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.

92d7652379 When the in single-threaded mode, the sqlite3_mutex_alloc() interface 
still returns a non-NULL value.  The mutex doesn't do anything, but it
tests non-NULL.  This way, extensions (or VFSes) that use sqlite3_mutex_alloc()
can tell the difference between an OOM error and mutexes being disabled.
