I've just pushed out changes implementing a new device API.

This is based on my previous RFC[1], but with a few changes. The main one
being increased used of proxies/wrappers to implement common bus
functionality. For example there are frameworks for PCI, "ISA"[1] and I2C
devices all built on top of a common core.

There's a fair amount still needs to be converted, but I'm reasonably happy
that it is headed in the right direction. Hopefully most of it should be fairly self-explanatory.

Next up is actual config driven machine creation.
