Add SQLiteSourceId property to the SQLiteConnection class to return the SQLite core library source identifier. Enhance and revising Trace output (in DEBUG only) to be more accurate and to report resource cleanup exceptions. More work on unit testing infrastructure and the test case for ticket [e30b820248]. The SQLite3 class should always attempt to dispose the contained SQLiteConnectionHandle, even when called via the finalizer. check-in: 1808779aa2 user: mistachkin tags: tkt-e30b820248
