rust-dirstate: merge `dirstate_tree` module into `dirstate` The historical reasonning for `dirstate_tree` existing in the first place is that a new approach was needed for the tree-like dirstate and it was easier to start somewhat fresh. Now that the former dirstate is (long) gone, we can merge those two modules to avoid the confusion that even the module creators sometimes get.
