bookmarks: move the `mirror` option to the `paths` section A new `bookmarks` section with a `mirror` option have been added. That option has never been released yet. This new options is limited since it affect all paths without distinction. In case where a repository is interacting with multiple peers, being able to control behavior on a path basis can be quite valuable. In addition, having more variant of behavior would be interesting, especially a mode where no bookmark exchanged is tried at all. Such new mode (implemented later) make a lot of sense for configuration on a path-basis. Configuration of the default behavior is still possible through the usage of generic path configuration. The "old" config, becomes: [bookmarks] mirror=True becomes: [path] *:bookmarks.mode=mirror Differential Revision: https://phab.mercurial-scm.org/D11675

path: keep the path instance in the `pulloperation` This will allow more pull code to use the path options. Ideally we would modify the peer API to keep the path instance. However that is much more churn that I can deal with for my current goal: adjusting a user facing API for a new feature before we release it in the 6.0 changesets. So I am taking a shortcut that seems reasonable. Differential Revision: https://phab.mercurial-scm.org/D11674

path: return path instance directly from get_pull_paths This means the caller has to do a bit more work, however it give access to the `path` instance and the information it contains. Differential Revision: https://phab.mercurial-scm.org/D11673

path: unify path creation in `get_pull_paths` This remove a special case and will make it possible to return `path` instance directly. Differential Revision: https://phab.mercurial-scm.org/D11672

path: add a new argument to control path validation During pull, unvalidated path might be used, having the option to do so directly will allow use to simplify some code and unlock more `path` usage later in the series. Differential Revision: https://phab.mercurial-scm.org/D11671

rhg: internally, return a structured representation from hg cat The purpose of this change is to make it possible to support limited templating in `hg cat`, so we could print separators between files etc. The templating itself is not implemented yet, so this functionality is unused in `rhg cat`. However, in our fork of hg we're implementing a slightly different command `hg jscat` which makes use of this. So accepting this change will let us minimize the size of the patch we're maintaining on our side. Differential Revision: https://phab.mercurial-scm.org/D11679

dirstate-v2: add an option to prevent unintentional slow dirstate-v2 This is the project policy discussed in November 2020 and already put to use for the persistent nodemap. Differential Revision: https://phab.mercurial-scm.org/D11668

chistedit: add option to show order of commits in opposite order Many users (including me) expect the order of commits in histedit to match the order in `hg log -G` and are confused because it doesnn't. This patch adds an option to show later commits first in the list. I've only added support for it in chistedit for now. As a consequence, I've marked the config option experimental (I think it should apply to both interfaces before it graduates). Differential Revision: https://phab.mercurial-scm.org/D11669
