This is the second iteration of the Theobroma Systems CAN/USB
adapter driver.

Thanks to feedback from the list and additonal internal stress-testing,
the driver, the wire protocol and the device firmware have been improved.

Among other changes, error states are now handled, and an explicit
tx completion message has been added.

A few questions and review comments are still open. I will post an
email gathering all answers in a reply to this cover letter.
