- Note. Your database must be updated, or you must create
  a new database. I have not yet incremented the database level.
- Add Location table.
- Add LocationId, DeviceId, and MediaTypeId to Media record.

- Implement create/get mac record in database for adding extended
  Migration data to the job record.
- Add new MAC table to update/make database scripts.
- Return Storage name used when getting VolumeNames for a job.
- Change bsr file keyword Storage to Device, which is more accurate.
- Ensure that Mac records are pruned/purged.
- Tweak SD tools to deal with changing media type.
- Integrate more dev.c subroutines as methods (e.g. strerror, bsr, ...)
- Pass pointer to dcr pointer to acquire_device_for_read() so
  that the subroutine can switch devices, and hence dcrs.
- Modify the multiple MediaType read code to re-use the same
  dcr when switching devices. This makes the code much more
  robust.
- Integrate patch from Karl Hakimian that reads JobIds, FileIndexes
  from a table for restore.
- Add Storage name to VolParams, but it really should be Device.
