vfio: VFIO API wrappers and helpers The Virtual Function I/O (VFIO) kernel subsystem exposes a vast and relatively complex userspace API. This commit abstracts and simplifies this API into both an internal and external API. The external API is to be consumed by VFIO device implementation through the VfioDevice structure. A VfioDevice instance can: - Enable and disable all interrupts (INTX, MSI and MSI-X) on the underlying VFIO device. - Read and write all of the VFIO device memory regions. - Set the system's IOMMU tables for the underlying device.

vm-virtio, vmm, vfio: Store GuestMemoryMmap in an Arc<ArcSwap<T>> This allows us to change the memory map that is being used by the devices via an atomic swap (by replacing the map with another one). The ArcSwap provides the mechanism for atomically swapping from to another whilst still giving good read performace. It is inside an Arc so that we can use a single ArcSwap for all users. Not covered by this change is replacing the GuestMemoryMmap itself. This change also removes some vertical whitespace from use blocks in the files that this commit also changed. Vertical whitespace was being used inconsistently and broke rustfmt's behaviour of ordering the imports as it would only do it within the block.

vfio: Initial PCI support This brings the initial PCI support to the VFIO crate. The VfioPciDevice is the main structure and holds an inner VfioDevice. VfioPciDevice implements the PCI trait, leaving the IRQ assignments empty as this will be driven by both the guest and the VFIO PCI device, not by the VMM. As we must trap BAR programming from the guest (We don't want to program the actual device with guest addresses), we use our local PCI configuration cache to read and write BARs.

cargo: Bump the kvm and vmm-sys-util crates Since the kvm crates now depend on vmm-sys-util, the bump must be atomic. The kvm-bindings and ioctls 0.2.0 and 0.4.0 crates come with a few API changes, one of them being the use of a kvm_ioctls specific error type. Porting our code to that type makes for a fairly large diff stat. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
