1b1a2175ca vm-migration: Define the Snapshottable and Transportable traits 
A Snapshottable component can snapshot itself and
provide a MigrationSnapshot payload as a result.

A MigrationSnapshot payload is a map of component IDs to a list of
migration sections (MigrationSection). As component can be made of
several Migratable sub-components (e.g. the DeviceManager and its
device objects), a migration snapshot can be made of multiple snapshot
itself.
A snapshot is a list of migration sections, each section being a
component state snapshot. Having multiple sections allows for easier and
backward compatible migration payload extensions.

Once created, a migratable component snapshot may be transported and this
is what the Transportable trait defines, through 2 methods: send and recv.

Both clock_gettime and gettimeofday syscalls where missing when running
Cloud-Hypervisor on a Linux host without vDSO enabled. On a system with
vDSO enabled, the syscalls performed by vDSO were not filtered, that's

cc67131ecc vmm: Retrieve new memory region when memory is extended 
Whenever the memory is resized, it's important to retrieve the new
region to pass it down to the device manager, this way it can decide
what to do with it.

Also, there's no need to use a boolean as we can instead use an Option
to carry the information about the region. In case of virtio-mem, there
will be no region since the whole memory has been reserved up front by
the VMM at boot. This means only the ACPI hotplug will return a region
and is the only method that requires the memory to be updated from the
device manager.
