Attaching the patch file with the changes to use threadsafeCopy() API

[Srikumar B]

tracker database path(m_databaseDirectoryPath) is being used in multiple places. 

trackerDatabasePath() and deleteOrigin() APIs currently use the DB path without using threadsafeCopy() but these APIs can be called from multiple threads as this tracker DB path is common for all threads which use Database

when the databaseGuard lock hasn't been taken

> +    return SQLiteFileSystem::appendDatabaseFileNameToPath(m_databaseDirectoryPath.threadsafeCopy(), "Databases.db");

This one seems good.

> Source/WebCore/storage/DatabaseTracker.cpp:820
> +           SQLiteFileSystem::deleteEmptyDatabaseDirectory(m_databaseDirectoryPath.threadsafeCopy());

This seems unnecessary since the lock m_databaseGuard has been taken.
