rhg: refactor function to relativize paths in utils Commands like `files`, `status` supports printing relative paths. Hence we need to re-use this code in other places too. So let's take this out from `rhg files` into a utility function. Next patch will make `rhg status` use it. Differential Revision: https://phab.mercurial-scm.org/D11613

hg: let extensions call the func without populating opts keys This change is to help extensions by not forcing them to populate with opts[b'bundle'] and opts[b'force'] when calling hg.incoming(...) Differential Revision: https://phab.mercurial-scm.org/D11619

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
