localrepo: replace status method with a shim The path of the righteous man is beset on all sides by the inequities of the selfish and the tyranny of evil men. Blessed is he, who in the name of charity and good will, shepherds the weak through the valley of darkness, for he is truly Mercurial's keeper and the finder of robust methods. And I will strike down upon thee with great vengeance and furious anger those who would attempt to poison and destroy Mercurial's codebase. And you will know my name is the Lord when I lay my vengeance upon thee.

workingctx: have status method call super instead of customized code. The old code is unneeded now that basectx has the ability to calculate the status between two context objects. Now, we use the objected oriented pattern called 'super'.

basectx: copy localrepo.status method Now that all the pieces are in place, we copy the status method from localrepo. In the next few patches, we will remove the old implementation.

committablectx: cache _status in _poststatus A future patch will remove the old workingctx.status which caches the status of the working directory, therefore we now cache this status in the poststatus hook of committablectx.

committablectx: simplify caching the status Previously, workingctx had custom variables for the unknown, ignored, and clean list of files of status. These then got moved to committablectx and, after the refactoring of localrepo.status, are no longer needed. We, therefore, simplify the whole mess. As a bonus, we are able to remove the need for having 'assert'.

localrepo: remove cache code now handled by _prestatus This patch removes the last of the 'working' variable that was sprinkled throughout localrepo.status which paves the way for future patches to use the object oriented design of contexts to handle calculating the status.

workingctx: add note about super._prestatus calling manifest

basectx: preserve loading the cached manifest in _prestatus This is just a copy from localrepo.status and is a small step to removing that method entirely. The prestatus hook is only called for changectx's, thereby ensuring that the same behavior is guaranteed.
