapshot has been performed, which allows the destination VM to open the
device without any conflict about the device being busy.
