Log Message:
Update Bacula to the 2.2.2 release.  This includes a major upgrade since
the 2.0.x series.  Major new features include:

- Much faster insertion of attributes (somewhere around 10 times),
  many thanks to Eric Bollengier and Marc Cousin.
- First release of bat (Bacula Administration Tool).  Note to build
  bat you must explicitly enable it on the ./configure line, you
  must have the Qt4 version 4.2 or later libraries loaded, the qwt
  (Qt Graphics) package loaded, and qmake and the other Qt4 tools
  must be available. Most of the implementation was done by Dirk Bartley.
- Red/Black restore in memory tree (500 times faster loading).
- The Regex Where code to allow easier relocation of restored files
  thanks to Eric.
- Socket level heartbeat for all connections (untested).
- posix_fadvise() use in the FD to improve performance reduces
  swapping due to opening/reading lots of files. Win32 equivalent
  implemented.
- Much improved Volume reservation code that should eliminate most
  conflicts experienced in multiple drive autochangers.
- Simpler locking in the SD in the reservation system.
- Detection of file size/date change during backup if enabled.
- New Recycle Pool feature -- thanks to Eric.
- Efficient implementation of very large include/exclude lists.
- Volumes are no longer pruned during 'status dir'
- Pruning is now more efficient, and if a Volume is purged,
  during pruning, it is immediately discovered.
- License is now GPL v2 without modifications, fix a few copyright
  mistakes made when adding FSFE copyright notice.

Important upgrade notes are mentioned in the MESSAGE file.

XXX Not (functionally) tested by myself, but Peter Eisch <peter@boku.net>
    (via pkgsrc-users@NetBSD.org) verified the patch in his setup.
