Registers a IUnlockNotifyHandler used to handle database locks.
When running in shared-cache mode, a database operation may fail with an SQLITE_LOCKED error if
the required locks on the shared-cache or individual tables within the shared-cache cannot be obtained.
See SQLite Shared-Cache Mode for a description of shared-cache locking.
This API may be used to register a callback that SQLite will invoke when the connection currently
holding the required lock relinquishes it.
This API can be used only if the SQLite library was compiled with the SQLITE_ENABLE_UNLOCK_NOTIFY
C-preprocessor symbol defined.
