76087f1235 script: cargo: Improve the cargo tests
We don't need to force the cargo-audit install, we can check if it's
already available instead and install if it's not.

Also, since we now have workspaces properly setup, we can call directly
into cargo fmt and avoid calling into find magic incantation.

db6f894e5e scripts: Add container based development script
The script is a development tool that runs all commands in a dedicated
container. This allows for containerized, isolated and reproducible
builds and CI runs.

The script supports the following command:

* build: Build Cloud Hypervisor binaries (debug and release)
* build-container: Build the container used by the script
* tests: Run unit, cargo and integration tests

$ ./scripts/dev_cli.sh help

Cloud Hypervisor dev_cli.sh
Usage: dev_cli.sh <command> [<command args>]

Available commands:

    build [--debug|--release] [-- [<cargo args>]]
        Build the Cloud Hypervisor binaries.
        --debug               Build the debug binaries. This is the default.
        --release             Build the release binaries.

    tests [--unit|--cargo|--all]
        Run the Cloud Hypervisor tests.
        --unit               Run the unit tests.
        --cargo              Run the cargo tests.
	--integration        Run the integration tests.
        --all                Run all tests.

    build-container [--type]
        Build the Cloud Hypervisor container.
        --dev                Build dev container. This is the default.

bac0d1e689 iommu: Implement virtio topology configuration
Based on the new structures previously introduced, the new topology
feature is being fully implemented through this commit. This allows
the description of the devices attached to the virtual IOMMU, which
is why a new function attach_devices() has been introduced. It gives
the virtual IOMMU device the full list of devices which must be attached
to it, letting the device share this information through its virtio
configuration.

0c73ff8129 iommu: Add topology structures
The virtio-iommu device defines a new virtio feature allowing the
topology to be discovered fully through virtio configuration.

By topology, it means describing the devices attached to the virtual
IOMMU. This is currently managed through ACPI with IORT and VIOT table,
but this is another way of describing it.

db42caef42 vm-virtio: Handle special virtio-pci capability CAP_PCI_CFG
The virtio capability VIRTIO_PCI_CAP_PCI_CFG is exposed through the
device's PCI config space the same way other virtio-pci capabilities
are exposed.

The main and important difference is that this specific capability is
designed as a way for the guest to access virtio capabilities without
mapping the PCI BAR. This is very rarely used, but it can be useful when
it is too early for the guest to be able to map the BARs.

One thing to note, this special feature MUST be implemented, based on
the virtio specification.

db9f9b7820 pci: Make self mutable when reading from PCI config space
In order to anticipate the need to support more features related to the
access of a device's PCI config space, this commits changes the self
reference in the function read_config_register() to be mutable.

This also brings some more flexibility for any implementation of the
PciDevice trait.
