dirstate-v2: Support appending to the same data file...

dirstate-v2: Support appending to the same data file For now we’re still writing the entire data every time, so appending is not useful yet. Later we’ll have new nodes pointing to some existing data for nodes and paths that haven’t changed. The decision whether to append is pseudo-random in order to make tests exercise both code paths. This will be replaced by a heuristic based on the amount of unused existing data. Differential Revision: https://phab.mercurial-scm.org/D11094
