histedit: fold in memory
Update the folding code to works in memory instead of applying patches on the
working directory. This is cleaner, faster and prepare the removal of the whole
patching logic.
This new collapse function will probably move into core sooner or later. A lot
of other rewriting operation may benefit from it.
