Refresh the object database to load newly added files.
If the object databases have changed on disk while the library
is running, this function will force a reload of the underlying
indexes.
Use this function when you're confident that an external
application has tampered with the ODB.
NOTE that it is not necessary to call this function at all. The
library will automatically attempt to refresh the ODB
when a lookup fails, to see if the looked up object exists
on disk but hasn't been loaded yet.
@param db database to refresh
@return 0 on success, error code otherwise
