- Correct buffer length passed to inet_ntop() in address_conf.c

- Increase the debug level of a lot of messages to reduce the
  debugging noise.
- Modify how ST_APPEND is handled so that nothing is written
  to the Volume if it is not set. It is now set only when
  the Volume label is verified, and released when the volume
  is released. This required a number of minor but rather
  critical and fundamental changes.
- Improve quickly terminating a job in the SD when it errs.
  More status checking and a few additional checks on
  job_canceled() and check more error return statuses.
- Added a number of debug statements (to be removed later) that
  check the VolCatName for a name.
- Create a single subroutine that handles terminating writing
  on a Volume at the end of the volume (or after an error).
- Continued to add use of the berrno classs for strerror().
