+ - odb: store ODB source in `struct odb_transaction`
+
+ Transaction to create objects (or not) is currently tied to the
+ repository, but in the future a repository can have multiple object
+ sources, which may have different transaction mechanisms.  Make the
+ odb transaction API per object source.
