linkrev: fix issue with annotate of working copy The introrev was appearing as None in new annotate tests, which the code from the stable branch wasn't expecting.

histedit: delete all non-actionclass related code Now that all actions have been migrated to the class format, we can delete all the unnecessary code that supported the old function format.

histedit: improve roll action integration with fold Previously the fold action would inspect it's class to figure out if it was a rollup or not. This was hacky. Now that finishfold is inside the fold class, let's modify it to check a function (which roll can override) to determine if it should be prompting for a commit message.

histedit: move finishfold into fold class Let's move the finishfold function into the fold class so we can modify it from the roll class more easily.

histedit: convert fold/roll actions into a class This converts the fold/roll actions into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness. The tests changed for two reasons: 1) We get a new 'empty changeset' warning because we now warn more consistently between normal histedit and --continue about commits disappearing. 2) Previously we were not putting the histedit-source extra field on the temporary fold commit during normal runs, but we were on --continue runs. By unifying these code paths we now consistently put histedit-source on the temporary fold commit, which changes some of the hashes in the backup bundles.

histedit: convert edit action into a class This converts the edit action into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness.

histedit: convert message action into a class This converts the message action into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness.

histedit: convert drop action into a class This converts the drop action into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness.

histedit: convert pick action into a class This converts the pick action into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness. The test output changed because previously pick would only report the commit disappearing if there were no merge conflicts. Now that we've unified the normal and the --continue flows, they act the same and we get the warning even after --continue.

histedit: integrate action class into flow This takes the newly added histeditaction class and integrates it into the histedit run and bootstrapcontinue logic. No actions implement the class yet, but they will be add in upcoming patches.

histedit: add a new histeditaction class This adds a new class called histeditaction. It represents a single action in a histedit plan. Future patches will integrate it into the histedit flow, then convert each existing action in to the class form one by one. This is part of a larger refactor aimed at increasing histedit robustness, maintainability, and extensibility.

histedit: allow histedit --continue when not on a descendant (BC) Previously we would not allow --continue if the current working copy parent was not a descendant of the commit produced by the previous histedit step. There's nothing really blocking us from continuing the histedit in this situation, so let's stop aborting in this case. This is technically a BC change, but it is making things more forgiving so I think it's ok. In the future we will likely add an 'exec' action to histedit, which means the user can do whatever they want during the middle of a histedit (like perhaps calling 'hg update'), which means we'll need to support this case eventually anyway.

tags: explicitly log which tags cache file is being written We now have multiple tags cache files. Record exactly which file is being written. This should help aid debugging into performance issues with any single filter.

tags: write a separate tags cache file for unfiltered repos Since we changed the format of the tags cache, we should bump the filename. Before this patch, "tags" was being used for unfiltered repositories. Change the naming scheme to be consistent and ensure that a new cache file is used. While I was here, I updated the docs to describe the existence of multiple caches. I also added explicit test coverage for the creation of the unfiltered tags cache.
