ac950d9a97 build: Bulk update dependencies
Update all dependencies with "cargo upgrade" with the exception of
vmm-sys-utils which needs some extra porting work.

db5b4763c2 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.

2cec3aad7f 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.
