This commit adds a sample Rust PCI driver for QEMU's "pci-testdev"
device. To enable this device QEMU has to be called with
`-device pci-testdev`.
The same driver shows how to use the PCI device / driver abstractions,
as well as how to request and map PCI BARs, including a short sequence of
MMIO operations.

This sample driver demonstrates the following basic operations:
* Register a Misc Device
* Create /dev/rust-misc-device
* Provide open call-back for the aforementioned character device
* Operate on the character device via a simple ioctl()
* Provide close call-back for the character device

The beginning of a set of Rust modules that showcase how Rust
modules look like and how to use the abstracted kernel features.
It also includes an example of a Rust host program with
several modules.
These samples also double as tests in the CI.
