Log Message:
Rework the changer driver a bit:
- Take note of magazine changes, and enqueue "Element Status Changed" events
  that user processes can read or select on.
- Normalize some structure names.
- Report back more status about changer elements:
  * Volume tags (e.g. barcode labels on the backs of your tapes)
  * External device names (for drive units in a changer)
  * Last element a unit of media was moved from
  * Sense information for SCSI changer elements in EXCEPT condition
  * Vendor-specific data if the user requests it.
- Add support for setting volume tags.
