Rename the I/O accessors provided by `Io` to encode the type as
number instead of letter. This is in preparation for Port I/O support
to use a trait for generic accessors.
Add a `c_fn` argument to the accessor generation macro to translate
between rust and C names.

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.
