Finishing implementation of sql-backend for datebook. But I have to

port the PIM datebook application to use it, before I could debug the
whole stuff.
Thus, PIM-Database backend is finished, but highly experimental. And some
parts are still generic. For instance, the "queryByExample()" methods are
not (or not fully) implemented. Todo: custom-entries not stored.
The big show stopper: matchRegExp() (needed by OpieSearch) needs regular
expression search in the database, which is not supported by sqlite !
Therefore we need either an extended sqlite or a workaround which would
be very slow and memory consuming..

  * Revision 1.8  2003/09/22 14:31:16  eilers
  * Added first experimental incarnation of sql-backend for addressbook.
  * Some modifications to be able to compile the todo sql-backend.
  * A lot of changes fill follow...
  *
  * Revision 1.7  2003/08/01 12:30:16  eilers
  * Merging changes from BRANCH_1_0 to HEAD
  *
  * Revision 1.6.4.1  2003/06/30 14:34:19  eilers
  * Patches from Zecke:
  * Fixing and cleaning up extraMap handling
  * Adding d_ptr for binary compatibility in the future
  *
  * Revision 1.6  2003/04/13 18:07:10  zecke
  * More API doc
  * QString -> const QString&
  * QString = 0l -> QString::null
  *
  * Revision 1.5  2003/02/21 23:31:52  zecke
  * Add XML datebookresource
  * -clean up todoaccessxml header
  * -implement some more stuff in the oeven tester
  * -extend DefaultFactory to not crash and to use datebook
  *
  * -reading of OEvents is working nicely.. saving will be added
  *  tomorrow
  *  -fix spelling in ODateBookAcces
  *
  * Revision 1.4  2002/10/14 15:55:18  eilers
  * Redeactivate SQL.. ;)
  *
  * Revision 1.3  2002/10/10 17:08:58  zecke
  * The Cache is finally in place
  * I tested it with my todolist and it 'works' for 10.000 todos the hits are awesome ;)
  * The read ahead functionality does not make sense for XMLs backends because most of the stuff is already in memory. While using readahead on SQL makes things a lot faster....
  * I still have to fully implement read ahead
  * This change is bic but sc
  *
  * Revision 1.2  2002/10/08 09:27:36  eilers
  * Fixed libopie.pro to include the new pim-API.
  * The SQL-Stuff is currently deactivated. Otherwise everyone who wants to
  * compile itself would need to install libsqlite, libopiesql...
  * Therefore, the backend currently uses XML only..
  *
  * Revision 1.1  2002/10/07 17:35:01  eilers
  * added OBackendFactory for advanced backend access
  *
