Could you clarify what this patch is used for please. I'll add some 
context. Berkeley DB SQL does not use the SQLite VFS code - it is one of 
the components that has been replaced.

So, if those functions need to be exposed so that you can modify the 
behavior of SQLite (by implementing a custom VFS), then your changes 
should no longer be necessary.

Thanks,
Alex
