Make the code a bit clearer by changing the naming of the structure
holding the list of IRQs reserved for PCI devices. It is also modified
into an array of 32 entries since we know this is the amount of PCI
slots that is supported.

We define a new enum in order to classify PCI device under virtio or
VFIO. This is a cleaner approach than using the Any trait, and
downcasting it to find the object back.

Introduces a tuple holding both information needed by pci_id_list and
pci_devices.
Changes pci_devices to be a BTreeMap of this new tuple.
Now that pci_devices holds the information needed from pci_id_list,
pci_id_list is no longer needed.

In anticipation for further factorization, the pci_id_list is now a
hashmap of PCI b/d/f leading to each device name.

Instead of relying on a PCI specific device list, we use the DeviceTree
as a reference to determine if a device name is already in use or not.

Remove the startup message containing incomplete VM configuration
details. It's a bit unusual for a tool such as Cloud Hypervisor to print
those kind of details which are a direct representation of the command
line.

This includes:
* OS disk image management
* Cloud init creation
* SSH to guest access
* Waiting for guest to boot
This will be useful in other projects that want to do similar things in
their integration tests.

Only if we have a valid API server path then create the API server. For
now this has no functional change there is a default API server path in
the clap handling but rather prepares to do so optionally.

In case of the virtio frontend driver doesn't need interupts for
certain queue event, it may explicitly write VIRTIO_MSI_NO_VECTOR
to the virtio common configuration, or it may doesn't configure
the event type vector at all.
This patch initializes both MSI-X configuration vector and queue vector
with VIRTIO_MSI_NO_VECTOR, so that the backend drivers won't trigger
unexpected interrupts to the guest.

Relying on a NVIDIA Tesla T4 card present in the SGX machine, this patch
enables baremetal VFIO testing, validated by running several NVIDIA
tools in the guest. The guest image has been prepared to include all the
software needed to run these tests.

Enabled all "ttyS0" related test cases:

On AArch64, interrupt controller (GIC) is emulated by KVM. VMM need to
set IRQ routing for devices, including legacy ones.
Before this commit, IRQ routing was only set for MSI. Legacy routing
entries of type KVM_IRQ_ROUTING_IRQCHIP were missing. That is way legacy
devices (like serial device ttyS0) does not work.
The setting of X86 IRQ routing entries are not impacted.

Now that virtio devices can be updated with add_memory_region(), there's

Relies on the preliminary work allowing virtio devices to be updated
with a single memory at a time instead of updating the entire memory at
once.

Assuming vhost-user devices support CONFIGURE_MEM_SLOTS protocol
feature, we introduce a new method to the VirtioDevice trait in order to
update one single memory at a time.
In case CONFIGURE_MEM_SLOTS is not supported by the backend (feature not
acked), we fallback onto the current way of updating the memory
mappings, that is with SET_MEM_TABLE.
