Assigned to myself because #47 (which this is based on) still needs some work on my side. |

The operating system call to set the GPIO output state may fail. Make sure that this results in an orderly teardown of the tacd instead of a panic. This also necessitates a change to the test and demo_mode gpio stubs, so they can be `?`-operatored into anyhow Results (simply by making them anyhow results).

Since we can now return early from `wtb.spawn_thread`-spawned threads, because they handle error propagation out of the thread context for us we no longer have to use queues to send back error results manually. Use that to simplify error handling in the thread setup and the steady state. Signed-off-by: Leonard Göhrs <l.goehrs@pengutronix.de>
Now that errors from threads are properly propagated we can simplify the error handling and do not have to transfer `Result`s across queues if something goes wrong during thread setup. Signed-off-by: Leonard Göhrs <l.goehrs@pengutronix.de>

This PR adds some of the improved error handling that is hinted at in #47. For now that means:
