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
