General:
- This documents what I did while on vacation. 
- A fair amount of documentation.
- Implemented Verify Volume to Catalog (needs renaming)
- Modified the database to include new MarkId field as
  well as Counters. Database level is incremented from 1 to  2.
- Added first cut of managing autochangers by implementing Slot in DB.
- Fixed a good number of M_ERROR messages to be M_FATAL where appropriate.
  Also converted a number of Emsg() to Jmsg() permitting better Job error
  messages.
- First cut at implementing a general packet passing mechanism for bsock
  to replace printf and sscanf for passing data.     

Changes submitted this submission:
- Made make_xxx_tables and drop_xxx_tables and create_xxx_database
  for bdb as well as sqlite. With this each database has the
  same set of scripts (with the exception that MySQL has grant_privileges).
- Modified Makefile to only install the database scripts for the
  database that you are using.
- Updated the pdf script to include all the html files.
- Did quite a lot of documentation.
- Made Bacula compile correctly with DEBUG turned off.
- Implemented Pmsg() macros that permit using the debug print
  routines even with DEBUG off.
- Updated job_cancelled() macro to handle JS_FatalError.
- Changed db_find_last_full_verify() to db_find_last_jobid(). This
  permits working with Verify Volume to Catalog.
- Removed TRANSACTION code from incrementing NextId for SQLite. 
- Implemented quick and dirty (not fully functional code) so that
  console program does not die if ctl-Z is entered. 
- Cleaned up backup.c a bit adding a bail_out goto to ensure proper
  handling of errors with minimum code.
- Added passing Slot back and forth to Storage daemon with Volume info.
- Implemented Slot in Media record in DB.
- Implemented first cut of Counter resource in dird_conf.c. A counter
  resource is part of the Pool resource.
- Implemented necessary database record. However, the resource doesn't
  yet create a DB record.
- Implemented onefs (One File System) and recurse options on Include
  resource.
- Implemented autopruning of Verify and Restore Jobs.
- Did a better job of calculating thread_concurrency() for Sun systems.
  This permits better multi-threading allowing all the threads to run
  at the same time.
- Implemented a wait_for_storage_daemon_termination(), which is used by
  backup and verify volume.
- Clarified a number of UA prompts, and add feedback where certain commands
  completed but printed nothing. (More work to be done here).
- Added a pile of new code to implement Verify Volume to Catalog. It is sort
  of a hybrid of "restore" and "verify" in that it actually reads the tape,
  then compares it to the catalog.  Need Verify Volume to Client.
- Added a good number of checks for job_cancelled() this should permit
  quicker and more reliable cancelling of jobs.
- Fixed one bug in restore where I used ofile instead of lname, which means
  that if the lname was too long, the memory was not properly reallocated.
- Cleaned up find_one.c in findlib quite a bit.
- Link smtp static so that it works even if the libraries are messed up.
- If mail host is not found, retry with local host in smtp.
- Added slot and stream to the bootstrap record processing.
- Do offline on tape cartrige for unmount command. This can be turned off
  by the user in the config file. OffLineOnUnmount in Device resource.
- Implemented AutoChanger = yes/no in Device resource.
