config: introduce a new value for ui.relative-paths getting old behavior The few places I've modified so far to respect ui.relative-paths have traditionally defaulted showing the path from the repo root. However, some commands (at least `hg files`) default to showing paths relative to the cwd. Let's allow a special value for ui.relative-paths to preserve the old behavior, so we can use that as default value for it. I don't expect that anyone would want to set this value, so perhaps we could have relied on it being unset, but I don't really like behaviors that can only be achieved by a unset config option.

py3: use pycompat.bytestr() on extra values because it can be int One such example is {'close': 1} which marks a branch as closed. This makes test-convert-mtn.t pass on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5864

py3: add some b'' prefixes in hgext/convert/monotone.py # skip-blame because just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D5863

py3: use '%d' for integers instead of '%s' I think this is the last of these occurences because I have got the test passing on python3 in a later patch. Differential Revision: https://phab.mercurial-scm.org/D5862

py3: add 1 new passing test found by buildbot This will make py3 buildbot green again. Differential Revision: https://phab.mercurial-scm.org/D5861

merge: don't unnecessarily calculate absolute path I think this also makes the code clearer (and prepares for a later patch that replaces origpath()). Differential Revision: https://phab.mercurial-scm.org/D5849

largefiles: drop "rel" prefix from filename variables The prefixes were meant to indicate that these paths are repo-relative as opposed to absolute. However, that's what the majority of paths in our code base are, so "rel" made me think they were instead cwd-relative. Let's just drop the prefixes.

branchmap: add some clarifications and clean up flow - Remove indentation where it is not needed. - Swap the subset test branches to follow along logically and put the 'empty' case last. Differential Revision: https://phab.mercurial-scm.org/D5637

branchmap: updating triggers a write Rather than separate updating and writing, create a subclass that doesn't write on update. This minimises chances we forget to write out updates somewhere. This also makes refactoring and improving the branchmap functionality easier. Differential Revision: https://phab.mercurial-scm.org/D5636
