this seems the least evil way forward since mono 2.6 and later will see increasing usage, and this only works with what was SQLiteNG
MAC USERS WILL NEED TO CHANGE REFERENCES TO "OpenSim.Data.SQLite.dll" to "OpenSim.Data.SQLiteLegacy.dll" in OpenSim.ini and config-include/StandaloneCommon.ini (if using standalone)
See the OpenSim.ini.example and StandaloneCommon.ini.example files for more details
This commit also temporarily changes unsigned ParentEstateID values in the OpenSim.Data.Tests to signed temporarily, since the new plugin enforces creation of signed fields in the database (which is what the SQL actually specifies). And change data columns in sqlite is a pita.
* Replaced calls to ThreadPool.QueueUserWorkItem() with ThreadPool.UnsafeQueueUserWorkItem() since OpenSim does not use Code Access Security sandboxing
* Added tests for manager, user and group lists.
* Added test for ban list. The test had to be left as ignored as
native MySQL throws exception when ban is saved.
* Added utility class to support parametrized unit tests for range checking.
