This patch fixes two bugs in the job queue scheduling:
 1. It clears the SD status when rescheduling a job so that
    the correct status will be displayed by the Director.
 2. When starting a reschedule thread, it decrements the jcr
    use_count so that the job will not become a zombie.

 Apply it to 1.34.6 (possibly to earlier versions with):

 cd <bacula-source>
 patch -p0 <1.34.6-resched.patch
 make
 ...
