worker/server: make JobStatus() return JobStatus struct

Browse source 
Personally, I don't like methods returning too much values. I think it's
easy to assign the values in an incorrect order and thus interpreting them
in a wrong way. Also, the following commits will make JobStatus() return
also the JobResult, which would make the number of returned values even
higher.

Not a functional change.
