2e5de2f2b3 Reorder the fields in private structures in an effort to reduce alignment 
gaps and thus make the structures smaller, and to put frequently accessed
fields first.  Also update some obsolete comments.  Valgrind shows a very
slight performance improvement.

6fec9ee34c Fix the sqlite3_bind_blob() interface (and its kin) so that the destructor 
is invoked if the binding fails.  Ticket [860399cc408f2dd5f41aed44b]
Update the documentation to explain which interfaces invoke their
destructors on failure and which do not.

5def0843f1 Change the behavior of the sqlite3_wal_hook() callback. It should now return 
SQLITE_OK or an error code and the error code is propagated back up the 
stack.  If a checkpoint is desired, the callback should invoke
sqlite3_wal_callback() itself.
