WIP: writer: add a signal to notify for errors when writing
Some clients will be interested to know when a write failed for specific reasons, e.g. when there's no space left on the device.
This commit adds a signal to that effect. For now we differentiate between two error codes: a generic one and one for when the writer is out of disk space.
Fixes: #29 (closed)
This is a rebase and re-posting of Cosimo’s patches from #29 (closed) to get more visibility on them.
