job: Add error message for failing jobs
So far we relied on job->ret and strerror() to produce an error message for failed jobs. Not surprisingly, this tends to result in completely useless messages. This adds a Job.error field that can contain an error string for a failing job, and a parameter to job_completed() that sets the field. As a default, if NULL is passed, we continue to use strerror(job->ret). All existing callers are changed to pass NULL. They can be improved in separate patches.
