[PATCH 3/5] API: Add VIR_DOMAIN_JOB_ERRMSG domain job statistics field
In some cases it's useful to report the error which caused the domain
job to fail. Add an optional field for holding the error message so that
it can be later retrieved from statistics of a completed job.
Add the field name macro and code for extracting it in virsh.
