The code already don't freeze base node and we try to make it prepared for the situation when base node is changed during the operation. In other words, block-stream doesn't own base node. Let's introduce a new interface which should replace the current one, which will in better relations with the code. Specifying bottom node instead of base, and requiring it to be non-filter gives us the following benefits: - drop difference between above_base and base_overlay, which will be renamed to just bottom, when old interface dropped - clean way to work with parallel streams/commits on the same backing chain, which otherwise become a problem when we introduce a filter for stream job - cleaner interface. Nobody will surprised the fact that base node may disappear during block-stream, when there is no word about "base" in the interface.
