rhg: fallback if tweakdefaults or statuscopies is enabled with status `rhg status` is experimental right now and does not support all functionalities. While the long term target is to implement them, for now we add a fallback to have all tests pass with `rhg status` enabled. Differential Revision: https://phab.mercurial-scm.org/D10906

largefiles: partially undo 61e526585b20e2ff15f19497d0451d18fea02db8 and child Since the largefiles dirstate is now part of transaction, we get rid of this temporary fix which lived for ~7 years. Differential Revision: https://phab.mercurial-scm.org/D11612

largefiles: add tr backup for largefilesdirstate This will help us in automatically restoring the largefilesdirstate if a transaction is rolled back. Differential Revision: https://phab.mercurial-scm.org/D11611

largefiles: pass current transaction to `lfdirstate.write()` Right now, the largefile dirstate is not included in transaction which makes things complex. Next patch will add code to do so, so let's make it mandatory to pass current transaction and pass from all existing callers. Differential Revision: https://phab.mercurial-scm.org/D11610

dirstate-v2: Move data file info in the docket closer together Having `data_size` next to `uuid_size` (and the UUID itself) makes more sense. Differential Revision: https://phab.mercurial-scm.org/D11545
